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 is the ADHD-friendly calendar you just talk to. Say it the way it comes out — messy, half-finished, all at once — and it becomes events and reminders on your calendar. No typing, no date pickers, no forms. WHY IT WORKS FOR BUSY, SCATTERED DAYS • One tap, then talk. Capture a plan before it slips your mind. • Say it messy, we'll sort it. Dates, times, places, repeats and priority are picked out for you. • You stay in control. Every change is shown first — accept, edit or skip with one tap. Or turn on auto-accept and go hands-free. • Reminders that break through. Urgent events arrive as Time Sensitive notifications, so they can reach you even in a Focus mode. JUST SAY THINGS LIKE • "Dentist Friday at 3, remind me an hour before" • "Team standup every weekday at 9 am" • "Move tomorrow's dentist to Friday at 3" • "Cancel next Monday's gym session" • "Birthday dinner Saturday at 7 pm, high priority" FEATURES ◆ Voice-first scheduling — up to 60 seconds of natural speech. Dates, durations, locations, repeats and priority are filled in automatically. ◆ Create, move or cancel by voice — not just new events. ◆ Recurring events made easy — daily, weekdays, weekends, weekly, every two weeks or monthly. Skip one occurrence or end the series anytime. ◆ Priority-based reminders — Low, Medium, High and Urgent, each with its own timing, and more than one reminder per event. ◆ Two-way Apple Calendar sync (Pro) — events you create here appear in Apple Calendar, and events from iCloud, Google, Exchange or any account on your iPhone flow back automatically. ◆ Day, Week, Month, Year and Agenda views. ◆ Color tags — eight colors to tell work, personal, health and social plans apart at a glance. ◆ Siri, Shortcuts and a Home Screen widget — add events without opening the app. ◆ Your language — speak in your own language; the assistant detects it automatically. The app is available in 10 languages. ◆ Made for iPhone, iPad and iPhone Duo. FREE AND PRO CalendarSpeak is free to use with a daily voice input allowance, plus full access to calendar views, reminders, widgets and Siri shortcuts. If the assistant can't find a match, or you skip every suggested change, that input doesn't count. CalendarSpeak Pro unlocks unlimited voice inputs and two-way Apple Calendar sync. Choose monthly, yearly with a 3-day free trial, or a one-time lifetime purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Payment is charged to your Apple ID at confirmation. Manage or cancel anytime in your App Store account settings. CalendarSpeak is a planning tool, not a medical device or treatment.
