See every athlete's erg data in one place

By the Watta Team · Updated March 2026

Rowing coaches need erg data from every athlete, every session. Watta makes it automatic — athletes photograph their PM5 screen, and their workouts appear in your squad feed with splits, distance, stroke rate, and Effort Scores.

Rowing App for Coaches: 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

Collecting erg scores from athletes is a battle

After every training session, coaches chase athletes for their erg splits via text, email, or whiteboards. Scores get lost, misremembered, or never reported. Building a reliable training database is nearly impossible.

Spreadsheets do not scale

Most rowing coaches track erg data in spreadsheets. With 20-60 athletes logging 5-10 sessions per week, these spreadsheets become unmanageable within a single season.

Limited visibility into training compliance

During off-season or when athletes train independently, coaches have little insight into whether prescribed sessions are being completed and at the right intensity.
