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.

HOW IT WORKS Tap the mic, speak naturally, done. The AI assistant understands context, dates, times, and recurring patterns — even when you ramble. Say things like: • "Team standup every weekday at 9 am" • "Move tomorrow's dentist to Friday at 3" • "Cancel next Monday's gym session" • "Add a birthday dinner Saturday at 7 pm, high priority" CalendarSpeak proposes the change, you confirm with one tap — or turn on auto-accept and let it flow hands-free.

(Pro) ◆ Color Tags & Organization Eight color options to visually group work, personal, health, and social events at a glance. ◆ Siri & Shortcuts Support Trigger recordings or send text commands from Siri, the Shortcuts app, or your Home Screen widget without opening the app. ◆ Widget See upcoming events right on your Home Screen.
