Quiet Interval
Read full descriptionHide full description
Quiet Interval is a calm interval timer that stays out of the way. Pick a length, choose an optional reminder, and press Start. Quiet Interval cues you with a soft bell tone or a tap every interval, then a deeper chime when your session ends. No alarms, no clutter, one screen. USE IT FOR • Meditation and breathwork • Focused work sessions • Stretching, yoga and planks • Power naps and rest breaks WHY IT FEELS DIFFERENT • On time with the screen locked. Cues are scheduled to the sample, so they land exactly when they should, even with your phone in your pocket and the ring switch on silent. • Plays nicely with your music. Tones mix in over podcasts and playlists instead of stopping them. • A moment to settle. Start after 5, 10, 15 or 30 seconds so you can get comfortable first. • Sound, haptic or both. • Sessions from 1 minute to 2 hours, with reminders from every 30 seconds to every 20 minutes. APPLE WATCH A standalone Watch app taps your wrist for every reminder, even with your arm down, for sessions up to an hour. IPAD AND MAC The same calm timer on your desk, for work sprints and breaks. PRIVATE BY DESIGN No account, no ads, no analytics, no tracking. Nothing ever leaves your device.
