Watchletic brings workouts from TrainAsONE to your Apple Watch or Wear OS watch.
Import your planned intervals, then follow each step and target from your wrist. When you finish, Watchletic saves the workout to Apple Health or Health Connect and can export it back to TrainAsONE.
You can also export GPX, TCX, and FIT files when you need them.
