Adopt a rock. Give it a name. It will never need feeding, walking or cleaning up after. It will simply be there for you.

Can my rock die or run away?
No. Your rock needs no care at all. You can ignore it for a year and it will be exactly where you left it.
How do I add the widget?
Touch and hold an empty spot on your Home Screen or Lock Screen, tap Edit, then Add Widget, and search for Good Rock.
The walk doesn't show on my Lock Screen.
Open the Settings app, go to Good Rock, and make sure Live Activities is turned on. Then start a new walk. A walk ends by itself after about 8 hours.
Did my rock really move?
Sometimes it moves 1 mm. It's all in the diary. We don't know how it does it either.
Can I rename my rock?
Yes. Tap the gear icon on the main screen and change the name.
Can I adopt a different rock?
Yes. In Settings, tap “Return to the shelter”, then pick a new rock. The old rock's diary and stats are removed.
I can't hear the knock sound.
Check that Sounds is on in the app's Settings and that your phone is not set to silent.

Good Rock (“the App”) is provided by an independent developer (“we”). This policy explains how the App handles information.
We do not collect any personal information. The App has no accounts, no sign-in, no ads, no analytics and no tracking, and it does not connect to the internet.
Your rock
Your rock's name, outfit and stats are stored only on your device, so the App and its widgets can show them.
Motion
While the App is open, it reads your device's tilt so the googly eyes can roll. This happens only on your device and is never stored or sent anywhere.
Purchase
The App is purchased through the App Store. Apple processes the payment, and we do not receive your name, email address or payment information. Please see
Apple’s Privacy Policy for details.
If you share your adoption papers, the image goes only where you choose to send it.
We do not collect, store or share any personal information from anyone, including children under 13.
Deleting the App removes your rock and all of its data from your device.
We may update this policy when the App changes. Updates will be posted on this page with a new “Last updated” date.
