On-Timer helps people with ADHD be on time for meetings with a 3-stage alarm sequence that coaches you through preparation. HOW IT WORKS On-Timer reads your calendar and lets you set three coaching alarms for any meeting: โ€ข Get Ready (30 min before) โ€” "Time to wrap up!" โ€ข Get Set (15 min before) โ€” "Head to your desk!" โ€ข Go! (1 min before) โ€” "Join now โ€” you've got this!" All timings are configurable in Settings. TWO REMINDER LEVELS โ€ข Alert (blue bell) โ€” Standard time-sensitive notification โ€ข Alarm (red bell, iOS 26+) โ€” Prominent AlarmKit alarm that breaks through Focus and silent mode, so you'll always hear it VISUAL COUNTDOWN A full-screen countdown view with a kitchen-timer dial and chevron stage indicator shows exactly how long until your meeting. The chevron motif (orange โ†’ yellow โ†’ green) tracks your progress across the app, widgets, Dynamic Island, and Live Activity. Tap any meeting to view full event details โ€” attendees, notes, location โ€” without leaving the app. APPLE WATCH A full Apple Watch app with meeting list, countdown view, alarm toggle, and "I'm Ready" rewards. Paired iPhone and Watch sync over Bluetooth for near-instant updates, so an alarm set on one appears on the other right away. Four complication styles โ€” corner, circular, rectangular, and inline โ€” keep your next alarm visible on any watch face. ICLOUD SYNC Blue-bell Alerts sync between your iPhones and iPads via iCloud, so the alarms you set on one device follow you to the others. LIVE ACTIVITY & DYNAMIC ISLAND A persistent countdown on your Lock Screen and Dynamic Island from the first alarm stage until the meeting starts. HOME & LOCK SCREEN WIDGETS Small and medium Home Screen widgets, plus circular, rectangular, and inline Lock Screen widgets โ€” all with chevron progress indicators. AI MEETING PREP On-device Apple Intelligence suggestions help you prepare for each meeting based on its title, timing, attendees, and notes. Requires an Apple Intelligence-capable device on iOS 26+. "I'M READY" REWARDS Tap the button during Get Ready or Get Set to celebrate with confetti and unlock a personal micro-reward from your custom list. ALSO โ€ข Volume-off detection warns you if your phone is silenced and offers to upgrade to the red Alarm tier โ€ข Past alarmed meetings shown for quick reference โ€ข Pull-to-refresh, and automatic refresh when your calendar changes REQUIREMENTS โ€ข iOS 17.6+ (core features) โ€ข watchOS 10+ (Apple Watch) โ€ข iOS 26+ on an Apple Intelligence-capable device (red Alarm tier and AI prep) โ€ข iCloud account for cross-device sync โ€ข Calendar and notification permissions

Your calendar already knows where you need to be. Your phone should fight to get you there on time. Calendar notifications fail silently. Silent Mode swallows them. Focus Mode buries them. And when you finally look up from your work, the meeting started five minutes ago โ€” camera off, no context, scrambling for the link. Call to Meet exists because your meetings deserve more than a notification. HOW IT WORKS Call to Meet reads your calendar and sets real system alarms โ€” not notifications โ€” that ring through Silent Mode and Do Not Disturb. Like your morning alarm clock, but for meetings. A persistent countdown appears on your Lock Screen and in Dynamic Island, so you always know exactly how much time you have. When it's time, join Zoom, Google Meet, Microsoft Teams, Webex, or a phone call with a single tap. Bad connection? No laptop nearby? If your invite includes a dial-in number โ€” common in Zoom, Google Meet, and Teams invites โ€” Call to Meet shows a call button. One tap dials the number and, if your invite includes a PIN, enters it for you. Works without WiFi. Useful when you're driving or when your connection is unreliable. On the go with just your Apple Watch? Join from your wrist over cellular โ€” no iPhone required. Real alarms, not notifications. That's the difference. Real alarms require the Alarms permission. Without it, Call to Meet falls back to standard notifications. FLIGHT TRACKING Traveling to your next meeting? Call to Meet tracks your flight in real time โ€” gate, terminal, departure status, and route progress โ€” right on your Lock Screen and Dynamic Island. Know the moment your gate changes. See inbound aircraft status so you know if your flight will be late before the airline tells you. One persistent live view from check-in through landing. CAPTURE EVENTS FROM ANYWHERE Point your camera at any meeting invite โ€” email printout, whiteboard, screen โ€” and Call to Meet extracts the details instantly using on-device AI. No typing. No copy-pasting. The event lands in your calendar ready to alarm. KEY FEATURES - Dynamic Island โ€” Countdown visible at a glance without unlocking your phone. A persistent timer on your Lock Screen shows exactly when your next meeting starts. Always visible. Hard to miss. - System Alarms That Cut Through โ€” Real system alarms via AlarmKit. Silent Mode won't stop them. Do Not Disturb won't stop them. They ring because they're alarms, not notifications. - Flight Live Activity โ€” Real-time gate, terminal, and route progress on your Lock Screen for every flight. Inbound aircraft tracking so you know delays before they're announced. - One-Tap Join โ€” Jump into Zoom, Google Meet, Teams, Webex, or any platform with a single tap. Join by app or by phone call โ€” your choice. If the invite includes a dial-in number and PIN, Call to Meet dials it and enters the PIN for you. No WiFi required. - Apple Watch โ€” Join meetings directly from your wrist with cellular. See your next meeting countdown with complications that keep you on time โ€” even without your iPhone. - Camera Event Capture โ€” Point at any meeting invite and Call to Meet reads it with on-device AI. No typing required. - Focus Mode Filter โ€” Choose which calendars show up in each Focus Mode with an iOS Focus Filter. Only see what matters right now. ALSO INCLUDED โ€” EVERYTHING IS FREE - Unlimited simultaneous alarms - Auto-alarm for meetings or all events - End-of-meeting alarms โ€” know when to wrap up - Track multiple flights simultaneously - Alarms for any event type Works with your existing calendar. No account required. Available in English, Spanish, German, French, Italian, Japanese, and Simplified Chinese.
