Worry Stone

Hold a stone, then see how your thumb motion settled — time-to-stillness and a curve, measured on-device.

Worry Stone is a tactile pocket ritual for quiet moments. Rub a digital stone, feel haptic texture, choose from crafted stone surfaces, and keep private notes about moments you want to remember.

Version 1.5 adds Settling Curve: after an eight-second hold, the app measures how your thumb motion slowed, when it reached stillness, and which stone settles you first. The read is motion-only. It is not a mood score, a health metric, or a clinical tool.

The app is designed around small, intentional use:

• Settling Curve — on-device motion analysis of each hold, with a curve, time-to-stillness, and a ranking of stones
• A tactile stone surface with haptic feedback and subtle wear that builds over time
• Ritual Planner for choosing a short local plan from your intent, time window, and energy
• Guided breathing patterns with animated stone expansion and optional timers
• Reflections with private moment notes, local trends, streaks, and stone history
• Stone drawer with 20 hand-tuned stones across smooth, glossy, translucent, pitted, and beaded textures
• Lore cards, giftable stone files, share cards, local backup/restore, widgets, and Live Activity support
• Ambient sound options and daily reminders you can enable or leave off

Everything is local-first. Your notes, history, settings, gifts, backups, measured holds, and planner choices stay on your device unless you choose to export or share them. The app does not require an account, location, camera, contacts, or a network connection for its main features.

Worry Stone is a lifestyle and reflection tool for personal journaling and tactile interaction, not for clinical or emergency use.
