Black Stone

Throw your heavy feelings away with a black stone. No records kept.

"Black Stone" is a small app for letting go. Place the feelings you cannot put into words onto a black stone, and throw it into a quiet spring deep in a cave.

Touch the stone, and it slowly slides into the water, disappearing with a splash. That is all. And sometimes, that is enough to make your heart a little lighter.

[How to Use]
1. Touch the stone. It slides away into the spring.
2. Turn on Drawing Mode to write or draw on the stone with your finger. Write the words you want to erase, then tap the Throw button. What you wrote sinks with the stone and disappears.
3. Choose from three effects for the moment the stone vanishes: Purify, Burst, or Big Burst.

[Safe and Quiet]
1. Completely free. No purchases, no ads.
2. Nothing is recorded. The app does not remember what you wrote or what you threw. No data is collected, and nothing is sent anywhere.
3. Works offline. Use it anywhere, even without a signal.
4. Sound is off by default, and vibration is optional. Safe to use late at night.
5. Available in 14 languages (Japanese, English, Arabic, Bengali, German, Spanish, French, Hindi, Indonesian, Italian, Korean, Portuguese, Russian, and Chinese).

[For the Nights You Keep Throwing]
If you find yourself throwing stone after stone, your heart may be very tired. On such a night, this app will gently speak to you, just once. It will show you places where someone can listen, such as support hotlines in your country. You do not have to talk. Then the app quietly returns to being a stone.

This app is made by "Soyogi", a non-profit consultation service for care and support in Japan. May it help you breathe a little easier when you carry feelings you cannot tell anyone.
