    I use this to convert my phone into a speed coach on the water, and to easily log my erg workouts. Great app!

    The upgrades are worth the money. Very easy to program a workout. Wish I could rate it 10 stars.

    Good improvements over time. Chat in rowing with friends should be improved, but I know it is a very recent addition. Using PM3, Polar H7, Nexus 5 (Lollipop).

    This app has really made the erg c2 pm3 even better ... I really enjoy using the erg for cross training and this app has helped me push harder with a more consistent stroke... The developer has been really responsive and clearly answered my questions...its worth the money to me... It syncs my workouts to the c2 site and now the polar h7 hrm works with the erg...

    Outstanding and useful app. Developer is great at following up and making tweaks to an already awesome app.

    Exactly what I'm looking for in a rowing app. Icing on the cake would be to add Bluetooth functionality to pair the phone wirelessly to the PM5 new version 17 update. Dev: I am happy to beta test :) Nexus 5 user here

    Somehow logging (log book) does not work (does not record workouts) with PM5 (firmware version 12). Couldn't figure it out, with PM3 everything's fine...?
