SmartRow is the first calibrated power meter used in a rowing machine. The electronics inside use sensors for force and displacement and calculates all the important rowing data. It continuously updates this data via Bluetooth to the SmartRow-app (available for iOS & Android).
SmartRow does what it promises, it measures applied power accurately, no matter:

• What kind of brand you use;
• What the recoil force of your rower is;
• What the friction in your rower is;
• What your stroke frequency is;
• How you accelerate/decelerate;
• How much water you have in your tank;
• How your damper is set.

For all these reasons, any comparison with the readings on your existing monitor falls short. For more information check these scientific articles:

To determine how accurate the SmartRow is, we have asked the Faculty of Human Movement Sciences of the University of Amsterdam, to research the validity of the SmartRow technology.
