About this app

Coxswain helps you organize your rowing: Connect your Android device to your Waterrower and choose your training program.

- record your workout while watching Youtube videos or other media (choose an intent to be executed on training start)
- row against previous workouts
- adjust the workout display (long press to choice from distance, duration, strokes, energy, speed, pulse, stroke rate, stroke ratio, time, split, average split, delta distance, delta duration)
- export your workout to TCX (Training Center XML) to import it into your favorite fitness tracking App or service.
- export your workout to your calendar
- export your workout to Google Fit (experimental)
- read heart rate from your Waterrower, Android sensor or a connected Bluetooth LE/Ant+ device

Your Waterrower S4 can be connected to your Android device
- either via USB-OTG adapter (USB-A-female to USB-micro/USB-C resp.), requires On-The-Go (OTG) support on your device
- or Bluetooth, requires the Waterrower S4 Bluetooth Comm Module (check the revision number printed on it, "S4 comms 36" is not supported)

This app is under development. Please report problems and ideas to https://github.com/svenmeier/coxswain

My must have waterrower workout tracker, which I use instead of the very basic S4 monitor. Would like more granularity on timings & distance (10" to allow 50"/10", and 50 m to allow 750m). Also review of segment timings and distances without having to dig into spreadsheets. But those are minor details compared to the huge flexibility and power this app gives you. For free! Minor issue - can't reconnect HRM to it after changing HRM battery, which is weird.

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

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.
