Just The Watts is an indoor cycling application intended to be used in tandem with a bicycle trainer, and speed, cadence, and heart rate sensors. You can use the estimated virtual power provided to create structured workouts to level-up your training.
To get the most accurate virtual power measurement possible you will need to go into preferences and select your trainer from currently supported trainers list. If you are using a trainer that is not currently listed, please contact us, and we will do our best to accommodate your equipment.
Just The Watts uses Core Bluetooth to track and display your speed, cadence, and heart rate as data fields while you ride.
