FAQ

Common questions

How easy is the app to use?
Point your phone camera at the player from the side, upload the video — the AI does the rest. No technical knowledge needed.
What equipment do I need?
Just a phone that shoots video at 30fps. A tripod helps but a friend can film you. No special cameras or sensors required.
Who can see my recordings?
Only you can see your recordings and data unless you choose to share them with a coach.
How accurate is the analysis?
We aim for at least 90% accuracy for most shots depending on video quality. Side-on angles give the best results.
How much does it cost?
OnCourtAI is completely free while we develop the app. Full access to all features at no cost.
How do I install the app?
Open oncourtai.co.uk/mobile-app in Safari (iOS) or Chrome (Android), tap share/menu, then "Add to Home Screen". Installs in seconds.
