Every metre counts. Watta turns photos of your erg screen into a complete training log. Snap a picture of your Concept2 monitor after your workout, and AI extracts all your data automatically — distance, time, split, stroke rate, watts, calories, and more. No Bluetooth pairing. No cables. Just take a photo and you're done. Snap. Log. Done. Most rowers take photos of their erg screens after training. Those photos sit in camera rolls, never tracked, never analysed. Watta changes that. Upload a photo from your gallery and AI reads your PM5, PM4, or PM3 display in seconds - or any Rowing machine with a screen. Your data flows straight into your training log. You can also enter workouts manually if you prefer. Track every session See your full workout history in one place.
