Tempus, btwb’s most ambitious endeavor, is a revolutionary addition to the daily workout experience. It’s a new level of workout tracking combined with an ecosystem that will give you deeper insights into your fitness journey. It will also help connect you to your workout partners and fitness communities in ways you’ve never imagined.


At its core, Tempus is a built in workout timer that allows you to perform workouts and log scores all from inside of the btwb app. However, this isn't just your typical workout timer...


  • Race against your past performances in realtime
  • Perform garage workouts live against friends
  • Display athlete participant progress on a screen during the workout
  • Capture rounds splits and movement splits and save them automatically


Use Tempus via your mobile phone. 


Or via Apple watch.
