ErgData is a free iOS application designed to run on an Apple iPhone or iPod touch. For full use, ErgData requires a connection to a Concept2 Indoor Rower, BikeErg or SkiErg. This may be either a wireless connection to a Concept2 PM5, or a special cable for PM3 or PM4. Once connected, ErgData provides additional statistics, stores and displays your workout results, and uploads your workouts to the Concept2 Online Logbook. It also offers the enhanced visibility of a backlit display.

- Concept2 Indoor Rower (any model), SkiErg or BikeErg with PM3, PM4, or PM5 monitor.
Note: Updating the firmware (software) in the PM3, PM4, or PM5 may be required.
- iPhone 4S or later, or an iPod touch 5 or later. iOS 9 or higher.
- If using a PM3 or PM4 a cable may be available from liverowing.com
- If using a PM5 then a connection may be made using Bluetooth Smart instead of a cable. A firmware update to the PM5 may be required for all Concept2 Indoor Rowers and SkiErgs shipped before Jan 1, 2015.

Love my Rower...App not so much

I am fairly new to indoor rowing and love my C2 rower. The app is fine for why I got it. I use it to upload my row data to my online logbook but being new to rowing I wish it could offer tips on improving my sessions based on my results. I’ve been looking online to better understand what all the numbers mean but it would be cool if I could get the info from the app. I would love if this would work with my Apple Watch too; depending on where I have my rower sitting I sometimes have to set my phone in odd spots so using it on my watch would be awesome.
Sadly the app doesn’t represent the Concept2 brand as well as it should but it’s a good basic app.

Like The App for Rowing

This app works well with the PM5. It connects right away after turning wireless on with the PM5 buttons, displays live in data on the phone so I can see more stats at once. The app also exports to Apple health automatically which is very convenient. My calorie counting app automatically imports from Apple health so tracking workouts is automatic. The app also corrects for user weight in the calories burned estimates so I don’t have to manually convert!

The app interface is very simple with no real time plotting or racing. Just a display, logger, and auto sync to Apple health. Syncing to C2 logbook is manual but quick.

4/5 stars.

Needs a serious update

I have 3 Concept2 ERGs (rower, ski, bike). If Concept2 wants to maintain its reputation it needs to recognize that a good app is a minimum requirement to provide the kind of value your customers want. This app doesn’t qualify. Here are some of the things missing. 1. A portrait mode. It is incredibly annoying. 2. Explicit and serious support for the BikeERG. 3. An Apple Watch app. There are more but I will stop there for now. We’re in a connected world and the PM needs to make that connectivity seamless. This app is the closest thing to enabling that but it’s other flaws make it too annoying to use. Charge for it if you have to. Or, make a “pro” version that you charge for. Please just make it better.
