I'm a beginner rower and the S4 is too sophisticated for me at the moment. Found this app, figured it out in 3 minutes, created an interval workout, plugged my phone into a USB hub and the hub to the S4. Started rowing my workout and the voice guide was gold! Exported the results to Google Fit no problem. If developer wants to create a donation link, would readily thank him. Much appreciated!!

Works well for me, and integrates well with waterrower S4 functions. If being picky I'd say it would be helpful to have granularity to ten seconds, rather than thirty seconds, and have the voice coaching the same, rather than to the nearest minute (annoying if you're doing 1'30" pieces). Also it would be useful if the distances for each set were logged. For example, if I'm doing 3' on, 3' off x6, I'd like to review the distance for each firm 3' once I've finished, and be able to target distance during the set (ie beat or maintain previous distance). The overall distance, including the recovery time, is completely unimportant. I appreciate that feeding the data into a spreadsheet can pull it out, but it would be nice to do in app, and doesn't help during the session. Or for 6x500m, present the time for each preceding 500m as I do them, and this should be stored for review and targeting. But a solid piece of kit, and a great training aid that is pretty much compulsory for waterrower owners that are training to improve on the water performance, in my view.

Great for darkly lit room or people with poor eyesight. Keep up the good work. I'd be happy to pay for it.

I'm a relative newbie to rowing but an otherwise self-motivated garage gym trainer mostly doing strength training and since rowing isn't my main focus this app is ideal to guide/bully/motivate me to get the work done (the spoken instructions and sounds are excellent for this). Example: I'm typing this having literally just finished a workout where I started off thinking "nah, not today, I'll stop in at the next..." instead, thanks to this app, I improved my time and stroke efficiency over the last workout.

Great app

Super functional and makes rowing more fun and easier to track. The Google fit integration is awesome but it should sync up automatically without having to manually export. Overall the interface could use some polish but functionally it's 5 stars.

Definitely the easiest way to log workouts with the waterrower. Very reliable app

Very useful for planning and recording workouts, I always use it. There's room for improvement but it deserves 5 stars for how much I rely on it.

Great app, finally one that works well with Waterrower S4 and records workout data in detail. Hope the app well get more functionality in the future.

Now it seems it's getting nicer

Terrific app for use with an S4 monitor. Keep up the good work!

Great app with steady fast paced improvements. Would love more analysis functions. Like plotting of power during pull (see Concept2), average power output during workout etc. I am using it in every workout since I discovered it.

Love it. Great to have something that works with a waterrower. Would love a pace boat but looking forward to making good use of this app. Thanks very much.

Been using this for about a week and I am impressed! It's great as is but I'm looking forward to future improvements.

Great!

Sven has responded very quickly to user suggestions. Communications with his users is exemplary.

Works like a charm with no issues. Would be great if there was a workout report or chart that you can see your progression with.
