Mito - Workout Tracker

Mito is a private, offline-first workout tracker built for people who care about their training and their data.

No accounts. No ads. No analytics. No subscriptions. Your workouts live on your device — not on someone else's server.

WHAT IT DOES

• Track every workout — exercises, sets, reps, weights, rest times, notes
• Build your own routines or pick from a built-in catalogue of common exercises and full programs
• See progress over time with clean charts for your top lifts, total volume and body measurements
• Log body weight and key measurements (chest, waist, arms, etc.) and watch them trend
• Calendar view of your training history at a glance
• Audio rest timer that keeps the screen awake during a session
• Import and export everything as a single JSON file — your data, always portable

PRIVATE BY DESIGN

• 100% offline core. Logging, history, charts and timers all work with no internet connection
• No sign-up, no email required, no Mito account exists at all
• No third-party analytics, no advertising ID, no tracking SDKs
• No background data collection — Mito literally cannot leak data it doesn't have

OPTIONAL CLOUD BACKUP

If you want a backup, Mito can save an encrypted snapshot to YOUR own Google Drive in a hidden, app-private folder that only Mito can read. We never see it. Backup is off by default. You can delete it from inside the app at any time.

OPTIONAL AI COACH

Generate complete workouts from a simple prompt — “a 45-minute upper-body session with dumbbells”, “a 6-week beginner full-body plan”, “something to do at home with no equipment”. Refine the result in plain language until it fits.

The AI Coach is opt-in. Bring your own Anthropic Claude API key and your prompts go directly from your phone to Anthropic — Mito never sees, stores or proxies them. Disable the feature any time and your key is wiped from the device.

WHO IT'S FOR

• Lifters who want to log every set without battling a paywall
• Runners and hybrid athletes who want strength + cardio in one place
• Anyone tired of fitness apps that turn personal data into a product

DELETE YOUR DATA ANY TIME

In-app: Settings → Data & Privacy → Delete all data, or just uninstall the app. Full instructions at https://mitofit.ch/delete_data.html

ABOUT

Built by an independent developer in Switzerland under the name spatialsparks. The name “Mito” comes from mitochondria — the part of the cell that turns food into the energy you train with.
