Simple Calendar Daily Planner

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.

[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.
