App version 0.86.0

Golf Caddie FvB

GPS distances to the green, shots detected by the Apple Watch, scorecard, handicap and training — without a subscription, an account or a server. This is the complete user manual.

The same guide is built into the app under Settings → Guide, where it also works without a connection on the course.

01

Getting started

Set up a course and start your first round.

Setting up a course

The app ships with more than 800 courses in Germany, including holes, greens and hazards. They come from OpenStreetMap, a free map maintained by volunteers, and are available without a connection. That is why there is no subscription and no sign-up.

  1. Tap “Course” and search by name — or use GPS to list the courses nearby.
  2. Pick a result. Courses from the built-in database are ready at once; others are loaded from OpenStreetMap.
  3. Check that the holes look right — whatever is missing in OpenStreetMap is missing here too.

NoteIf your course is missing or holes are incomplete, you can walk the line of play yourself. See “Course data”.

Starting a round

If you are standing on a course, the app selects it by itself — it appears at the top of the home screen. If you have deliberately chosen another one, your choice stays until you stand on a different course.

Tap “GPS”. The app finds the nearest tee and starts there — even if that is the 10th.

If you interrupt a round you can resume it on the same day. After that a new one begins: golf has no two-day round, and a half-stale scorecard would be worse than none.

Changing the language

Settings → Sprache / Language. You can choose German, English or “Automatic”, which follows the system language.

NoteThe new language takes effect the next time the app starts. The app does not force a restart — that is considered bad practice on iOS.

On the hole

Distances, pin position, hazards.

Reading distances

Three figures are shown: front of green, centre and back. The centre is usually the number that matters; the other two tell you how deep the green is.

Measured straight from your position to the target. A dogleg is longer on foot than the figure shown.

For any other point, tap the map: the label shows how far it is from you and how much is left from there to the green. Tapping the label removes the point.

The map moves along as you walk and shows you and the green together. If you move it yourself, it stays put; the arrow on the right brings it back.

Setting the pin

The centre of the green is an average. Only someone who can see the pin knows where it is today — so you can place it by hand.

  1. In the caddie view, tap “Set flag”.
  2. Tap the map where the flag is today.

The button then shows the distance to the flag. The position applies to this hole and this round; the next round starts without it.

Wind and “plays like”

The app fetches the weather for your position. From about 5 km/h of wind it uses wind direction and playing direction to work out how far the shot plays: headwind costs distance, tailwind gives back a little less than headwind costs.

The caddie view shows the wind correction and suggests a club for the corrected distance. Together with the elevation change this gives the distance the shot “plays”.

Rules of GolfIn tournament mode the correction is switched off. The weather report itself remains allowed (Rule 4.3a).

Elevation change

If the green is markedly higher or lower, the app shows how far the shot “plays”. It uses a terrain model; where none exists it falls back to the less accurate GPS altitude and says so.

Rules of GolfIn tournament mode this is not shown — Rule 4.3a prohibits gauging elevation changes.

Switching to another hole

The arrows move one hole forward or back, and from 18 round to 1.

To jump, tap “HOLE” with the small arrow. The list shows every hole with par, length and your score — useful for entering a result afterwards.

Fly-over

On the right of the hole map, “Fly-over” starts a 3D preview: the camera flies from the tee along the line of play to above the green, then returns to the usual map.

Touching the map ends the flight at once. The button only appears where the hole has a line of play.

Shots and score

Have them detected, or enter them by hand.

Detect shots automatically

If you wear the Apple Watch it recognises your shots from the motion and reports them to the iPhone. Nothing to type.

The watch vibrates briefly and keeps showing distances. The iPhone assigns the club; the shots appear there as dots on the map, and that's where you correct them, during the hole or after the round.

On the iPhone, detected shots appear as numbered dots on the map, the latest in yellow. “Last shot” shows how far you are from it — that is, how long the shot was. When a swing arrives, a short message appears at the top.

NoteCan be switched off under Settings → Swing detection. The sensors use noticeable battery.

Score without typing

When you leave a hole without a score, the app enters the shots — detected or set by you — plus penalty strokes and putts. If you entered no putts, it assumes two. When you finish the round, the same applies to every hole.

A watch symbol on the scorecard marks a score that was filled in this way. Anything you enter by hand always takes precedence.

NoteDetection is not yet perfect. Several shots in quick succession, for example in a bunker, can merge into one. A look at the scorecard after the round is worthwhile.

Setting shots yourself

At the ball: tap “Shot” and choose the club. The shot appears as a dot on the map and counts towards the score. If the watch reports a swing at the same spot, it is the same shot — it is not counted twice.

Afterwards, from the green for example: tap the map where the ball was and choose “+ Shot”. The app slots it in between the shots before and after.

Penalty strokes

Tap a shot to open it. There you enter penalty strokes — for a ball out of bounds, in the water or unplayable. They appear in red on the shot and count towards the score.

Reviewing rounds hole by hole

History → open a round → tap a hole. The map shows the hole, every shot with its club and the distance to the next shot, penalty strokes in red and the putts on the green. Switch holes at the top.

The map shows what was recorded. If a shot is wrong — say a chip from the neighbouring green that was assigned to the tee — tap it: change the club, add penalty strokes, remove it, or choose “Move on the map” and tap where the shot really was. The round's score stays as it is.

Sharing a round

History → “Share” below the round card. The app turns the card into an image — score, Stableford, GIR, putts, penalty strokes and playing partners — and opens the share menu for messages, mail or photos.

Rebuilding a round

If the recording of a hole is completely wrong, rebuild it from memory:

  1. In the hole view, clear the recording via “…” → “Remove all shots”.
  2. Tap “+ Shot”, tap the map where the ball was, and choose the club. Repeat for every shot.
  3. If a shot is in the wrong place in the order, open it and move it up or down with the arrows.
  4. If a shot is in the wrong place, press and hold it until it vibrates, then drag it to where it really was.
  5. Around the green it gets tight: the “Green” button at the bottom right of the map zooms in on the green and its surroundings, “Hole” shows the whole hole again.

The history shows each round as a card with score, Stableford, GIR, putts, penalty strokes and score distribution; from there you go straight to the scorecard, the holes or editing.

How the app learns your clubs

Every club you assign to or confirm for a detected shot is an example: swing and distance to the green from where the shot was played. For a new swing the app picks the club of the most similar examples — a slow swing just short of the green becomes your 9-iron if that's what you chip with.

NoteThe app learns only from your corrections, not from its own guesses. The more shots you put right after a round, the better it gets.

Correcting shots

During the hole: tap a dot on the map. There you can change the club and penalty strokes, or remove the shot — a practice swing that was counted, for example. Corrections happen on the iPhone; the watch does not distract you with questions while you play.

After the round: History → open the round → “Edit scores”. Every score can be changed hole by hole.

After the round the shots add up once score and putts are entered: the app then counts exactly score − putts − penalty strokes to the green and sets aside surplus swings — rattling clubs, arm movements, two swings at the same spot. The hole view shows the sum; set-aside swings are greyed in the list and can be brought back with “Count”.

Swing tempo

For every detected shot the watch measures how long the backswing and downswing took. The ratio is your tempo: tour players are at about 3 : 1, whether they swing fast or slow.

Statistics → Swing tempo shows your typical ratio, the times, how consistent it is from shot to shot and the tempo of your last round. For clubs you have confirmed it is also shown per club. Individual shots show it in the hole view.

NoteNot every swing gives a number: chips and half swings have no recognisable backswing, and swinging straight out of walking means no still address. Then the watch leaves the tempo out. Practice swings don't count.

Practice swings

On the wrist a practice swing looks like a shot. It can only be told apart afterwards: after a shot you walk to the ball, after a practice swing you stay put.

If you barely move across several swings, the app treats it as practice and does not count it. On the driving range it therefore counts nothing at all.

NoteThe watch needs location access for this. Without it the app cannot tell a practice swing from a shot.

Strike sound (test)

A practice swing makes no strike sound. That is why the watch can listen, as a test — the motion sensor alone is too slow to notice ball contact; the microphone is not.

For now the sound decides nothing. It goes into the diagnostics as figures, so that real rounds can later settle what a strike sounds like.

NoteNo audio is stored or sent. The two seconds around each swing become five numbers, and the audio itself is overwritten straight away. The watch shows the orange microphone dot meanwhile.

Turn it on under Settings → Swing detection → Listen for the strike. It is off by default.

Entering the score by hand

Plus and minus on the caddie view or on the watch. The app accepts at most 20 strokes on a hole — enough for open stroke play too.

Putts are entered separately, with the length of each one if you like. The putting analysis is built from that.

Finish round

The app asks whether the round should go into your history. A round without a single stroke is not saved — it would distort every statistic.

Finishing stops location tracking and shot detection, on the watch too — whether you save or discard. The app then summarises the round: birdies, pars and bogeys, and for individual rounds whether you played to your handicap. “Done” takes you back to the home screen.

Scoring and handicap

Stroke play, Stableford, match play, course handicap.

Stroke play or Stableford

Settings → Play mode. Stableford shows points instead of strokes, 2 points for a par. The change applies to the scorecard, your history and the watch at once.

Playing partners and standings

The people icon at the top of the scorecard: add up to three playing partners there. At the very top are everyone's scores for the hole being played — a tap on plus or minus is enough.

The standings show strokes against par, skins and, with handicaps, Stableford points for everyone. Skins: whoever alone has the best score on a hole wins it; on a tie it carries over to the next hole. A hole only counts once everyone has entered a score.

“Calculate with handicap” needs a playing handicap for every partner; yours comes from your handicap index and the course rating. The switch applies to both standings and match play.

NotePlaying partners stay until the round ends, even if the app is closed in between. Afterwards they appear with their score on the round card.

Match play

The scorecard can run a match against players you have entered. It counts holes, not strokes — once someone is more holes up than remain, the match is decided.

For a net match, enter the course handicaps. The lower plays off scratch and the higher receives the full difference.

Strokes gained

Strokes Gained shows where you gain or lose strokes — split into off the tee, approach, short game and putting. Each shot is compared with the number of strokes it takes on average from there — raised to your level from your previous rounds. Plus means better than your own average.

It is based on the shots of the round with position, club and penalty strokes, as corrected in the hole view. The lie — fairway, rough, bunker, water — comes from the areas of the hole.

For putting the app needs the length of the first putt. If you don't enter it, it estimates: 4 m after a chip, otherwise 9 m. The card says on how many holes it estimated.

NoteShown after every round in the summary and in the history, across all rounds in the statistics.

Team rounds: scramble, foursome, best ball

During the round, choose the format below the round card on the home screen — or later inside the round in the history.

Team rounds appear in the history, marked as such. They do not count towards the handicap index, statistics, awards or training advice — those are about your own performance. Club distances from the watch still count: your swings are still yours.

NoteAfter every round, the next one starts as individual again.

Handicap

If a round doesn't count towards your handicap because no rating applied when it was saved — say the wrong gender was set in Settings — you can fix it: History → round → “Apply course rating” and choose the tee you played from.

The “Handicap” tile works out your course handicap for the chosen tee from handicap index, course rating, slope and par.

Since 2024, 9-hole rounds count for handicap: the app completes the nine holes played with the result expected for your index on the other nine. Rule of thumb: about 19 net Stableford points over nine holes keep your index. Each hole counts at most net double bogey.

NoteFor many courses the app already includes course rating, slope and par, separately for men and women, taken from the club's rating table. If they are missing, the app can only estimate and says so. You don't have to type them in: the app reads them from a photo of the scorecard, see “Course data”.

Clubs and equipment

Fill the bag, let distances be learned, set limits.

Adding clubs

Under “Clubs” you build your bag — with make and model if you like. You can enter the distance or let the app learn it.

NoteMore than 14 clubs is not allowed in competition: two penalty strokes per hole, four at most. The app points this out but does not prevent it.

Learned distances

From two consecutive positions the app knows how far your shot went. Many such measurements give your real club distance — not the one from the brochure.

Only what stands out from GPS noise and exceeds ten metres is measured. A practice swing or a mishit chip therefore does not distort the statistics.

Only confirmed full shots count towards the distance: placed by hand, or confirmed or corrected in the hole view. The club of an automatically detected swing is a guess — the app learns no distance from it. And a 7-iron chip from 30 m says nothing about how far you hit the 7-iron, so shots where the green was much closer than the usual distance don't count.

Dispersion

From six confirmed full shots with a club, the hole map shows a yellow dashed ellipse ahead of you: that is where the suggested club lands on average, with about two thirds of your balls inside.

The suggestion also names the average distance, the spread in length and to the side, and any clear tendency to the left or right. It is measured against the line of play, not the green: a tee shot down a dogleg is not a hook.

NoteIf no ellipse shows yet, confirmed shots are missing. After the round, confirm or correct the clubs of the detected shots in the hole view.

Shortest and longest distance

You can set a range per club. That helps club selection: a wedge you play between 40 and 90 metres is not the same as one with a single figure.

Tournament mode

What is allowed in competition — and what disqualifies you.

What the mode is for

Rules of GolfRule of Golf 4.3a separates two things: measuring a distance is allowed, interpreting it is not.

Allowed: “It is 147 metres to the pin.” Not allowed: “The green is eight metres higher, plays like 155.” And not allowed: “Take the 7 iron.”

Without this mode the app is a trap in competition: it looks like a permitted distance-measuring device but also shows elevation adjustment and club selection. Opening it is already the breach.

Rules of GolfPenalty: the general penalty — two strokes in stroke play, loss of hole in match play. A second breach means disqualification.

What changes

Turned off: Club recommendation, Elevation-adjusted distance, Wind-adjusted playing distance.

The values are not hidden — they are never computed in the first place.

What stays: Distances to green, pin and hazards, Scorecard and statistics, Shot recording — only analysed after the round, Weather report, without conversion into playing distance.

The watch still reports detected shots, but without a club name.

During the round “TOURNAMENT” sits above the hole number, so the mode is not forgotten.

The Local Rule comes first

NoteWhether distance-measuring devices are permitted at all is decided by the committee through a Local Rule. Without it even plain distance is forbidden — then the phone belongs in your bag.

Tournament mode makes the app conforming, not your entry.

Apple Watch

Distances on your wrist, shots without typing.

Setting up

The watch app installs with the iPhone app. When you start a round on the iPhone, the watch app opens by itself and starts shot detection. It stops when the round ends.

  1. Allow location — otherwise the watch only uses the last position the iPhone sent.
  2. Allow motion data — otherwise it detects no shots.
  3. On first use, start a round on the iPhone so the watch knows the hole.

During the round

The first page shows only what you look at the watch for: front, centre and back of the green, below that “plays” with wind and elevation, and the wind as an arrow. Up means towards the green, not north.

The watch calculates distances from its own GPS, even when the iPhone is in the trolley. A small iPhone symbol below the number shows when it comes from the iPhone instead.

The arrows next to the hole number change the hole, and the iPhone follows. Likewise the watch follows every hole change on the iPhone.

Swipe for score and putts, shot detection and diagnostics. Entries are never lost when the iPhone is out of reach — they are delivered later.

For the duration the watch starts a golf workout. Without it iOS would suspend detection after a few minutes.

Training and analysis

Where the strokes go, and what to practise.

Training plans

Under “Training” you'll find plans from beginner to handicap 12, plus a short-game focus and a pre-round warm-up. Each plan has a weekly schedule and milestones to tick off.

Tap any exercise in the weekly schedule to see step-by-step instructions with a tip. All exercises are also listed in the exercise library.

Training recommendations

From your played rounds the app works out which area costs you the most strokes — with your measured figure and a benchmark for your handicap beside it.

NoteFrom a single round the app says nothing. Eighteen holes are a day's form, not a weakness, and practising on that misses the real problem.

Every finding states how many holes it rests on. A finding from thirty holes is not the same as one from two hundred.

What cannot be judged

If you enter no putts, the app can say nothing about putting. Rather than stay silent it names the gap, so you know what to record.

Awards

What there is to earn along the way.

How they are awarded

Awards come for consistency and for single good rounds — rounds played, few putts, fairways hit. They check themselves after every saved round.

NoteSome awards carry a different title depending on the gender you set. You will find the setting with your player details; it also affects how lengths and tees are judged.

Course data

Where they come from and how to improve them.

Origin

All courses come from OpenStreetMap. That is why the app needs no subscription — and equally why some holes are incomplete.

Course data © OpenStreetMap contributors.

If OpenStreetMap doesn't know a course, its holes sometimes come from official aerial images: an image recognition model found the greens, the hole numbers come from the club's course plan, checked against the scorecard lengths. Aerial images © GeoBasis-DE/LGLN (2026), CC BY 4.0.

Which courses are included

Under Choose course → “All courses in the app” you'll find every course in the built-in database, sorted by distance and with its data status: holes with par from the club's scorecard, holes from OpenStreetMap, only some holes, greens only, or no map at all.

The same list is online at fvonbredow.com/golfcaddie/plaetze — there you can also sort it by distance from your location.

NoteIf your course is missing or has no holes, report it well before the round — in TestFlight via a screenshot and “Send Feedback”, with the course name and date. It can often be added beforehand.

Course check

Every time you pick a course, the app checks its data: do the hole pars add up to the par of the official rating for your tee? Which pars are only estimated from the length? Does every hole start close to the green of the previous one?

If something doesn't fit, the home screen shows “Check course data”. The details are under Course → Course check; an estimated par carries a question mark on the hole.

When two courses lie next to each other and use the same hole numbers, the app takes the holes that form a round together — a short walk from each green to the next tee.

For some courses, par, stroke index and length per hole come from the club's scorecard; the link is in the course check. There the app also compares every hole line with the length on the card and flags holes that probably belong to another hole.

NoteIf the total doesn't match and some pars are estimated, the app adjusts them to the official rating — but only where the length fits the new par. A par you set yourself always stays.

Photograph scorecard

OpenStreetMap hardly ever lists course rating, slope and par. For many courses the app has taken them from the clubs' rating tables; under Course rating a link leads to the table so you can check them. For all others they are on the scorecard and in the club's rating table — the app reads both.

  1. Course → Course rating (CR/SR) → “Photograph scorecard”.
  2. Photograph the table straight and sharp, choose a photo, or open the handicap table as a PDF from Files.
  3. Check the values read. If a colour is missing because the card only shows it as a colour, choose it yourself.
  4. “Apply”.

NoteThe PDF from the club website is the most reliable: its text is read directly, without text recognition. Everything is read on your device; the image is not stored.

NotePar and stroke index per hole are only preselected if they match the totals printed on the card.

Walking the line of play yourself

If a hole has no line of play, you can walk it: from tee to green, in that direction. The app remembers it for this course.

NoteThe direction matters. A hole recorded backwards gives distances that grow exactly the wrong way.

Your data

What stays on the device and what leaves it.

What stays on the device

Rounds, scores, clubs and awards live solely on your iPhone. There is no account, no server and no sign-in.

Under Settings → Export data you can write everything out — including to carry it to a new device.

What leaves the device

When searching for a course, the search term and map area go to OpenStreetMap. For weather your position goes to a weather service — there is no other way to fetch weather.

The rain radar receives your position rounded to about a kilometre. That is enough for the picture, and your exact location stays on the device.

NoteThere is no advertising, no analytics and no sharing with third parties.
