Curvalo

Curvalo is an iOS app that works as the logbook for your bet slips: you record them, follow them to the final whistle and see clearly how your bankroll is doing. It is a tracking and analysis tool only: no bets are placed in the app, there are no odds on offer and no money changes hands.

How it works

1. Scan the slip — point the camera at a paper slip or a screenshot from your betting app; AI reads every selection, the odds and the stake and matches them to real fixtures.
2. Save it — anything the scan could not read is corrected by hand before saving, or the slip is added manually.
3. Let it settle — Curvalo follows the matches on the slip and settles each selection as the game ends, sending a push notification on updates.
