About

GlanceCal

Features
Read full description

A viewer that lets you see your calendar and reminder information at a glance when you want to know "what's next." It consolidates your schedule and to-do items into a chronological view, allowing you to check plans for today, this week, this month, and beyond. Unlike standard calendar layouts, it is specifically designed to give you an overview of what lies ahead. It is useful for managing work projects and deadlines, organizing family schedules, and tracking events ranging from the short term to the long term. Additional features include a countdown to events (with adjustments for working days) and the integration of multiple calendars and reminders. It works not only on iPhone but also on the larger screens of iPad and Mac (Apple Silicon models). As it relies on color-coding for its display, it does not support Dark Mode.

About

Event Alarm Sync

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.
