Erg tracking built for the long game

By the Watta Team ยท Updated March 2026

Masters rowing is about sustained performance, injury prevention, and training smart over decades. Watta gives you effortless erg logging with AI-powered OCR and Effort Scores that capture the quality of every session, not just the split.

Rowing App for Masters 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

Recovery matters more than ever

As a masters rower, the line between productive training and overtraining is thinner. Without a way to objectively track session intensity over time, it is easy to push too hard or not hard enough.

Comparing to open-age benchmarks is misleading

Most rowing apps and leaderboards focus on open-age performance. A 1:50 split means something very different at 45 than at 22, and age-blind tracking can be demoralising rather than motivating.

Consistency tracking over years is difficult

Masters rowers often train for decades. Spreadsheets break down over time, Concept2 logbook is functional but limited, and most apps are designed for short-term training cycles rather than multi-year journeys.
