Raise a Marimo in your phone

Features & Capabilities

The Marimo is a charming virtual pet Chrome extension that lets you raise a moss ball on your device. With over 1,110,000 downloads, you care for your Marimo by refreshing its water when it gets dirty and keeping it in a bright place for photosynthesis, so it grows little by little each day.

Interact with your Marimo through gestures: rename it, change its background, drag to move, double-tap to pick up, and rotate with two fingers. It responds to the direction of your device and you can share Marimo images to Twitter or Facebook.

User Reviews

Today marks the 1825th day my Marimo is years old. It's moved across two phone upgrades. There's no reason to really have this app, but I've gotten endeared to it. 10/10. Hope this app never dies so I can keep transferring up and show my grandkids my digital moss ball that's older than them.
