Made for a penguin fan

Nidus Pets started at home. We wanted to give a young penguin lover in our family a penguin of his own: one he could look after, play with and come back to every day. So we made him one. Now everyone gets a mystery egg of their own to raise.

A pet that lives in real time

Nidus Pets is a digital pet in the classic style. It gets hungry while you're at work, sleeps when you sleep, and calls for you a few times a day. Every egg is a mystery: its species is decided by how you raise it, and its job decides how it evolves.

When it grows old, it retires to Haven, a little town built by every pet you've raised.

On your wrist, too

A full Apple Watch app that stays in sync with your iPhone. Check in, feed it, or play a quick game without reaching for your phone.
