Virtual Cycling Trainer

Version History

1.4.0

  • Customizable workout layouts on iPhone and iPad: build your own ride screen — choose the stats you care about and arrange them just the way you like.
  • Many more stats are now available to place in your layout, including current, average, and peak power, cadence, heart-rate metrics, active and total energy, and time in power zones.
  • Added support for body temperature sensors: connect a compatible Bluetooth sensor to track core and skin temperature plus heat strain during workouts — great for heat training.
  • Trainer controls (ERG, Resistance, and Slope) are now more responsive and accurate — your adjustments show instantly and no longer snap back to the trainer’s reported value while you’re changing them.

  • Workouts now save average and maximum speed to Apple Health.

  • Improved automatic reconnection when your trainer drops the connection, turns off and on again, or changes its Bluetooth identity.
