Sit is the meditation timer that can see how still you truly are. No guided voices. No streaks to chase. No cloud accounts. Just you, the timer, and a deeper understanding of your own practice. — PRESENCE DETECTION — Sit's accelerometer reads real stillness during every session — completely on-device, zero permissions required, zero data transmitted. After each session, your Presence Score shows exactly how still you remained. Over time, Stats reveals your average presence and longest streaks. — CAMERA QUALITY TRACKING — Enable optional front-camera tracking for the fullest picture. Sit uses Apple's Vision framework entirely on-device to detect whether your eyes are closed, your head is upright, and your face is still. No images or video are ever saved or transmitted — only a single quality number, stored locally on your iPhone. Zero cloud. Zero biometrics. Pure presence. — AI MEDITATION INSIGHTS — History surfaces personal insights about your practice. Powered by Apple Intelligence on iOS 26+, or a thoughtful rules-based insight on older devices — always on-device, always private. Learn which time of day deepens your practice, how your quality is trending, and what your consistency streak says about your discipline. — THE TIMER — • 5, 10, 15, 20, 30, 45, or 60-minute presets — or custom up to 2 hours • Gentle bell that rises naturally at the end • Audio continues in the background when screen locks — AMBIENT SOUNDS — • Rain, singing bowls, forest, ocean, white noise • Plays under any app — layer with your own music — BREATHING GUIDE — • 4-7-8 pattern with smooth circular animation • Settles the mind before the silence begins — HISTORY & STATS — • Full session log with quality score and completion rate • Daily streaks — consistency is the practice • Logs Mindful Minutes to Apple Health automatically — BUILT ON PRIVACY — • No account, no sign-up, no email — ever • Camera: frames processed in memory, discarded immediately, never saved • Motion: processed locally, never leaves device • AI insights: run on-device — no server, no API call • Optional anonymised session stats (count, quality, streak only) to help improve future insights — your explicit consent, revocable anytime from Settings Sit. Still your mind. Watch it grow. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
