Stillbox

Box breathing & focus timer — for iPhone and Apple Watch

Patterned breathing you can feel. Distinct haptic textures pace every inhale, hold, and exhale, so a full session works with your eyes closed and your screen dark. Breathing sessions remain silent; optional ambient soundscapes live in their own library.

• Box, 4-7-8, and more — plus a custom pattern builder
• 42 original ambient soundscapes and music tracks, all bundled for offline use
• Streaks that survive reinstalls, on your own iCloud
• Widgets, Live Activities, and a standalone Watch app

No account. No ads. No developer data collection. Sessions stay on your device; only a small streak marker can sync through your private iCloud.

Coming soon to the App Store.
