How should I film my serve?: Film from behind or from the side, with your whole body and the top of the toss in frame. Prop the phone at about waist height and keep it still.
The app says it didn't find a serve.: Make sure the clip shows one full serve from setup to landing, in decent light, with nobody else in frame. Clips under about 15 seconds work best.
Are my videos uploaded?: No. Analysis runs on your phone and videos never leave it. See the privacy policy for what we do collect.
How do I delete my data?: Deleting the app removes your videos, scores and history. Email us to delete anonymous usage data.
