About

Ritmo

Features
Read full description

A smart timer that guides you through every step. Most timer apps just count down. Ritmo walks you through what to do, how long, and what's next — with haptics and audio cues so you can close your eyes, put the phone down, or keep your hands on the pan. Tell Ritmo what you need — a Pomodoro sprint, a 4-7-8 breathing session, a perfect steak — and the AI builds the full step-by-step routine in seconds. Routines for: - Breathwork — box breathing, 4-7-8, coherent breathing - Focus — Pomodoro sprints, deep work blocks - Mindfulness — short grounding sessions, body scans - Cooking — steak, eggs, pasta, sous vide, anything with timing - Eating — slower, calmer meals - Anything else — describe it, the AI builds it A few things we got right: - Every step has its own duration, instruction, and cue — not one long beep at the end - "Up Next" preview so you're never surprised mid-flip - Haptics and audio that actually work eyes-closed or hands-busy - Live Activity and Dynamic Island support - Timing stays accurate even if you switch apps - No streaks. No leaderboards. No nagging notifications. No ads. Pro Unlimited AI-generated routines for $4.99/month or $29.99/year. 3-day free trial. - Charged to your Apple ID at purchase confirmation - Auto-renews unless cancelled at least 24 hours before the period ends - Manage or cancel anytime in your Apple ID settings Privacy We don't sell your data.
