ZenLocks helps you put your phone down and return to the life in front of you. Not every quiet moment needs another scroll. Morning coffee with your partner, an afternoon with your child, a patient conversation with your parents, or a few minutes alone with your own breath. ZenLocks turns focus into a clear commitment: choose a duration, start a session, and let system-level blocking keep distracting apps out of reach. Why ZenLocks - Strict focus timer: set a session and stay with it. - System-level app blocking: built on Apple Screen Time APIs to block selected distractions. - Deliberate exit friction: no simple cancel button during a session, so your first decision has a little more weight. - Focus stats: see your sessions, streaks, and reclaimed time. - Privacy first: your focus data stays on device and can sync through your private iCloud account. - No ads, no third-party analytics, no tracking. ZenLocks is not here to punish you for using your phone. It is here for the moments worth protecting: love, family, rest, deep work, and the quiet attention you keep meaning to give back to yourself. Lock screen, unlock life.
