About this app

Every metre matters. Photograph your Concept2 monitor after a piece and Watta logs the whole workout for you. No typing, no spreadsheets, no lost erg photos in your camera roll.

Watta reads the distance, time, split, stroke rate and every interval from the screen, plus watts, heart rate, calories and drag factor when the monitor shows them. You check the numbers, tap save, and the session is in your log.

BUILT FOR CONCEPT2 ROWERS
• RowErg, SkiErg and BikeErg
• PM5, PM4 and PM3 monitors
• Steady state, intervals, 2K tests and every ranked distance

EVERY SESSION SCORED 0–100
The Effort Score weighs cardiac load, work output, pacing and stroke economy, so you can see how hard a session really was. Pair a heart-rate strap to the PM5 and Watta reads your heart rate from the photo and labels the piece by zone.

YOUR WHOLE TRAINING LOG
• Personal bests for every distance, on every machine
• Progress view: are your splits getting faster, and how much did you row this week
• Goals for a target time, weekly sessions or weekly metres
• Weekly streaks and 30 achievement badges

SET UP THE PM5 FROM YOUR PHONE
Send a workout to your PM5 over Bluetooth, ready to row.

COACHES AND CREWS
• Clubs, squads and leaderboards
• A feed of your crew's sessions, with reactions and comments
• Coaches can plan sessions, send them to rowers and review what was rowed

CONNECTIONS
• Import the sessions you upload to the Concept2 Logbook
• Push your logged workouts to Strava

TECHNIQUE CHECK (optional, paid)
Film 30 seconds of your stroke from the side and Watta measures it on your phone, then gives you a checklist and the one thing to fix first. The video never leaves your phone.

Watta is free to download and log with. Technique check is an optional in-app purchase.
