## What is KOKEMUSU?

Call the rain and set your phone down. Your moss grows. That is KOKEMUSU.
The apps that pull you in stay locked until the rain stops.
It turns the time you spent on your phone into a quiet moss garden, for focus and for rest.

HOW IT WORKS
• Call the rain ― choose how long it falls, and your time away from the phone begins
• Moss grows ― the longer it rains, the more it spreads, and you see the new growth on your pot when it stops
• Apps lock ― only the ones you choose, like social media and video
• Rainwater collects ― 1 cup for every 10 minutes, to trade for new vessels and mosses

KEEP IT GOING
Call the rain every day and earn a red seal at 3, 7 and 14 days in a row, and beyond.
Every 7 days you also earn a rain shelter, which keeps your streak alive through a day you miss.
Look back each week on how long you set your phone down.

COLLECT
Plant many kinds of moss in many kinds of vessels.
Name each pot, grow it, and place it in your moss book once it is fully grown. The mosses and vessels you find fill the book like a field guide.
More mosses and vessels are on the way.

A GARDEN TO LOOK AT
Beautiful, relaxing music and the view of a moss garden in the rain.
Stand your phone on the desk and focus on study or work while you watch.
