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.

CalendarSpeak turns your voice into organized events, tasks, and reminders. No typing, no tapping through date pickers. Say what you need and watch it land on your calendar in seconds. 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. FEATURES ◆ Voice-First Scheduling Record up to 60 seconds of natural speech. The AI parses dates, durations, locations, recurrence rules, and priority levels automatically. ◆ Smart Calendar Views Switch between Day, Week, Month, Year, and Agenda views. See your timeline at a glance or zoom into a single hour. ◆ Recurring Events Made Easy Daily, weekdays, weekends, weekly, biweekly, monthly — set it once by voice. Skip a single occurrence or end the series whenever you want. ◆ Priority-Based Reminders Four levels: Low, Medium, High, Urgent. Each gets its own notification timing so important events break through and minor ones stay quiet. ◆ Two-Way Apple Calendar Sync Events flow both directions. Anything you create here appears in Apple Calendar, and events from iCloud, Google, Exchange, or any account already on your iPhone sync back automatically. (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. Tap to jump straight into CalendarSpeak. ◆ Multi-Language Speak in your language — the assistant detects it automatically and responds accordingly. Interface available in multiple languages.
