Does Watta work with the Concept2 SkiErg?

Yes. Watta fully supports the Concept2 SkiErg. The AI-powered OCR reads PM5 screen data from SkiErg sessions, capturing split time, distance, stroke rate, and calories.

Can I track SkiErg and RowErg in the same app?

Yes. Watta tracks all three Concept2 machines — RowErg, SkiErg, and BikeErg — in one unified app. Each workout is tagged by machine type.

Is the Effort Score calculated differently for SkiErg?

The Effort Score uses the same core algorithm across machine types, with adjustments for the different physiological demands. This gives you a consistent intensity metric regardless of which Concept2 machine you use.

Finally, a proper tracker for your SkiErg sessions

By the Watta Team · Updated March 2026

The SkiErg deserves dedicated tracking. Watta captures your PM5 data with a single photo — split time, distance, stroke rate, and calories. Get Effort Scores for every ski erg session, track your progress, and share with your community.

App for SkiErg Users: 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

SkiErg is the forgotten Concept2 machine

Most fitness apps and rowing communities focus exclusively on the RowErg. SkiErg users are left without dedicated tracking, forcing them to use generic workout logs or spreadsheets.

No way to compare SkiErg sessions meaningfully

Without an intensity metric designed for SkiErg, comparing a 20-minute steady session to a 10-minute interval piece is subjective. Users lack a standardised way to quantify session quality.

SkiErg data is not captured alongside rowing data

Athletes who use both RowErg and SkiErg want their training in one place. Most apps treat them as completely separate activities with no unified view.

How Watta Helps

🎿

SkiErg OCR Logging

Photograph your SkiErg PM5 screen and Watta extracts split, distance, time, and stroke rate. The same AI-powered logging that works for rowing, adapted for ski erg.

📊

Unified Erg Dashboard

View your SkiErg, RowErg, and BikeErg workouts in a single feed. Filter by machine type or see everything together. One app for all your Concept2 training.

🎯

Effort Score for Ski Erg

Every SkiErg session gets a 0-100 Effort Score. Compare intensity across sessions and machine types to manage your overall training load.

How It Works

Snap your erg screen

Take a photo of your PM5 display after your workout. Gallery upload works too.
