Your Waterrower S4 can be connected to your Android device

- or Bluetooth, requires the Waterrower S4 Bluetooth Comm Module (check the revision number printed on it, "S4 comms 36" is not supported)

Ratings and reviews

Been using this for about a week and I am impressed! It's great as is but I'm looking forward to future improvements. Update Oct 2020 Month after month this app is the most seamless and most helpful tool for getting the most out of my waterrower. The connections (bluetooth and usb) from my phone to my HRM and to the S4 monitor on the rower are easy to establish and trouble free. After getting so much from it, I want to thank the developer for this fantastic contribution to the waterrower!

One of the best apps to pair with a WaterRower. I'm new to ERG, but this has really help me in setting up my training routine. Exporting the data to a site such as Rowsandall it's amazing to see just how much information can be extracted from each session. I use the Bluetooth command module from WaterRower to connect to the app and an ANT+ adaptor to connect to my Wahoo HR monitor. Once they are setup the app connects to both simultaneously.

Workout finishes unexpectedly and I have to restart it. It happened 3 times after I installed the app. I had planned to do 45' workout with intervals, and the app decided to finish it after ~1000mts (that was not the segment I had programmed). No reason, I cannot find any help file to check if there is a configuration set that is causing this. Liked the app, but is not giving me good results
