Watchletic connects workouts from Apple Watch and Wear OS to Runalyze for detailed endurance analysis.
Record a run, ride, swim, walk, or cross-country ski workout with Watchletic, then export the completed session to Runalyze as a FIT file.
Enable auto-export and Watchletic can send supported completed workouts automatically after the session, so your Runalyze history stays up to date without manual file handling.
With a compatible Bluetooth heart-rate monitor that sends R-R intervals, Watchletic can record live DFA-a1 and include raw R-R intervals plus DFA-a1 data in FIT exports. That makes Runalyze a strong destination for post-workout HRV and aerobic-threshold analysis. Read the DFA alpha 1 guides for Apple Watch or Wear OS.
Runalyze can also receive optional readiness data from Watchletic, including HRV, resting heart rate, and sleep, when you connect the integration and grant those permissions.
