Couch To 10k

Couch to 10K is a structured, privacy-first running coach that takes you from your very first walk-run to a full 10 kilometre run in nine weeks.

Twenty-seven lessons. Three workouts a week. A clear path from the couch to the finish line — at your pace, on your phone, with your data staying on your phone.

HOW IT WORKS

Each lesson is a guided walk/run interval session. Press start, put your phone in your pocket, and let the audio cues tell you when to walk and when to run. The app counts down each interval, plays a chime at transitions, and a clear voice prompt tells you what's next. No need to look at the screen.

Across nine weeks you progress from short run/walk intervals to longer continuous runs, finishing with a full 10K goal run.

TRAIN OUTDOORS OR ON A TREADMILL

• Outdoor mode uses GPS to track your distance, pace, and route. After each workout, see your run drawn on a map in the History screen.

• Treadmill mode uses your phone's step counter to estimate distance — no GPS needed, perfect for the gym or rainy days.

Switch modes per workout. The app keeps tracking while the screen is off thanks to a persistent workout notification.

WHAT'S INCLUDED

• 27 progressively-structured lessons, 9 weeks • Voice-guided walk / run / warm-up / cool-down cues • GPS route tracking with map replay • Treadmill mode with step-based distance • Pace, distance, and elapsed time during workouts • Pause, resume, or skip intervals on the fly • Audio alerts and vibration at every transition (both togglable) • Metric (km) or Imperial (mi) units • Workout history with full route maps for every saved run • Foreground service keeps tracking when the screen is off • Works fully offline once installed

PRIVACY YOU CAN ACTUALLY VERIFY

Most fitness apps are advertising platforms. This one is not.

• No account required. You don't sign in. We don't know who you are. • No analytics, no tracking SDKs, no ads. None. • Your runs stay on your phone. GPS routes, distances, lesson progress — all stored locally in app-private storage and never uploaded. • The only thing we receive is anonymous crash reports (via Google Firebase Crashlytics) so we can fix bugs. They contain a stack trace, device model, and OS version — not your location, not your runs, not anything you can see on screen. • You can wipe everything any time from Settings → Delete my data.

Maps in the History screen are drawn using OpenStreetMap tiles, which means tile requests go to OpenStreetMap's servers when you open a saved run. That's the only other network traffic the app makes.

FREE AND PREMIUM

The first 5 lessons are free, so you can run more than a full week of training before deciding. A single one-time Premium unlock then gives you lifetime access to all 27 lessons.

No subscriptions. No recurring charges. No "premium features" hidden behind a second paywall later.

WHO IT'S FOR

• Total beginners who've never run before • Returning runners coming back from a long break • Walkers ready to add running • Anyone training for a 10K with a structured plan

Always talk to a doctor before starting a new exercise program.

PERMISSIONS WE ASK FOR

• Location — to track your route during outdoor runs (used only while a workout is active) • Activity recognition — to read the step counter during treadmill workouts • Notifications — to show the workout-in-progress notification

All permissions are explained in the app and can be revoked any time in Android settings.

Lace up. The first kilometre is the hardest. Let's get you to ten.
