The Concept2 companion app you have been waiting for
Watta is built specifically for Concept2 ergometers. Point your camera at the PM5 monitor, and AI extracts your workout data instantly. No Bluetooth pairing, no manual entry, no ErgData crashes — just fast, reliable erg tracking.
The Problem
ErgData and the Concept2 logbook have limitations
ErgData requires Bluetooth pairing that frequently disconnects. The Concept2 online logbook is functional but lacks social features, training insights, and modern mobile design.
Bluetooth connectivity is unreliable
Pairing a phone to the PM5 via Bluetooth is finicky, especially in busy gyms with multiple machines. Lost connections mid-workout mean lost data, which is frustrating after a hard session.
No unified experience across Row, Ski, and Bike
Concept2 users with multiple machines want a single place to track all their erg work. Most apps focus only on rowing or treat the three machines as completely separate activities.
How Watta Helps
No Bluetooth Required
Watta uses AI-powered OCR to read your PM5 screen from a photo. No pairing, no connectivity issues, no mid-workout disconnections. It works every time.
RowErg, SkiErg & BikeErg
Track all three Concept2 machines in one app. Switch between row, ski, and bike workouts seamlessly, with each session getting its own Effort Score.
Strava Integration
Sync your Concept2 workouts to Strava automatically. Your erg sessions appear alongside your other activities without any extra steps.
How It Works
Snap your erg screen
Take a photo of your PM5 display after your workout. Gallery upload works too.
AI extracts your data
Watta reads every metric — time, split, distance, stroke rate, heart rate, and calories.
Get your Effort Score
A 0-100 score combining cardiac load, work output, pacing, and economy shows exactly how hard you worked.
