It’s ideal for anyone who feels guilty about wasted time, wants to secure focus for study, work, or side projects, or simply start a digital detox. ◆ Safe & Private ZenLock runs entirely on-device using iOS system features. No personal data is sent outside.

Pause before you scroll — now with AI Pause. STOP helps you interrupt automatic phone habits before opening distracting apps, so you can make a more intentional next step. AI Pause is a short, structured AI-guided reflection. Instead of jumping straight into a distracting app, STOP helps you slow down, understand what may be driving the urge, and choose a clearer next step. It is not a generic chatbot. AI Pause is designed for one specific moment: right before you open a distracting app. Why STOP • AI Pause before distracting apps When you are about to open a distracting app, AI helps you pause, observe, and decide before slipping into autopilot. • Smarter next-step choices Choose a bounded unlock, not opening the app, or a better-fit alternative action based on your current state. • Classic breathing is still available Prefer a lighter reset? The original breathing-based pause is still here whenever you want it. • 21-Day AI Insights AI analyzes your last 21 days of urges and choices, identifies repeated patterns, highlights what actually works for you, and suggests better next steps. Free & Pro Free Core pause experience with essential features. Pro Unlock AI Pause, stronger interventions, and smarter 21-day AI insights. Privacy Privacy matters. Some features are processed fully on device. AI Pause requires network access and may send the minimum session context needed to generate your guided reflection.
