Most focus timers hand you a number at the end of the week. This one hands you a city. Set the timer and put the phone down. Every finished session lays another floor on your tower. Put a roof on it and the whole tower moves into a city you build — where it stands for good and pays you rent every day. BUILT ON THE POMODORO TECHNIQUE Work in one focused block, rest, repeat. Twenty-five minutes on, a short break, a longer one after four — the rhythm people have used since the 1980s, except here each block leaves a floor behind. BUILT FOR ATTENTION THAT WANDERS Starting is the hard part, so the app makes starting small: one block, 25 minutes, a reward you can see at the end of it. The shield takes the temptation off the table instead of asking you to out-argue it, and a session survives a locked screen — so a wobble costs you nothing. If you have ADHD, that is usually the combination that finally sticks. Focus comes from the rhythm, not from willpower. BLOCK WHAT PULLS YOU AWAY — FREE, ALWAYS • Shut selected apps for the length of a session, using Apple's own Screen Time • Keeps working with the screen locked and outside the app • No limit on how many, no paywall on blocking — ever THE TIMER • Pomodoro presets (10 / 25 / 45 min) or any length you like • Automatic cycles: focus → break → focus, a long break after four • Name the session — every floor remembers what you built it for • Lock your screen and the session keeps running. Nothing is lost. • Your floor rises on the Lock Screen and in the Dynamic Island WHAT YOU KEEP • 6 towers to unlock, each with its own world and music • 6 lands to settle, 12 plots to a city • Finished towers pay daily rent in coins • 32 achievements, from your first floor to a city on every land • Daily streaks with streak protection • Towers, cities and history sync through your own iCloud PROOF YOU DID THE WORK • Export every session as a CSV spreadsheet — date, task, minutes, coins • Or as a printable PDF table, with your totals across the top • Export your city as a picture and show someone what a month of focus looks like • Your tower and streak on a home screen widget, your session on the Lock Screen Useful for a thesis log, for billable hours, or simply for proving to yourself that the week happened. FAIR AND PRIVATE • Free. One-time purchases only — no subscription • No ads. No accounts. No trackers. • We collect nothing. Your sessions stay on your device and in your iCloud. Put the phone down. Build something.
