About

Focus/Rest

Features
Read full description

Focus/Rest is a premium Pomodoro timer designed to help you stay productive with a stunning, physics-driven interface. SET YOUR RHYTHM Spin the control wheel to dial in your focus and rest durations. The responsive wheel features real inertia โ€” flick it and watch it coast to your perfect time. Switch between Focus and Rest modes with a single tap on the glass lens. STAY IN THE ZONE Once your timer starts, a breathing glass lens pulses gently as time counts down. When the period ends, the next one begins automatically โ€” Focus and Rest cycle endlessly until you decide to stop. No interruptions, no tapping "next." DYNAMIC ISLAND & LIVE ACTIVITY Your timer lives in the Dynamic Island and Lock Screen. The countdown continues seamlessly even when you leave the app, automatically cycling through Focus and Rest periods. Tap controls right from the Dynamic Island โ€” play, pause, stop, or switch modes without opening the app. FEEL THE TRANSITION Custom haptic patterns mark each transition: an energising pulse when Focus begins, a calming wave when Rest starts. Your body learns the rhythm before your eyes even see the screen. CRAFTED DETAILS โ€ข Glass morphism lens with real-time parallax driven by device motion โ€ข Breathing glow animation that follows your timer โ€ข Rotatable control wheel with physics-based inertia โ€ข Color-coded modes: purple for Focus, green for Rest โ€ข Multiple alert sounds with per-mode customization โ€ข Works in portrait and landscape MINIMAL & FOCUSED No accounts. No subscriptions. No ads. No tracking. Just a timer that respects your time as much as you do.
