# watta.
ai workout tracker for rowers. take a photo of the erg screen — we
read every number off it, score the effort 0–100, and roll your
training into clubs and leaderboards.
live on the app store today.
## what it is
every rowing workout ends with a screen full of numbers: time,
distance, split, stroke rate, heart rate. nobody types those into
a spreadsheet, so workouts evaporate.
watta closes the loop. point your phone at the pm5 (or pm4, pm3,
any erg display) and we read every number into a structured workout
— intervals, summaries, time trials. then we score the effort 0–100
by combining split, distance, time, and cardiac load. the score
surfaces hard sessions on days when the split alone lies.
## why now
- on-device vision models can now read pm5 screens reliably from a
phone photo
- rowers are fragmented across concept2 logbook (closed), strava
(general fitness), and a dozen abandoned apps
- clubs want shared training data, not splits dumped into a slack
channel by hand
## what's live
- ios app, on the app store
- effort score 0–100 with cardiac load weighted at 40%
- five hr zones (recovery, aerobic, tempo, threshold, max)
calibrated to each rower's resting + max
- ai photo-import for pm5 / pm4 / pm3 — intervals, summaries, time
trials
- multi-machine: rowerg, bikeerg, skierg
- clubs + squads, invite codes, leaderboards by effort, distance,
or time
- social: follow, react, comment on workouts
- free web calculators — split↔watts, pace, 2k predictor, weight
adjustment, hr zones — driving organic search and signups
## traction
