The App can optionally connect to a heart-rate sensor to record heart-rate data alongside speed, stroke-rate and other recorded performance data. The App currently supports only one active heart-rate sensor at a time.

Supported Devices

Rowing in Motion supports any Bluetooth Smart enabled heart-rate sensor. In our experience, chest-straps work much much bettern than wrist-worn devices for rowing.

Your smartphone must support Bluetooth 4.0 and run iOS 8 or later.

Selecting a Heart-rate Sensor

When starting a session click on the heart-rate item to open the scan window. The scan window shows you all available heartrate-sensors and their signal strength.

If you see multiple sensors, try moving your sensor in direct proximity to your smartphone to identify it based on the strongest signal.


Most heart-rate sensors power up only when they detect a valid heart-rate signal. Put on your hear-rate sensor as per the manufacturers instructions and ensure the electrodes are sufficiently wet so that they can make proper contact with your skin.

You can select a heart-rate sensor by clicking on it.


Select None if you don’t wan’t to use a heart-rate sensor in your session. Otherwise RiM will constantly search for the last-selected hear-rate sensor and potentially drain your battery faster.

Rowing with a Heart-rate Sensor

During your rowing session, the App can display heart-rate data and record it for later analysis in Rowing in Motion Analytics. You can select the Heart-rate metric for display in any slot, see Customizing Data Display.


If you see a “-“” the App is unable to connect to your heart-rate sensor or it is not transmitting any data. If you see a “0”, the App is receiving data but the sensor is unable to record a proper signal. Try wettening the electrodes so that they can make better contact with your skin.

Should the App loose its connection to the heart-rate sensor it will automatically try to re-establish it.
