Rytmo

Rytmo is a fitness habit tracker built around one idea borrowed from Atomic Habits: the goal isn’t the workout, it’s becoming someone who shows up.

Set up your routines once — warm-ups, circuits, intervals, whatever shape your training takes — and Rytmo gives you a clean dual-mode stopwatch. Green for work, amber for rest. Tap to switch. Let the rhythm find itself.

Every session earns XP. Twenty levels climb from Rest all the way to Rytmo, with 25 achievements tracking the things that actually build a habit: streaks, consistency, variety, time under effort. No algorithm telling you what to do — just a record of what you’ve actually done.

Fully offline. No account. Free.

Features

Built on Atomic Habits

Small sessions, consistent rhythm, visible progress. Rytmo is designed around the idea that showing up matters more than going hard — and that what gets tracked gets done.

Build the habit

Track your daily training, week over week. See what you stuck with and what slipped. The streak is the point.

Dual-mode stopwatch

Time the work and the rest in one tap. Green is active, amber is recovery — switch with the same button.

Twenty levels, twenty-five achievements

Every session earns XP. Climb from Rest to Rytmo across 20 levels, and unlock 25 achievements tracking streaks, cardio, mindfulness, session length, and more.
