Read full description

Turn upcoming Calendar events and dated Reminders into alarms you can manage from your iPhone. Event Alarm Sync reads the calendars you select, builds a clear timeline of upcoming events and alarm times, and delivers alarms through AlarmKit by default, or through standard notifications when you choose Respect Silent Mode. The app processes Calendar and Reminder content locally. PLAN ALARMS AROUND YOUR SCHEDULE • Use reminder times already attached to Calendar events • Apply a default minutes-before offset • Create custom reminder offsets for individual events • Include incomplete Reminders that have due dates • Choose App Reminder Only timing without changing Calendar alerts STAY IN CONTROL • Choose which calendars can create alarms • Filter all-day, tentative, and declined events • Silence or restore individual alarms • Confirm deletion of eligible writable Calendar events or Reminders • Separately replace eligible Calendar alerts after verified app delivery, with a conditional restore option • Turn all event alarms off with one master control • Choose a fixed snooze time or open a meeting link when available CHOOSE HOW ALARMS ARRIVE • Always Sound uses the iOS alarm screen and system Stop control • Respect Silent Mode uses standard notifications that Silent Mode, Focus, Scheduled Summary, or notification settings may mute or delay • Tap a notification to open Stop, Snooze, or Join in the app; standard notifications do not show a full-screen alarm • Respect Silent Mode requires Notifications, Alerts, and Sounds access and room for no more than 48 pending notifications for this app. If a later schedule exceeds the budget, the app can return to Always Sound and show the change in Settings. PERSONALIZE EACH ALERT • Select from the system alarm sound or five included sounds • Choose how much event information appears in the alarm title • Preview included sounds before scheduling CHECK WHAT IS NEXT • Review upcoming Events and Alarms in the app • Add Home Screen widgets in small, medium, or large sizes. The Event Alarms master control supports both delivery modes; individual alarm controls in Respect Silent Mode open the app. • Add an accessory widget to the Lock Screen • Keep alarm state synchronized between the app and its widgets PRIVACY BY DESIGN Core calendar, reminder, alarm, settings, widget, and diagnostic data is processed locally. When Share Anonymous Analytics is enabled, Event Alarm Sync sends a small allowlisted set of anonymous usage and sanitized reliability data. Turn it off at any time in Settings. Calendar or reminder content, meeting links, alarm times, and local diagnostic logs are never sent. The app has no account system, advertising, or cross-app tracking. Requires iOS 26 or later. Sound, vibration, notification presentation, and background calendar refresh timing depend on iOS settings and system behavior. Manual delivery-mode changes are blocked when an alarm or Snooze is due within 15 minutes. Settings reports when delivery cannot be verified.

Write your to-dos on just two pages: Today and Tomorrow. By keeping the features simple, we could focus on how it feels to open every day. Well-used paper, pages that bend as they turn, a cover that opens when you slip off the elastic strap, the sound of a pen crossing things out — DayTodo is a to-do app that feels like a real notebook. - Today and Tomorrow only • Today's tasks go on the left page, tomorrow's on the right. • Didn't finish something? Send it to tomorrow with a single tap. • When the date changes, tomorrow's tasks move to today automatically. • Finished tasks get a hand-drawn strike-through and are tidied away the next day. - Animation • When you switch lists, the paper bends as the page turns. To jump far ahead, a whole stack of pages turns at once. • When you open the app, the elastic strap slips off and the cover opens. • Crossing out, sending to tomorrow, peeling and placing sticky notes, adding a bookmark — each motion is tuned by hand. • You can turn animations off in Settings. - The sounds of paper • Pages turning, the cover opening, the elastic strap, a pen crossing out, sticky notes and the bookmark ribbon. • All kept soft. You can turn them off in Settings. - Choose the look • Font: Handwriting / Pencil / Quirky / Scribble / System • Paper: New / Worn / Vintage (unlocked as you keep using it) — down to yellowing, coffee rings, and a scuffed cover. Marks sit in different places on each page and stay put from day to day. • Rules: Lined / Grid / Plain (line spacing follows your text size) • Background: Black / Walnut / Birch / Maple / Old Desk / Gray • Text size: Small / Medium / Large / Extra Large / Automatic - Sticky notes • Give each list a sticky note in one of 10 colors. • Press and hold to move it anywhere along the top. Tap the top edge of the page to stick one right there. • Other lists' notes peek over the top of the page — tap one to turn to that list. - Bookmark • Slip a bookmark into the list you use most. Its ribbon lies between the Today and Tomorrow pages. • On other pages, a little of the ribbon peeks out — tap it to jump straight back. • The app opens to your bookmarked list. - Private and secure • Lock your notebook with Face ID or Touch ID. • No ads. No analytics. No tracking. • What you write stays on your device. • Manual backup to a file and restore are free. - Premium (one-time purchase) Buy once, keep it forever. • Unlimited tasks (free: up to 10 in total) • Up to 10 lists (free: up to 2) • Automatic iCloud backup • Worn and Vintage paper and covers right away (free: unlocked after you open the app on 7 and 30 days) Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://daily-apps-showcase.pages.dev/privacy/daytodo/
