03 — Habits

Habits that add up, guilt-free

What sustains progress: sleeping, eating, training consistently. No rigid streaks that break — 5 out of 7 is already a great week. You choose what to track and how often.

Why Myosin

Built for serious training

01
Everything in one app
Training, progress, habits and calisthenics. No jumping between five apps that don't talk to each other.
02
100% local-first
Works perfectly offline. Your data lives on your phone and syncs on its own — it's yours.
03
No ads, no noise
The app doesn't sell you anything or interrupt you. Get in, log, get out.
04
Automatic PRs
You don't log records by hand. Progress is detected on its own and shows up when you hit it.

your progress.
