240fps slow motion
Speed mode records up to 240 frames per second on the wide camera for true slow motion.
Accuracy mode with LiDAR depth
On iPhone Pro models, 60fps video with live LiDAR depth. It’s the default on those phones.
Swing mode
Record one swing; it stops itself 1.5 seconds after you swing and trims the clip to the motion.
Practice mode
Swing continuously for up to 30 minutes; every swing is detected by motion and sound and saved as its own clip.
Framing coach
Pick what you want to check and Certus sets face-on or down-the-line, then talks you into frame: “Move closer.” “Full body not in frame.” Plus a silhouette and a level.
Hands-free start
Click an AirPods stem (on the iPhone or the iPad) or tap the Watch, with a 0 to 15-second countdown before recording starts.
Honest frame-rate badge
When heat or Low Power drops the frame rate, the badge says so and tells you why.
Motion-blur control
Shutter speed is capped for the frame rate, so the club isn’t a smear.
Camera angle on every clip
Pick face-on or down-the-line in the recorder and it remembers; imported clips are detected automatically, and you can change it on any clip.
Live mirror on iPad
The iPhone’s camera shows on the iPad in real time, so you can watch your swing while you make it without recording anything. The link is encrypted peer-to-peer and needs no internet.
Instant replay on iPad
Each recorded swing lands on the iPad within seconds and starts playing on its own, slowed, on a loop.
Run the iPhone from the iPad
Start and stop recording, switch between Mirror, Swing and Practice, and star swings so they save as favorites on the phone.
Review on the iPad
Draw, slow down and step frame by frame, with joints, hands and body lines analyzed on the iPad itself.
Free companion
The Coach Station needs no subscription. Sign in with a subscribed Certus account, or subscribe on the iPad, and it opens the full app.
Skeleton overlay
The full body tracked joint by joint through the whole swing, on-device.
24 body-line overlays
Sway, side bend, knee flex, hand depth, setup lines and more, each marked Fixed or Tracks.
Readouts in real inches
Live readouts on 13 overlays, in inches or degrees, with tour ranges on the key ones. Inches appear only when LiDAR gives the clip real scale.
No reading without a view
If the camera angle can’t see a movement, Certus shows nothing rather than a guess.
Address Ghost
A see-through freeze of your setup laid over the moving swing, with an opacity slider.
Hands trail
Trace the path of the hands through the swing.

Map yardage adjusted for elevation, wind and air. Elevation is sampled along the hole from 10 m terrain data in the US (about 90 m elsewhere), never as a single tee-to-green delta.
Head vs tail wind
Only the head/tail component changes distance; a tailwind helps about three-quarters as much as the same headwind hurts.
