Make every campus gym erg session count

By the Watta Team · Updated 10 August 2026

University gyms are full of Concept2 rowing machines — and students who have no idea how to use them effectively. Watta turns your erg sessions into structured training data with AI screen capture, teaches you what your numbers mean with the Effort Score, and connects you with friends for motivation.

Rowing App for University Students: 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

No idea what the erg numbers mean

Most university students hop on a rowing machine without understanding split time, stroke rate, or drag factor. They row for 20 minutes, feel tired, and have no idea whether the session was effective or how to improve.

Motivation drops without social accountability

Going to the gym alone during exam season is hard enough. Without friends to train with or a way to share progress, erg sessions become boring and inconsistent.

Free apps are limited or confusing

Students want free tools — but free fitness apps either lack rowing-specific features or overwhelm beginners with jargon. There is no free app that makes erg tracking simple and educational.
