RowCraft vs ErgData
Concept2's official companion app for PM5 data logging.
ErgData is Concept2's official companion app — the one most rowers install first. It connects to your PM5 via Bluetooth, displays real-time data, and syncs workouts to the Concept2 Logbook. RowCraft also connects to the PM5, but takes a different approach: instead of just recording data, it provides structured workouts with pace targets and multi-week training plans. Both apps are completely free. Here's how they compare.
Feature Comparison
Where ErgData Shines
- As Concept2's official app, ErgData has the deepest Logbook integration — your workouts sync natively and appear as verified entries.
- ErgData supports Strava and Garmin Connect export out of the box, which RowCraft does not offer yet.
- Apple Watch support lets you see heart rate data on your wrist during workouts.
- If you just need to log meters and sync to Concept2, ErgData does exactly that with zero setup.
Where RowCraft Shines
- RowCraft includes 130+ structured workouts and multi-week training plans. ErgData is a data logger — it records what you do but doesn't guide what to do.
- Every RowCraft workout has FTP-based pace targets shown as minutes per 500m, so you know exactly how hard to pull for each interval.
- RowCraft's workout builder lets you design intervals with specific work/rest durations, target intensities, and stroke rate guidance — not just basic time or distance intervals.
- RowCraft has a full web app for browsing workouts, building custom sessions, and managing training plans from your computer.
The Verdict
ErgData is the best free data logger for Concept2 rowers — it does one thing well. RowCraft is for rowers who want structured training guidance on top of data logging. If you already know what workout to do and just need to record it, ErgData is great. If you want someone to tell you what to do and keep you on pace, that's what RowCraft is built for. Both are free, so there's no reason not to try both.
