Support
Tell us your iPhone model, the iOS version and the Optic version (it's at the bottom of Settings in Optic). If a serve was scored wrong, open the session, tap Share session data and attach the file.
Getting set up
Where should I put my phone?
Side-on to your serve and level with you, so you face the camera in your stance. A fence or a tripod both work, in portrait or landscape. Keep your shoes and head in the frame, with room above your head for the whole toss. The checklist on screen turns green when it's ready.
Which iPhones work?
Any iPhone with iOS 26 or later. The coach's note needs Apple Intelligence; without it, everything else works the same.
Can I use a video I already have?
Yes. Import a video from Photos or Files. Slow-motion videos work. A long video keeps processing when you lock the phone, with the progress on the Lock Screen.
Results
Why is a serve marked "not sure"?
Optic couldn't see well enough to measure it. Maybe the ball was lost against the background, the toss went out of the frame, the phone moved, or the ball was too close to the edge of the picture. The card tells you which. You can replay the serve and mark the top of the toss yourself.
A serve wasn't counted
Optic leaves out caught tosses and practice swings on purpose. Open the session to see the motions it didn't count and add one back, or pick a moment in the video to analyse.
The score looks wrong
Check that the phone was side-on, level and steady, and that your whole body was in the frame. If it still looks wrong, send us the session file (see above), so we can look at the same numbers you saw.
Your data
Does Optic upload my videos?
No. Everything is analysed and stored on your iPhone. The privacy policy has the details.
How do I delete my data?
Delete a session in the app, or use Settings › Delete all sessions. Deleting the app removes everything Optic stored on the phone.
