The focus timer that keeps the receipts. Most study timers forget you the moment the session ends. but OffShelf files every finished session against a topic, so your hours, streaks and progress stack up into a record you can actually look at. Pick a topic. Press start. That is the whole ritual. — A POMODORO TIMER THAT DOES NOT LOSE TIME — The timer runs on wall-clock time, so backgrounding the app, locking your phone or taking a call cannot pause it or inflate it. It stays live on your Lock Screen, in a Live Activity, and on your Home Screen widget. Close OffShelf completely and it is still counting. Choose your own rhythm — classic 25/5, long deep work blocks, or no structure at all — and pick a timer style you actually want to look at. — YOUR SHELF, YOUR SUBJECTS — Every subject, skill or project lives as a topic on your shelf. Turn on exactly the panes you want for each one: a focus timer, a task list, notes, or a quiet notes-only topic. Swipe between them mid-session without breaking focus. Give a topic a target and a deadline and it becomes a goal you are measurably closing in on. — PROGRESS YOU CAN SEE — This is the part other focus apps skip. OffShelf turns finished sessions into: • Hours logged per topic, and levels that climb as they add up • A daily study streak, with a weekly Streak Freeze so one bad day does not erase a month • An activity heatmap and a daily study chart • Milestones and achievements as you cross them • Coins and Focus XP for time studied and work finished • A leaderboard ranked on real activity — PLAN THE WEEK, NOT JUST THE HOUR — Set recurring schedule blocks for the subjects you keep meaning to get to, and today-only focus goals for the ones you cannot put off. When you genuinely do not know where to start, OffShelf picks a topic for you, based on what you have been neglecting and how close you are to levelling up. No guessing, no blank page. — STUDY WITH A FRIEND — Pair with a study buddy and see when they are actually studying, what they have finished today, and what is still on their plan. Send a nudge when they go quiet. Start a live co-study session and share a clock. Accountability without either of you having to perform. — BEAT PROCRASTINATION BY MAKING IT VISIBLE — Self discipline is easier when the evidence is on your side. Streaks give you something to protect, levels give you something to climb, and the heatmap makes a skipped week impossible to argue with. — WORKS WHEN YOUR SIGNAL DOES NOT — OffShelf starts fast and works offline. A weak connection never stands between you and a focus session. OFFSHELF PREMIUM • Distraction tracking — see what actually pulls you away • Planning and focus insights • Two streak rest days every week • More custom timer styles • The Royal Magic mascot collection • An ad-free app Your topics, sessions, notes and schedules stay private to your account.
