## What is Worry Stone AI?

When your mind won't stop, give your fingers something to do.
Slide across the stone's grooves with your fingertip. Every ridge answers with a real haptic buzz. Slowly, your attention comes back.
No willpower. No sound. Just your finger and a digital stone.
It's not a timer — no alarms, no pressure.It's not a meditation class — no chanting, no forced silence.It's something to hold onto the moment your mind starts to race.
Touch Focus: trace the grooves and watch your focus bar rise.Breathe Mode: a glowing ring expands as you inhale, shrinks as you exhale. No headphones needed.Flow Mode: keep touching, and the app fades back — just a soft buzz stays with you.
Before sleep, before a test, before that big meeting — just reach for it.
Your focus never left. You just needed an anchor.
For relaxation and focus practice only. Not a medical device.
