Lock vs Focus Timer

Lock-in is a social study app built around Pomodoro sessions. Start a focus session, grind together with others, share your progress, and stay accountable. Turn screen time into real productivity.

Focus for 25 minutes — and a building rises in your city. Focus Timer is a calm Pomodoro timer with a reason to stay off your phone: every session you finish becomes one building in a little isometric city that's yours to explore. Quick sessions raise cottages; long deep-work sessions raise townhouses and apartment blocks. Keep showing up and your city grows whole districts — leafy neighborhoods, a market square, parks, and one day, a clock tower. • One finished session = one building, forever — tap any building to see the day, the minutes, and what you were working on • Longer sessions build bigger buildings • A real little city: roads, gardens, districts, landmarks — pinch, pan, explore • Classic Pomodoro breaks, gentle and optional • Pick your length: presets, or a simple stepper up to an hour • Streaks and lifetime focus stats • No account, no ads getting in the way of the work — everything stays on your device Free for 7 days, then a single one-time unlock. No subscription, ever. Part of Appopolis — a little city of small, focused apps.
