Good Rock: Adopt a Tiny Rock
Googly Eyes, Widgets & Tricks
$0.99 · Designed for iPad. Not verified for macOS.
Adopt a rock with googly eyes. Name it, dress it up, take it on walks. It needs nothing from you and loves you anyway. Probably.
Adopt a rock. Give it a name. It will never need feeding, walking or cleaning up after. It will simply be there for you.
Good Rock is the easiest pet you will ever have. Visit the Rock Shelter, pick the rock that speaks to you (it won't actually speak), and bring it home on its own velvet cushion.
PAT YOUR ROCK
Tap your rock to give it a pat. You'll feel a satisfying little thud. Tilt your phone and watch its googly eyes roll around.
TEACH IT TRICKS
Sit. Stay. Speak. Play Dead. Your rock is a natural at most of them. Roll Over takes patience. A lot of patience. But it can happen.
TAKE IT FOR A WALK
Tap Walk and your rock rides along on your Lock Screen and in the Dynamic Island, with a timer counting every minute of quality time together.
READ ITS DIARY
Your rock writes one diary entry every day. Most days: "Sat very still. Nailed it." Some days are big: it moved 1 mm. A ladybug stopped by. It grew a little moss.
DRESS IT UP
Top hat, beanie, party hat, crown, cowboy hat or a daisy. Add a mustache, glasses or a bow. Or keep it classic.
MAKE IT OFFICIAL
Every rock comes with adoption papers: its name, adoption date, temperament, and a life expectancy of about 4.5 billion years. Share them with friends.
KEEP IT CLOSE
Put your rock on your Home Screen or Lock Screen with widgets. Check in any time. It will be right where you left it.
SIX ROCKS TO CHOOSE FROM
- Granite: speckled, dependable, says very little
- River Stone: smooth from years of going with the flow
- Sandstone: layered personality, warm undertones
- Basalt: dark, mysterious, formerly a volcano
- Red Jasper: a little fiery, still does nothing
- Marble: fancy, knows it, stays humble anyway
Every rock is one of a kind. No two share the same shape or speckles.
