HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (4762 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

★★★★★ I bought the paid version on iPad to remove ads but when I opened it on iPhone with same AppleID it seems like I have to pay full price again.
★★★★★ At first, the calendar was easy to use and worked fine, but suddenly the events I had saved shifted by one day. I had to check all my events and rewrite them in the calendar. Even though I bought the app. Why did this…

Forces to link

For some reason, the app only works if you allow it to give access to your other Calendar apps for you to be able to use it do not like that whatsoever should have an option to not have to link them very frustrating. I wanted to separate different calendars for different things.

★★★★★Aug 30, 2026
Awesome 🙌👍☺️

I love 💕 this candler its very helpful

Very good app just not what I was looking for would recommend

★★★★★May 27, 2026
Up until today

Why all of a sudden I have Asian words and numbers in my simple calendar? I wish I could speak Asian language but I can’t so what’s happening to my Simple Calendar

★★★★★Apr 30, 2026
Completely useless

Nobody is downloading a separate app to immediately sync it with their own calendar. This app is absolutely useless unless you’ve somehow managed to delete you standard calendar. My intent was to use this app for tracking fitness but instead I accidentally deleted every event on my standard calendar so now I will be on the phone with clients for the rest of the day. Really appreciate that!

★★★★★Apr 20, 2026
Deleted all my data

This app randomly deleted all my data when I was running low on phone storage without any notice and customer support will not respond to me.

Store description

Simple Calendar is a calendar app that works directly with your iCloud, Google and Microsoft calendars, with clear monthly, weekly and daily views, color coding, widgets and repeating events. Our design philosophy is all about simplicity and ease of use. Simple Calendar comes with various customization options, including font size — use the style that suits you best. In this calendar app, you can use the sharing features of iCloud Calendar and Google Calendar, making it easy to share schedules with family, partners, and colleagues. It's perfect for those looking for a minimalist calendar app focused on functionality instead of extra (and sometimes unnecessary) features — for work, family, shifts, school and travel. [List of Functions] · Share schedules with iCloud and Google Calendar · 15 Home Screen widgets · Next event on your Lock Screen · Font size adjustment (10 options) · Weekly (7 days · 5 days · 3 days) display · Daily display · Color coding for different calendars · Add notes, URLs, and maps · Sync with other scheduling apps · Event templates, history and search · Add an event to multiple days at once · Daily summary notifications · Restore deleted events from the Trash · 50 theme colors and a changeable app icon · Set your favorite photo as the wallpaper · Background colors for dates · White, black, or colored text for events · Set any day of the week as a day off · Change the start day of the week · Display week numbers · Lock with passcode [Function Details] ■ iOS Calendar This app uses the built-in iOS calendar system. Events made with this app will be synchronized with other scheduling apps and the iOS standard Calendar app. Your events are stored in your own calendar account (iCloud, Google, etc.), never on our servers. If you switch phones, simply sign in again and everything comes back — no account registration needed. Events sync to iPad automatically and can be viewed on a Mac or PC via iCloud.com. ■ Adjust Font Size You can choose from five font sizes of extra-small, small, medium, large, and extra-large. You can also choose light or bold text for better readability. ■ Monthly, Weekly, and Daily Calendar With one tap at the bottom of the screen, you can switch between monthly, weekly, and daily display. Switch the weekly calendar to a 7-, 5- or 3-day display to find what is right for you. A list of the day's events can be shown under the monthly calendar. ■ Color Coding You can create separate calendars according to different schedules, such as work and home. Then, you can manage them clearly by color coding them. For each calendar, you can choose everything from its color to white or black text. ■ Secure Passcode Lock You can securely lock the app with a passcode, Face ID or Touch ID if you don't want anyone to view your calendars. ■ Notification Settings You can set up notifications for scheduled events at the event time, as well as 5 min, 15 min, or more prior to the event, so you don't miss important plans! Get a summary of today's events in the morning or tomorrow's events the night before. Over 21 million downloads, 4.6 user rating (as of August 2026). [Note to Users] Since this calendar app uses the standard function of the iOS calendar, events older than one month may no longer appear on your device with the default settings. If you want to keep past events, please follow the procedure below after installing the app. 1. Open the iOS Settings app. 2. Tap "Calendar". 3. Tap "Sync". 4. Select "All Events". For details, see "Help/FAQ" in the app. [Help / Inquiries] Please visit "Help/FAQ" from the settings screen of the app. If this doesn't help, please contact us through "Contact Us" from the settings screen. We can respond much faster this way than to app reviews. [Terms of Service] https://komorebi-studio.com/tos_en.html [Privacy Policy] https://komorebi-studio.com/policyredirect.html
