Track your rowing for weight loss — the simple way
Rowing is one of the most effective exercises for weight loss, engaging 86% of your muscles in a low-impact, high-calorie-burn movement. Watta makes tracking your rowing sessions effortless with AI-powered photo logging, calorie data, and Effort Scores.
The Problem
Hard to know if rowing workouts are effective
Without tracking calories, distance, and intensity, it is impossible to know if your rowing sessions are contributing meaningfully to your weight loss goals. Many people row aimlessly without data.
Motivation fades without visible progress
Weight loss from exercise happens gradually. Without a record of sessions completed, distances rowed, and fitness improvements, it is easy to feel like nothing is working and quit.
Calorie estimates from other apps are unreliable
Generic fitness trackers estimate rowing calories based on time and body weight alone. The Concept2 monitor calculates calories from actual power output, which is far more accurate but rarely captured.
How Watta Helps
Accurate Calorie Tracking
Watta extracts calorie data directly from your Concept2 PM5 screen, which calculates calories from actual power output. Far more accurate than watch-based estimates.
Effort Score for Consistency
The 0-100 Effort Score gives you a clear target for each session. Aim for consistent scores to build a sustainable exercise habit rather than burning out with unsustainable intensity.
Streaks & Achievements
Watta rewards consistency with weekly streaks and achievement badges. Stay motivated with tangible milestones as you build your rowing habit for weight management.
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.
