About
Train for your first half-distance triathlon (1.2 mi swim · 56 mi bike · 13.1 mi run) without giving up the gym.
Pick your goal race and the app builds the plan backwards from race day, in phases: Adaptation, Base, Build, Race-specific and Taper. Choose 3 to 6 sessions a week or build your own routines: every week blends your usual strength split with swim, bike and run blocks — all doable in a gym with a pool and a treadmill.
A WORKOUT MODE THAT SURVIVES REAL LIFE
• Bulletproof session timer: lock the screen, switch apps or kill the app — your time is never lost.
• Per-set logging: reps and weight, with smart progression hints.
• Rest countdowns with sound and haptics, right on the Lock Screen too.
• Dynamic warm-up before lifting; guided stretching with per-side timers.
• Real cardio logging: duration, distance and incline, with pace and speed computed for you.
• 600+ exercises explained: 3D animation, muscles worked, step by step and common mistakes.
YOUR PROGRESS
• Training calendar with a completion ring on every day you trained.
• Charts for body weight, per-exercise load and muscle-group volume.
• Profile with BMI, heart-rate zones and weight goal.
• Apple Health sync: completed cardio is saved as workouts.
• Follow your session and log sets from your Apple Watch.
YOUR RACE
• Half-distance race calendar with dates and registration windows, updated without app updates.
• Registration alerts: 30 days, 7 days and on opening day.
• Add your local race to a calendar shared by every athlete.
• Race-day guides: nutrition, transition bags, open water and checklist.
• Home-screen widget with your countdown and weekly sessions.
No accounts, no ads. Your data lives on your iPhone and in your iCloud.
