■ iOS Calendar
This app uses the iOS calendar app. Schedules made with this app will be synchronized with other scheduling apps and the iOS standard calendar.
■ Adjust Font Size
You can choose from five font sizes of extra-small, small, medium, large, and extra-large.
You can also pick between light and bold font, to make prioritized events pop up better.
■ Monthly, Weekly, and Daily Calendar
With one tap at the bottom of the screen, you can switch between monthly, weekly, and daily display.
Switching the weekly calendar between 7, 5 or 3 day display allows you to find the display that is right for you.
The app memorizes the calendar style used the last time you opened it, making it super convenient for people who only want to use the weekly display.
■ 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. You can switch the background color between white and black as well.
■ Secure Passcode Lock
You can securely lock the app with a password if you don't want anyone to view your calendars. Of course, you can also lock with Face ID and Touch ID as well.
■ 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!
[Note to Users]
Since this calendar app uses the standard function of the iOS calendar, all schedules older than one month may disappear with the default settings. This also applies to other apps. 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".
This should solve the problem.
If you still have questions, visit the "Help/FAQ" page in the app for further details.
【Help/Inquiries】
Please visit "Help/FAQ" from the settings screen of the app. If this doesn't help, please contact us through "Inquiry / Feedback" from the settings screen. We can respond to you much quicker this way, so please do so instead of asking us questions in the app review, since it takes a while for those to be reflected onto the page.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
