Step on the tee like you’ve played the hole before. Fly over it first, see where the trouble is, and play to a number that already accounts for the wind, the elevation and the air.
You get live distance to the front, center and back (measured where your line crosses the green’s edge), reach and carry numbers for the bunkers and water ahead, rings off the green, and elevation steps marked on the line. It’s all drawn on 3D satellite imagery with the greens and hazards outlined.
Drag the aim point anywhere. It snaps to the fairway centerline, bends around doglegs, and shows the plays-like number and the club from your own yardages.


Plays-like is three physical adjustments, each with its rule written down, added to the yardage on the map.
The same rules the app uses on the course.

Air pressure is held at 1013 mb here. On the course the app reads it live.
Planning tomorrow’s round? Set a tee time and every hole gets the forecast wind for when you’ll actually reach it, counting from your starting hole at about fifteen minutes a hole.
Tap the wind card and animated streaks flow across the hole in the wind’s true direction. The harder it blows, the more streaks there are and the faster they move.
A Low, Moderate or High weather-impact rating for today, tomorrow or any day in the next ten, with an outlook explaining why. There’s also a wind compass that turns the forecast into a distance table, plus official severe-weather advisories and the UV index.

Every green-mapped course comes with a color-coded slope map and a 3D green you can spin. Your subscription includes 12 green-mapped courses a year, downloaded once and kept for offline play.

Open the full-screen slope view and tap 3D. The green rises off the screen so you can rotate it, pinch to zoom and find the shelves. It’s calibrated against the slope map, so it tells you the actual fall in inches across the surface.
Land on the right tier and the putt is flat. The map shows you which tier that is before you pull a club.
The tee-club call ranks your clubs by expected strokes gained on this hole. It uses only your own tracked shots, your real carry spread once a club has enough of them, and whether you run out of fairway. Every number shows how many shots it’s built on.
Only a few shots with a club? It’s grayed out as provisional. Two clubs within 0.05 strokes? It says it’s too close to call and lets you hit the one you trust. Turn on pressure mode and it uses your tournament rounds, flagging the clubs that fold when the card counts.
Rule 4.3 lets you use distance in competition, but not slope, wind or club advice. One tap on the T at the top of the map’s left-hand buttons puts Certus in exactly that state, and the T turns solid green so nobody in your group has to ask.


Tap the T and Certus shows raw distances only. Plays-like, wind, slope and the caddie’s clubs stay off until you switch it back.
Mark it as a tournament round. Once you have three tournament and three casual rounds, Under Pressure on Stats shows what changes when the card counts.
Log a round on the course or after it, on your phone, your Watch or paper. Every method feeds the same stats.
Tap to mark each shot where you’re standing. Certus records the club, the lie and the distance, and works out the hole score for you to confirm.
Enter the card hole by hole: score, putts, fairways and greens. It saves as you go, and a card entered later is dated the day you played.
Keep score, putts and fairways from your wrist. If the phone is out of range, taps wait on the Watch and sync later.
Print a Certus Scorecard or Shot Tracker with your tees filled in, play with a pencil, then scan it. The round reads straight into the app.
Standing on the tee with nothing logged? Certus reminds you to log the drive, and notices if you skipped it. Walk to the next tee and it moves on by itself.
Put a Log Shot control on the Action button or in Control Center, or tell Siri “Certus Golf, I made a 5.” The phone can stay in your pocket.
The banner shows the hole, your score and the yardage to the middle, with front and back underneath. + Shot marks where you’re standing; on the green it turns into Pin and putts.
It moves to the next hole with you, even if the app was closed, and the hole and score sit in the Dynamic Island while you use the phone.

The Watch measures to the flag with its own GPS and moves between holes by itself. Plus and minus set the score (the first tap lands on par), and putts and fairway are one tap each.
Wind and temperature come from the phone, and the total moves as you tap.


Every course you’ve played gets its own page: scoring average, your strokes gained there, par-3, 4 and 5 performance, your strongest and weakest holes, and a map of your tee shots on every hole, each numbered with the score you made.
Before you go back, read what the coach says about it, and print the Course History report for the first tee.
