OffShelf is a study timer and study tracker for anyone whose phone keeps winning. Start a focus session, block the apps that pull you away, and watch your study hours add up, alone or with friends. Pick a topic. Press start. That is the whole ritual. — A FOCUS TIMER THAT KEEPS COUNTING — • Pomodoro (25/5), long deep-work blocks, or open-ended sessions • Face-down mode: the timer only runs while your phone lies face down. Pick it up and it pauses. • Runs on wall-clock time, so locking your phone or taking a call can't pause it or inflate it • Live on your Lock Screen, in a Live Activity and on your Home Screen widget • Timer styles you'll want to look at: a candle under the night sky, a train, a gravity timer that tilts with your phone, an hourglass and more • Study to rain, white noise, a fireplace or the forest — BLOCK DISTRACTING APPS (PREMIUM) — Pick the apps that steal your time, like TikTok, Instagram, Snapchat or Netflix, and OffShelf blocks them with Screen Time for as long as your session runs. — A STUDY TRACKER THAT KEEPS THE RECEIPTS — Every finished session is filed under a topic, so your progress stacks up into a record you can actually look at: • Study hours per topic, with levels that climb as they add up • A daily streak, with a weekly Streak Freeze so one bad day doesn't erase a month • An activity heatmap and a daily study chart • Milestones, achievements, coins and Focus XP • Tap "Distracted" to log what pulled you away — STUDY WITH FRIENDS — • Pair with a study buddy: see when they're studying and what they finished today, and nudge them when they go quiet • Start a live co-study session and share one clock • Take on your friends in weekly focus competitions • Climb Today's Focus League, a daily leaderboard of real focus minutes — PLAN YOUR WEEK — • One weekly planner for every topic: tap to add a study block, drag to move or resize, repeat it weekly or keep it to one day • Daily focus goals for the things that can't wait • Don't know where to start? "Pick for me" chooses your next topic based on what you've been neglecting — A STUDY FRIEND THAT CHEERS YOU ON — Your study mascot keeps you company while you focus and talks to you about your day. — WORKS OFFLINE — OffShelf starts fast and works without a connection. A weak signal never stands between you and a focus session. OFFSHELF PREMIUM • Block distracting apps during focus sessions • Distraction patterns: see what actually pulls you away • Planning and focus insights • A monthly report with PDF export • Two streak rest days every week • More timer styles • The Royal Magic mascot collection • No ads Your topics, sessions, notes and schedules stay private to your account.
