Works well as a tracker, leaves much on the table

As others have mentioned, the app does well at what it says it will do: namely track and upload workouts. From a user experience, the ease of connecting via Bluetooth and the landscape limitation needs significant improvement.

The landscape mode in particular keeps this from being an app that is more useful. It is impossible to create an account in-app for example - solely because Input in landscape mode is hindered. When not not connected to an erg via Bluetooth, the layout should switch to portrait to present and interact with data. These intuitive design (non) choices are just a few examples of why users say this app is stuck in the past.

Because Bluetooth connection is the primary connection to a PM5 with said capability, this feature should be prominent. Instead it is buried and difficult to interact with in the UI. All of that leads to frustration when hands are sweaty and muscles engaged from a workout, in on the midst of one.

Apple Watch integration of heart rate data would be a nice to have in a future release, as would additional Apple Watch features.

Useful & cool extension of PM5

First, I would like to say that I’m glad concept2 is more focused on making the best, most durable erg out there rather than being a tech company creating a fancy app. This app expands on what the PM five will show about each stroke and it easily syncs up with the online logbook. Very useful!

I don’t understand why all of these complainers think this app should be more than what it is. It seems like there are plenty of 3rd party apps to choose from. I haven’t tried those other rowing machine apps yet, but I don’t need to and don’t want to, especially if they include ads which this app does not—thankfully. If you want a cool extension of the PM5 and an easy way to sync with your online logbook, this is the app for you.

The best at no-play logging

The combination of the easy interaction with the PM5 and enhanced data logging on the Concept 2 site make this the most useful real training app I’ve used. It connects easily via Bluetooth, and accurately tracks the workout without the glitchiness of some. It syncs quickly with you C2 account and provides full data on your workouts, so you can get spreadsheet or graphical views of your work. ErgData is the perfect data link between your C2 rower and C2 account, giving you truly useful and meaningful logging and information that you can apply to evaluate every workout to see if you’re progressing to your goal. That’s what it was designed to do, no frills, and I like it that way.
