Adopt a rock. That's it. That's the game. Your rock does nothing — and it does it perfectly. Pet it, feed it minerals it won't eat, polish it to a proud dull finish, and watch the Zen flow in as your rock sits there, unbothered, thriving. EARN ZEN BY DOING NOTHING Your rock generates Zen every second, even when you're away. It's not lazy. It's geological. DRESS YOUR ROCK Googly eyes. A tiny hat. Sunglasses for a sun it cannot perceive. A crown, because it earned it by sitting still. A friend pebble — they will never speak, and they are best friends. ACHIEVEMENTS Pet the rock 1,000 times. Reach Enlightenment. Own everything. History will remember none of it. RANDOM EVENTS A bird may land on your rock and pay rent. A snail may challenge it to a race. The rock will win by not entering. Just you and a rock, doing nothing together. Optional tips exist if you wish to thank the rock. It will display no gratitude. Warning: the rock does nothing. That is the point.
TamaShell
Read full descriptionHide full description
TamaShell is a virtual pet that lives entirely inside a fake computer terminal. Hatch an egg, then keep your pet fed, clean, rested, and happy using simple typed commands or on screen buttons. Your pet keeps living in real time, even while the app is closed, so a few days of neglect will actually catch up with you. Along the way there is a full day and night cycle, a coin economy you can earn by putting your pet to work, a shop for food and room decorations, and more... who knows what hides away in the terminal? If your pet dies, it does not just disappear. Reset and start the next generation. Raise a pet. Keep the terminal alive.

Verdict
The clearest difference is ads: TamaShell at none against PetRocky's shown. PetRocky's advantage is update cadence (every 2 days vs monthly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
