Everything you check between shots
Yardages, green slopes, your stats and your swing, in one app. Most of it is free.
GPS yardages
Front, center and back of every green, carries over bunkers and water, and a satellite map of each hole with your line of play.
Shot tracking
Mark shots as you walk, or let the app pick up your swings. See how far each club really goes.
Stats that matter
Putts, fairways, greens and penalties, strokes gained, and your scoring trend over the season.
AI caddy and analyst
A club and a plan for each hole, adjusted for wind, temperature and elevation. After the round, a plain-English read on where the strokes went.
Handicap
Track your index from GHIN or let Parbook work one out from your rounds.
Friends and messages
Follow your friends' rounds live, send a note after a good one, and start group chats.
Tee times with friends
Set a tee time, invite your group, and see the forecast for your round. Everyone's scores land on one group card.
Preview any course
Search a course and walk it hole by hole before you go: the scorecard, each hole's map, and every green.
Works with no signal
Open the app in the parking lot and the course saves to your phone, greens and all, so yardages work in dead zones.
See the break before you putt
Greens are mapped from USGS lidar surveys, so you see the slopes the way the ground really sits.
- Slope map shaded low to high, with arrows pointing downhill and how steep it is.
- 2D or 3D: tilt and turn the green to see the ridges and tiers.
- Line up a putt: tap your ball and the cup for the curve, where to aim, and how hard to hit it at your green speed.
- Opens on its own when you walk onto the green, turned the way you walked up to it.
Film your swing. Get a plan.
Prop your phone up, hit a shot, and Parbook traces your body through the swing, then tells you what to fix and how.
- Traced replay through setup, top, impact and finish, from face-on or down the line. Works with slow motion.
- Scores and tempo, each marked as measured or estimated, so you know what to trust.
- You choose what it checks: turn checks on or off and set your own tempo goal, then re-check any swing.
- Faults tied to your rounds: a slice shows up next to the fairways you've been missing right.
- A fix plan with drill videos, a re-test, and a side-by-side with your best swing. Share it with your coach or friends.
Plan the round with your group
Pick a course and a time, invite your friends, and everything about the round lives in one place.
- Round forecast hour by hour for your tee time, with wind and rain.
- Weather heads-ups in the three days before, if storms or a washout are on the way.
- One group card with everyone's scores as you play.
- Saved for no signal: the course is on your phone before you get there.
