Prepare. Play.
Analyze. Improve.
Prepare your course hole by hole, play with the GPS caddie, log your shots as you go. Grooves turns that into your stats, the area costing you the most, and the practice that goes with it.

01Prepare
The round is played
before you get there.
Pick your course and your tee. Grooves maps all 18 holes, places the hazards and builds your plan from your bag's carries. You walk every hole from your couch, and show up with a target per hole and a total to beat.
- ✓Built on your bag, not a tour pro'sEvery leg is computed from your clubs' average carries, which you enter once and which get refined as your shots are logged.
- ✓One plan per hole, and you can change itGrooves proposes a single line of play, computed on your real dispersion and its expected average score. Keep it, or change club and target shot by shot.
- ✓An expected total, before the first tee shotThe sum of hole-by-hole expectations, compared to the course par and to your level.
- ✓The paper notebook, for tournamentsIn competition the phone stays in the bag: the same plan prints on A5, one hole per page. The rest of the time, the screen is enough.

02Play
A caddie that advises,
and keeps score.
On the course, Grooves gives you the distance, the club and the line of play. And every shot you log fills in your round as you go: that is what makes the post-round analysis possible.
- ✓Front, middle and back distancesRecomputed continuously from your position. Drop a target anywhere on the map and you get the distance.
- ✓“Plays like” rather than “it is”Elevation and wind applied to the real distance, then mapped onto your bag's carries. The caddie hands you a club, not just a number.
- ✓One tap, and the shot is in your roundGPS position at the moment of the shot, with the club and the lie. Fairway hit is derived on its own. No notebook, no re-entry at the clubhouse.
- ✓With the Apple Watch, the phone stays in your pocketThe swing is detected on your wrist. You confirm on the watch, and that confirmation is what logs the shot. A practice swing does not count.

03Analyze
You finally know where
you lose strokes.
Every shot is logged with its position, so the post-round analysis is no longer guesswork. Grooves puts a number on what each area of your game cost or gained you during the round, against players at your level.
- ✓Five areas, one single unit: the strokeOff the tee, approach, around the green, putting, penalties. No more debate about what really costs you.
- ✓Compared to your levelThe benchmark is a player at your index, not a tour player.
- ✓The scorecard fills in as you playScore, fairways, greens, putts per hole: it comes from the shots you log, not from typing it all in at night.
- ✓The next plan takes it into accountYour real dispersion sharpens the expectations of the next notebook, hole by hole.

04Practice
Practice follows
from the course.
Grooves turns your measured weakness into a program: ready-to-play sessions from 15 to 90 minutes, over the timeframe you set yourself. Every new round readjusts what comes next.
- ✓Aimed at your weakest areasThe ones your round stats point at, not the ones you enjoy working on.
- ✓Sessions, not buckets of ballsEvery drill has a precise target and a number of balls to play. You show up, you play, you log your score ball by ball.
- ✓Readjusted every weekIntensity follows your results and the practice days you picked. A skipped session does not break the program.
- ✓You see whether it works, round after roundEstimated level, greens, fairways, putts per hole: your next rounds say whether the work paid off, and the program re-aligns on that.

Frequently asked
Everything you need to know.
What if I have no signal on the course?
Positioning uses the phone's GPS, not the network. Your round is kept on the phone and syncs when you are back online. The map and the hole plan, however, are loaded at the start of the round: if you begin with no signal at all, the map background may be missing. Load the course before you head to the first tee.
How is the club recommendation computed?
Grooves starts from the real distance to the target, applies elevation and wind to get a “plays like” distance, then compares it to your bag's real carries, which you enter and which get refined as shots are logged. Lie and penalties adjust the suggestion.
Doesn't logging shots slow the round down?
It is designed to do the opposite. A shot is logged with one tap: GPS position captured on the spot, with the club and the lie, no distance entry and no notebook. Fairway hit and hole score are derived from what you logged.
Do I need a watch or a sensor?
No, the phone is enough: one tap per shot. With an Apple Watch, the swing is detected on your wrist and the watch asks you to confirm: that confirmation is what logs the shot, so a practice swing does not count. The watch app installs from the Watch app on your iPhone.
I already track my rounds in another app. Can I bring them over?
Garmin sync and Golfshot import are available. For other sources (Hole19, Shotscope, Golf GameBook, Spider Golf, TAG Heuer Golf), you enter the scorecard by hand. And if you play with the Grooves GPS caddie, there is nothing left to re-enter.
I'm a beginner with no statistics. Can I start?
Yes. At first, Grooves uses your index, your available slots and your facilities to give you a program and targets within reach. The shots logged during your rounds then sharpen the diagnosis and tighten the program around your real weaknesses.
What if I miss a week, or go on holiday?
A session can be moved within the week or skipped without breaking the program: the rest is recomputed. You pick your practice days when creating the program and you can change them along the way.
Does it replace a human coach?
No, and that is not the point. A coach teaches you a movement. Grooves replaces the empty time between two lessons: it gives you the structure to groove it at the range, and you can share your program with your coach.
Is it really free?
Grooves is in beta and free during this period. No credit card required. We will let you know well in advance if that changes.
