TopCalendar
Read full descriptionHide full description
TopCalendar is a modern calendar for iPhone and iPad. It offers gesture-based navigation and a range of view layouts in a clean, native design with full dark mode support. Swipe, don't search Two clearly separated swipe axes make navigation intuitive: swipe horizontally to change the time period (year, month, week, day, agenda), swipe vertically to move through time. The day under your finger travels with you across view changes, so you always land exactly where you meant to. All views β’ Year: a multi-year overview with event density per day, showing multi-day events across their full length instead of only on the first day β’ Month: a grid with week numbers, events and a subtle moon phase indicator β’ Week: day tiles in a 2x4 grid with the week number β’ Day: an event list with times, birthdays and moon phase β’ Agenda: a chronological, scrollable list Reliable reminders Reminders arrive through your device as dependably as any system calendar alert, plus a TopCalendar notification of its own that takes you straight back to the event in the app. Short-notice reminders are classified as time-sensitive, so they break through Focus. Your data, your choice TopCalendar has no server of its own and no cloud. Your events stay in Apple's calendar store (EventKit), right where you already sync them via iCloud, Google or Exchange. There is no extra account, no sign-in, and nothing to lose if you are offline. What the app counts for you (events created, changed, deleted) only you see, on the statistics page. Widgets and more β’ Two home screen widgets: a month overview with event density, and a day view with your hours β’ A lock screen widget for your next event β’ Birthdays from your contacts (optional) or from the birthday calendar β’ Holidays from subscribed calendars, week numbers in the grid History A page of its own shows what you changed in TopCalendar, with calendar and account, and restores any of it. The undo toast is gone in seconds; that an event is missing you notice hours later. Automation Works with Siri and the Shortcuts app: say or type an event as free text. If it is recognised unambiguously, TopCalendar creates it directly, otherwise the app opens for confirmation. TopCalendar: power-user handling, thought through, in a modern design. TopCalendar Pro Statistics, copying events to several days, the older undo history, more than three birthdays and the Lock Screen, StandBy and Day Arc widgets are part of TopCalendar Pro.

Verdict
The clearest difference is in-app purchases: Oursync at none against TopCalendar's 2. Oursync also leads on iOS requirement (15.0 vs 17.0). TopCalendar's advantage is update cadence (every 4 days vs every 3 weeks). On price, ads and device support there is nothing between them.
