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.

[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.

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.
Just got this calendar
RandMart3
This calendar was just downloaded today and I’ve been trying & working toset it up. So far it seems like it has been easy to work with. That might change in a couple of weeks or months after some of the little flaws start toshow. I have already seen a few little things that could be abigger concern later on. First I think the letters need to be able to be able to have the color set ontheir own. They justdon’t matchup with some of the other colors that can beadjusted. Next thelettering needs to be able to be changed from horizontal to vertical so it can fit inthe time slots. Why have them going across when you can only see a couple of letters when they might fit if they were vertical? I could easily come up with more but it’s late and I’m getting tired. But I would like to add that with the App you need to to take sometime and make a listor something else that can be used to answer all of the simple setup or dayto day problems orquestions that people are going to ask you.If they have any moreproblems or they have any technical issues they can stillcontact you either byphone, text or email.

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.
THIS IS IT
Elyarnel
I’ve tried so many calendar apps for my business, and I’ve finally found one that does everything I want. ITS THIS ONE GO AHEAD AND DOWNLOAD IT. I was using a different popular Calendar app for a few years, but they started showing ads on a recent download EVEN WITH A MONTHLY PAYMENT. I’m so glad I found this. You can get rid of the ads with just one (currently $9.99) payment. It’s very easy to read at a glance, something I found the IOS Calendar was lacking. And it has a lot of options to change theme colors, font sizes, and other customizable options. I am so so so very happy I found this app!

It's wonderful to know that the customization options enhance your usage. We're delighted to be a part of your business routine and hope you continue to enjoy using our app!
This update addresses issues and inconveniences introduced by the recent major update.
Improvements
- Restored the previous style of the date and time pickers. We apologize for changing this back so soon after the last update; based on your feedback and a review of usability, we decided to revert it
- Added "Default Event Duration" to Settings > General (choose from 0 minutes to 3 hours; default is 1 hour)
- When you change the start date or time of an existing event, the end time now moves with it so the event keeps its original length
- Long titles are now displayed in full on the event input screen
- Made the dialog shown after saving an event, and the ad inside it, more compact
- You can now reorder templates by long-pressing and dragging them, and edit, duplicate, or delete a template from the long-press menu
- Moved Notification settings to the top level of the Settings screen and grouped the Icon Badge settings under it
- If you previously purchased ad removal, the plan screen now shows your current status correctly
Bug Fixes
- Fixed an issue where a note containing only an email address or URL could no longer be edited
- Fixed an issue where sample events were sometimes not displayed on the widget selection screen
- Fixed other issues that could cause crashes
We're sorry for releasing several updates in a short period. Thank you for all your reviews and reports. As this follows a major update, there may be a few more small fixes in the coming weeks, and we appreciate your continued support.
Your kind reviews mean a lot to us. Thank you for using Simple Calendar.
