Family on iCloud. Holidays from some website. Birthdays buried in your contacts. Work on the phone. Simple Calendar brings them all together β€” plus your to-dos and your day counters β€” in one app on Android.



One app for your whole life, not just your schedule.



πŸ”„ SYNC EVERYTHING

β€’ iCloud: Switched to Android but your family is still on Apple? Sync your iCloud calendars directly. No bridge, no workaround. Log in securely with an app-specific password.

β€’ CalDAV: Nextcloud, Fastmail, Radicale, BaΓ―kal, Zoho, SOGo, mailbox.org, and more. Native two-way sync, no middleware.

β€’ Device Calendars: Your phone's built-in Google, Samsung, and Outlook calendars show up alongside everything else.

β€’ ICS Subscriptions: Follow any calendar feed. Public holidays, school terms, sports seasons.

β€’ Birthdays & Anniversaries: Pulled from your contacts automatically.



πŸ“… PLAN YOUR DAY

β€’ 7 Different Views: Month, full-height month, agenda, day, 3-day, week, and year.

β€’ Intuitive Control: Pinch to zoom the timeline, drag an event to reschedule it.

β€’ Quick Add: Type "Coffee with John tomorrow 3pm" and it's on the calendar. It understands dates, times, recurrence, and locations.

β€’ Smart Insights: See where your time goes: busiest days, back-to-back streaks, free blocks. Computed entirely on-device.



βœ… GET THINGS DONE

β€’ Tasks: A powerful local to-do list with optional due times, priority levels (High/Medium/Low), notes, and colored categories. Works fully offline.

β€’ Day Counters: How many days since you quit smoking? How long until your vacation? Track it with a simple "days since / days until" counter.



πŸ“² 9 STUNNING WIDGETS

Glance at your day without opening the app. 9 different widgets, sized for every way you live:

β€’ Today's Agenda & Upcoming: What's coming up next at a glance.

β€’ Month & Month + Agenda: The big picture, with your events right beside it.

β€’ Day Counters: Keep your biggest milestones and goals always in view right on your home screen.



πŸ”’ PRIVATE BY DEFAULT

β€’ No Account Required: We have no servers, so there is nothing to collect, share, or sell.

β€’ High-End Encryption: Credentials are encrypted with the Android Keystore (AES-256-GCM).

β€’ App Lock: Hide your schedule behind your fingerprint, face, or screen lock.

β€’ Fully Offline: Works perfectly offline out of the box.



🎨 MAKE IT YOURS

β€’ Material You: Dynamic theming that follows your system colors, plus custom light and dark modes.

β€’ Universal Search: Full-text search across every event and task.

β€’ Global: Set the app's language from Android settings β€” 46 languages supported. ## Rankings - #2,967,483 β€” Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_LOCAL_NETWORK` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.FOREGROUND_SERVICE_DATA_SYNC` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.READ_BASIC_PHONE_STATE` - `android.permission.READ_CALENDAR` - `android.permission.READ_CONTACTS` - `android.permission.READ_SYNC_SETTINGS` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.USE_BIOMETRIC` - `android.permission.USE_EXACT_ALARM` - `android.permission.USE_FINGERPRINT` - `android.permission.VIBRATE` - `android.permission.WAKE_LOCK` - `android.permission.WRITE_CALENDAR` - `android.permission.WRITE_CONTACTS` - `android.permission.WRITE_SYNC_SETTINGS` - `com.android.vending.CHECK_LICENSE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` - `nl.simpletools.calendar.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [KashCal: Sync iCloud & CalDAV](https://chrome-stats.com/d/org.onekash.kashcal) β€” 215 users - [OneCal: Unified Calendar](https://chrome-stats.com/d/io.onecal.onecal) β€” 1,786 users - [Calendar 2026- Simple Calendar](https://chrome-stats.com/d/com.native.calendar.schedule.planner) β€” 73,375 users, 4.29 / 5 - [Calendar 2026: Simple Calendar](https://chrome-stats.com/d/com.calenderlatest.yami) β€” 10,966,369 users, 4.65 / 5 - [Simple Calendar Sync](https://chrome-stats.com/d/me.rperez.calendarsync) β€” 551 users - [Calendar](https://chrome-stats.com/d/com.mmb.calendar) β€” 256 users - [Simple Calendar - Plan Easily](https://chrome-stats.com/d/com.appgenix.calendar) β€” 263,860 users, 4.63 / 5 - [My Calendar - Planner & Tasks](https://chrome-stats.com/d/com.iter.schedule) β€” 200 users - [CalendHome](https://chrome-stats.com/d/com.alexpuntoesse.calendhome) β€” 19 users - [True Calendar](https://chrome-stats.com/d/com.trueapp.calendar) β€” 2,576 users - [aCalendar - your calendar](https://chrome-stats.com/d/org.withouthat.acalendar) β€” 11,755,811 users, 4.41 / 5 - [Simple Planner, Smart Calendar](https://chrome-stats.com/d/com.planner.calendar.schedule.todolist) β€” 15,399 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/nl.simpletools.calendar)
