FocusDown helps you put your phone down — literally. Start a focus session, place your iPhone face down on a flat surface, and stay away from distractions until the timer ends. Unlike a normal focus timer, FocusDown turns the simple act of flipping your phone over into a clear commitment. During a session, it helps detect movement, tilting, or picking up the phone and gives you a timely reminder so you can return to focus. Great for: * Studying * Deep work * Reading * Exam prep * Writing * Meetings * Phone-free breaks Main features: * Face-down focus timer * Custom session duration * Movement and tilt reminders * Focus history * Daily and weekly statistics * Achievement badges * Calm dark interface How it works: 1. Choose a focus duration. 2. Tap Start. 3. Place your iPhone face down on a flat surface. 4. Stay focused until the session ends. FocusDown does not block other apps. It helps you build a stronger focus habit by making your phone physically harder to pick up. Put your phone down. Stay with one thing. Build better focus, one session at a time. 1.
