Performance tracking for rowers who compete

By the Watta Team · Updated 10 August 2026

Competitive rowing demands precise training data. Watta captures every erg session with AI-powered OCR, tracks personal bests across all standard distances, and provides Effort Scores that quantify training load — because at the competitive level, every detail matters.

Rowing App for Competitive Rowers: Watta is a free, AI-powered rowing workout tracker. Snap your erg screen to capture data instantly. Get a 0-100 Effort Score combining cardiac load, work output, pacing, and economy. Track heart rate zones via the Karvonen method. Join clubs and squads to train with your crew.

The Problem

Training data is scattered across multiple platforms

Competitive rowers use Concept2 logbook for metres, Strava for sharing, spreadsheets for training plans, and WhatsApp for coach communication. There is no single source of truth for erg data.

Tracking training load is manual and subjective

Most competitive rowers use session RPE or rough estimates to track training load. Without an objective, automated intensity metric, periodisation decisions are based on feel rather than data.

Personal best tracking across distances is incomplete

Competitive rowers care about PBs across 500m, 1K, 2K, 5K, 6K, 10K, half marathon, and marathon. Keeping accurate records across all these distances is tedious without automation.

How Watta Helps

🏆

Comprehensive PB Tracking

Watta automatically tracks personal bests across all standard erg distances — 500m, 1K, 2K, 5K, 6K, 10K, half marathon, and marathon. Every PB is recorded and celebrated.

📊

Effort Score for Periodisation

Use Effort Scores to map training load across mesocycles. Identify base, build, peak, and taper phases with objective data rather than subjective feel.

Frequently Asked Questions

How accurate is Watta's OCR for interval workouts?

Watta's AI is trained to read interval summary screens from the PM5, including individual split data, rest periods, and total distance. It handles most standard interval formats accurately.

Can Watta help me prepare for selection?

Yes. Track your PBs across standard distances, monitor Effort Score trends across training blocks, and ensure your fitness is peaking at the right time. Data-driven preparation gives you an edge.

Does Watta support weight-adjusted scores?

Yes. The Effort Score algorithm includes a body weight factor based on the Concept2 weight adjustment formula, providing a fairer intensity metric across different body types.

Can my coach see my workouts?

Yes. If your coach uses Watta, they can follow you and see your workouts in their feed. Coaches can also create clubs with squads to view all athlete data in one place.
