[Function Details]

■ 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.
Because the app memorizes the calendar style used the last time you opened it, it's 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. And then, manage them clearly by color coding them. You can switch the background color between white and black as well.

■ Secure passcode lock
You can lock the app with a password securely, if you don't want people to see your calendars. Of course, it corresponds to Face ID, Touch ID as well.

■ Notification settings
You can set up notifications for scheduled events, at the event time and also 5 min, 15min, 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 setting. This also applies to other apps. If you want to keep past events, please follow the procedures 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 from the app for further details.

Please visit "Help · FAQ" from the setting screen of the app. If this doesn't help, please contact us through "Inquiry / feedback" from the setting 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.

I am a full time college student who also has a million doctors appts, a wonky work schedule, and a family of 12 to schedule around. This app is the BEST. There are a million different colors to use for an unlimited amount of calendars so that you can stay organized. You can also make templates that I use mostly for college classes and work schedules. You can also set up the widget so that you can see everything on your Home Screen. And ITS FREE. The only downside is that there is a tiny ad at the bottom of the screen but it is so out of the way and not obnoxious that I forget it’s there all the time. If I could give this a million stars I would!!

Thank you! Finally an app that copies AND offers templates!

Thank you for creating a calendar that allows you to copy events, as opposed to only allow repeating events. I do a lot of the same things, but not necessarily on a strictly repeating cycle. This is making my life SO much easier! I don’t have to start from scratch! I also love how easy it is to see the multiple events on the calendar. There are a ton of colors to customize my multiple calendars & see which is which at a glance. All I need now is a way to add a weather calendar & this will be perfect!

The best I’ve ever used

Update: After using this app for a while I have come to realize that it absolutely the best calendar app for my needs. The app’s simplicity is totally attractive and the clarity and legibility if the presentation is among the best I’ve seen. Add to this a search function the that finds any and all entries into the past, present and future and you are set. Highly recommended.

Previous review: If this app provided the capability for active URL links in the notes section of events it would be a five star app. As it is URL links are inactive and of no use.
