[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.
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.

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.

Straightforward and Simple

I love this calendar app. I like being able to see my month at a glance and I like the widget you can put on your Home Screen. The ads aren’t intrusive and never actually interrupt what you’re doing, I don’t even usually notice them. I like that you can set a location for events happening but don’t have to. My only problems are nitpicks at worst:

*if you have multiple emails it will import holidays from each email so each holiday has it listed multiple times. If there is a way to turn this off I haven’t found it.

*I would love for more darker color pallets, with the white background replaced with more muted colors, but still with fun color accents.

Developer Response ,

Thank you for the wonderful review. You can turn off the display of unwanted holiday calendars from the settings screen. Please give it a try. Regarding the darker color palettes, we are considering adding more theme colors in future updates, so we will include some themes with more muted background colors. Thank you for your request. We hope you continue to enjoy using our app. Thank you very much.

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!!

Developer Response ,

Thank you for the wonderful review! If it were possible, we would love to remove ads and make it the perfect calendar app, but we have to include minimal ads to keep up with new iOS updates. However, we have no plans to introduce a subscription model for our calendar app. If you are interested, please consider a one-time purchase to remove ads. We hope you continue to enjoy using our app. Thank you very much.

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.
