霧 Fog: Most of it never happens.

A worry tracker that brings your worries back later, so you can see which ones came true.

Write a worry down. Seal it. Pick a day to look again. When the day comes, Fog asks one question: did this happen? Your Fog Score keeps count of how many never did.

Everything stays on your phone. No account, no servers, no tracking. Available in English, Japanese and Korean.
