Caliber vs Hevy

Caliber is a strength training and coaching app offering over 60 structured training plans built by coaches, alongside unlimited custom workout creation for solo training. It scores users on metrics like a 'Strength Score' relative to their potential and 'Strength Balance' across muscle groups, and pairs the self-guided app experience with optional in-app coach messaging, video form reviews, and nutrition and habit tracking synced with Apple Health.

Hevy is a workout tracking app for logging strength training sessions, building custom routines, and monitoring progress over time through charts, personal records, and estimated one-rep max calculations. It also includes social features so users can follow other athletes and share workouts within the app's community.
