Read full description

QuietSession is a discreet haptic time-boundary tool for sessions, meetings, talks, coaching calls, consultations, and focused work. It helps you keep track of time without sound, alarms, or visible interruption. Create or choose a preset on iPhone, start a session from iPhone or your paired watch, and receive quiet haptic cues on your wrist as the session approaches its end. If a conversation runs long, a gentle overtime signal repeats until you confirm — and the extra minutes are tracked in your history. QuietSession is useful for: • therapists, coaches, and counselors running client sessions • consultations and 1-on-1 meetings • interviews, presentations, and talks • focused work blocks • any situation where checking a timer would feel distracting Core features: • built-in session presets • discreet wrist haptic cues • 5 min reminder, 1 min reminder, and end signal • pause and resume a running session • optional overtime signal with overtime tracked in History • start sessions from iPhone or your paired watch • optional notifications • quiet running screen with Invisible Mode • local session history • available in English, Spanish, German, French, Portuguese, Japanese, Chinese, and Russian • no account, no ads, no tracking QuietSession Pro unlocks custom presets, custom durations, profession preset templates (starting with Therapist), adjustable haptic signal setup, signal intensity controls, full history calendar, and CSV export for billing and timekeeping. QuietSession is not a generic timer. It is designed for moments where time boundaries matter, but interruptions do not.
