Review summary

Users find ErgData useful and growing more reliable, with strong support and improved battery performance after updates. However, multiple users report ongoing battery drain for some scenarios, workouts failing to save or record, and syncing/logbook/API issues. Occasional regressions after updates also affect compatibility and features. Overall, the app is valued for workout tracking and integration, but stability and data-synchronization concerns recur across reviews.

Pros

Very helpful app for maximizing use of C2 ERG equipment and convenient workout/data tracking.
Generally reliable and improves over time; users report it works great and has come a long way.
Responsive support and quick issue resolution from the developers.
Recent updates have addressed battery drain, restoring better battery life.

Cons

Battery drain remains an issue for some users, especially after updates.
Workouts not saving or data not recorded due to disconnects or crashes.
Data syncing with Garmin Connect and logbook issues, plus API/data handling problems.
Updates can cause regressions or compatibility issues (e.g., breaking features or device compatibility).

2026-06-22	Di*****	I put off getting this app based on all of the bad ratings but now I wish I had downloaded this sooner. It has worked flawlessly for me with 6 workouts logged so far. I have been rowing for 3 years and recently I have not been enjoying it as much as I used to. When looking to shake things up, I found the workout of the day (WOD) and decided to try it. The app lets you skip all of the manual workout programming and sparks my competitiveness by showing how my performance compares to others.

2026-06-14	Mr*****	So far so good.
So far so good.
2026-06-07	Ti*****	Works reasonably well. Improvements: - Should save sessions by default, else sessions are lost if you forget to 'save' them at the end. - Displays 'cal' as a unit in the session summary. I think that should be 'Cal' or 'kcal'?
