Watta

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. Distance, time, average split, stroke rate, watts, heart rate, calories — all captured and organised. Review individual sessions or zoom out to spot trends across weeks and months of training.

Join your club

Watta is built for squad training. Join your rowing club, connect with your squad, and see how your teammates are training. Club admins can create squads, manage members, and keep everyone connected. Whether you're part of a university programme, a local rowing club, or a national team, Watta keeps your crew together.

Compete on leaderboards

See where you rank. Leaderboards let you compare your performance against your squad, your club, or the wider Watta community. Push yourself to climb the rankings and celebrate when you hit a new personal best.

Social feed

Follow your teammates and see their workouts in your feed. React to big sessions and leave comments. Training is better when you're not doing it alone.
Works with all Concept2 monitors

Watta supports PM5, PM4, and PM3 displays, and any rowing machine with a screen. The AI handles different screen layouts, angles, and lighting conditions. It even works with photos of rowers, bikes, and ski ergs.


Row. Bike. Ski.

Watta isn't just for rowing. Log your sessions on the Concept2 RowErg, BikeErg, or SkiErg — all in one app.

Stop losing workouts to your camera roll. Watta gives you a proper training log that grows with every session. See your progress. Spot patterns. Get faster.
