Unheld
Read full descriptionHide full description
Unheld is a quiet space for focus. Most focus apps make you watch the clock. Unheld does the opposite. Start a session, put your phone down, and focus without thinking about time. There are no ticking countdowns, no pressure, and no productivity scores. Time is held quietly in the background so you can stay present with your work. Unheld is designed for people who want calm focus instead of urgency — students, creatives, professionals, and anyone who finds traditional timers stressful. Features • One-tap focus sessions • No countdown by default • Gentle end reminders (optional) • Session history for reflection, not tracking • Apple Watch support • Local-only storage — your data stays on your device Premium (One-time purchase) Unlock session history, weekly summaries, and optional tags with a single purchase. No subscriptions. Designed for calm Unheld is not a Pomodoro timer and not a productivity system. It’s a quiet container for focus — so you can stop thinking about time and simply work.
