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.

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

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. See the report below.
