Pets OS 1.3.0
A phone that’s
on your side.
Pip keeps you company. Clarice helps without sending your life to the cloud. And everything you do stays on your phone.
Only on Pets OS
Things no other phone does.
Pip, your pet
Pip lives on your Home Screen, gets hungry, wants to play, and is genuinely happy to see you.
Pip Walk
A focus timer: Pip goes for a walk while you focus. Open a distracting app and Pip looks back, sadly.
Time Capsule
Write to your future self. It stays sealed until the day you choose, then Pip brings it to you.
Day Story
In the evening, Clarice tells the story of your day from what’s on your phone. Nothing leaves it.
Pip Guard
Wrong passcode? Pip barks. After you unlock, Pip tells you how many tries there were, and when.
Wind Down
At bedtime the screen turns warm and dim, and can go grey, to make putting your phone down easier.
