Built for real family life
No lengthy setup. No account. Just open the app and head outside.
Weather-smart suggestions
Every nudge is tailored to your actual conditions — sunny afternoon adventures differ from drizzly morning ones. The app reads your local forecast so you don't have to.
Fits your gear
Tell Underpebble what equipment you have on hand and it filters adventures to match — bikes, magnifying glasses, rain boots, or nothing at all.
Build your streak
Track how many days in a row your family chooses the outdoors over a screen. A simple streak turns a daily nudge into a lasting habit — without the pressure of a fitness app.
Timed or open-ended
Some adventures fit in 10 minutes. Others fill a whole afternoon. Each nudge shows a suggested duration and includes a built-in timer so you can stay on track.
Private by design
Everything stays on your device. No account, no cloud sync, no ads. Your family's adventure history is yours alone.

Questions, answered
Everything you need to know before your first adventure.
Does Underpebble require an account?
No. There's no sign-up, no email, no password — just open the app and get your first adventure nudge.
Is my family's data private?
Yes. Adventure history, streaks, and settings are stored only on your device using encrypted local storage. There's no ad tracking and no cloud sync.
What ages is Underpebble good for?
Underpebble works for families with kids of any age — nudges adapt in complexity based on the ages you enter in Settings.
How does Underpebble decide what to suggest?
Each nudge factors in your local weather, the time of day, and the equipment you have on hand — no planning required.
Is Underpebble free?
Yes, it's free to download and use on iOS and Android, with no account required.
Does it work without location access?
Yes — if location isn't enabled, you'll still get a fresh daily nudge; it just won't be tailored to real-time local weather.
