Product overview
Local-first by design
Workout plans, exercises, history, and settings stay on the device. No registration and no backend are required for core use.
Built for the gym floor
Large controls, planned sets ready to confirm, rest timing, and technique notes when you need them — minimal friction between sets.
Your own exercise library
Create exercises with equipment details, photos, instructions, muscle notes, and optional video links or offline copies.
Plans, sessions, and progress
Build reusable plans, run active workouts, review history, and track working-weight progress over time.
Backup without a cloud account
Export and import exercises and plans as a JSON backup file. History stays local unless you choose what to share.
Prepared for distribution
