Concept2 suggests looking at ErgData App which now includes voice features for visually impaired, works with PM3 and PM4, and does not require Wahoo Key. Concept2 understands that ErgBuddy provides some advantages for some customers, so it will remain in the iTunes app store until June 1, 2014.

ErgBuddy displays performance data from your Concept2 Indoor Rower providing a large, bright display which is particularly useful when rowing in a dimly lit or dark room.

Fully compatible with the iOS VoiceOver feature, ErgBuddy can also announce your performance data at regular intervals, making it an ideal training partner for the blind and visually impaired.

IMPORTANT NOTE: To use this program, there are some system requirements:
1) Wahoo Key (formerly "Fisica Sensor Key").
2) Concept2 rowing machine with PM4 monitor. Any rowing machine or PM4 monitor purchased before December 2012 may require a free firmware update to the PM4 monitor.

See for more detailed information.

If you cannot connect your PM4 to ErgBuddy, you may need a firmware update. Contact if you need assistance.

History of ErgBuddy: This project was started as a demonstration to show that it was possible to connect an iOS device to the PM4 and was shown at CES 2011. Visually impaired customers gave Concept2 feedback that this was an important development as the results could be spoken. As a result, Concept2 expedited the publishing specifically for this market. ErgBuddy is a low-frills free app specifically for this market.

Poor SW design and integration

This app looks circa 1980s. Yes, its nice to have a chart to look at, but why can’t it be more like RowPro? What about HeartRate? integration to online log book?
Can the C2 folks please hire a competent software engineer or outsource this development. Truly disappointing.
I also paid to get the iPhone connector kit and it did not come with a lightning cable. Apple switched over a while ago to lightning. They told me to go buy an adaptor ($30) to make this work.

Great app! Very useful!

The combination of the app, the connection kit, firmware updates to the PMx and the iDevice offer compelling new features. Leveraging the backlit screen allows rowing in the dark (simulates those early moring on water experiences), and the new exposed data elements are useful for developing better understanding of your performance.

For me, the top enabled new feature is the direct capture and syncing with the online logbook. This allows me to use public ergs while travelling without bringing my shared logcard from home or taking camera phone pics of the monitor screen! I simply can use the direct sync feature from the app.

NOTE - do not insert logcard into monitor when using this app as noted on concept2 web.

Forget it for PM3

No longer works with PM 3 monitors, so I wasted my money for the cable. Used to be great, but I'm not forking over the money for a new monitor just so I can use this software. Back to jotting numbers down on a tablet and manually entering data.
