About

Stillness Timer

Features
Read full description

Stillness is a quiet meditation timer for unguided practice. It gives you structure without noise: no ads, no tracking, no subscriptions, and no account required. Build the session you actually practice. Create simple or multi-phase meditation sessions with custom intervals, chimes, sounds, and haptics. Give each interval its own chime โ€” a soft bell to change posture, a gong to close the practice โ€” or keep one sound throughout. Use Stillness for mindfulness meditation, autogenic training, breathwork, body scans, silent contemplation, or any practice that benefits from timed silence. Practice with your screen locked. Start a session, lock your phone, and set it down. The timer keeps running and your interval chimes sound on time, with minimal battery use. If a phone call arrives, your session pauses and resumes on its own, and the call time is not counted toward your practice. Prefer to watch the timer? Keep the screen awake instead โ€” the choice is yours. Return to presence during the day. Scheduled reminders help you keep a daily rhythm. Spontaneous reminders arrive at unexpected moments during your active hours, gently interrupting autopilot and inviting you back to awareness. You can also keep spontaneous reminders away from scheduled sessions with a 10, 20, or 30 minute buffer. Keep your rhythm across time zones. Stillness supports reminders tied to local time or to a specific time zone. This is useful when traveling, following a fixed practice schedule, or keeping a home-time routine while away. Track progress privately. See your completed sessions, streaks, milestones, total minutes, and favorite practices. Your data stays on your device. Optional Apple Health integration can write completed sessions as Mindful Minutes when you choose to enable it. Move to a new device privately. Device Migration lets you back up sessions, statistics, reminders, and settings to your private iCloud container, restore them on a new device, and clear the transfer data when you are done. No accounts. No external servers. Stillness is for people who want meditation to stay simple: a timer, gentle cues, useful reminders, private progress, and space to practice.
