(Updated) Use It Multiple Times a Day

Really like it. I love the Regular-Calendar look of it! It’s working very well & I don’t even have to use the stock iPhone calendar anymore. Its customizable too. Have only 1 minor bug - occasionally & randomly (currently on March 2) the word “Holi” will appear as if a mistake about a US Holiday was not completely deleted by developer. Users cannot delete it. No worries. Great free app.

Update: Taking away a star. Annoyed that past events Disappear after a few weeks. So, looking in app FAQ settings it says to Sync All Events. This IS NOT POSSIBLE in the settings. Not at all anywhere. I need to be able to reference past events. Please Fix This.

Best I’ve Tried .. & I’ve Tried many

This app is the perfect combination for my needs
It has a screen long monthly view that displays all your events and the best part about it for me is that it also displays all my tasks. As someone who relies heavily on their calendar for appointments and to-do lists this is a major point in my book I love that I can check off the tasks as I complete them right on the calendar without having to jump to a different screen or page. For those who can’t see the previous appointments on their calendars after the last couple of weeks, this is an apple setting not a calendar z app issue. To fix this just go to settings-calendars- sync and select ALL EVENTS. This will bring back all appointments from previous months.
I paid the .99 for the ads free version and i think it was worth it.

this is THE BEST calendar app

I have tried all the calendar apps and this is THE BEST by far. I’m an attorney and I have to be in different courtrooms in different courthouses in different cities with different clients, this app helps me manage it all. It has THE BEST monthly view. The monthly view allows you to see text entries in each day, all from within the monthly view. In a quick glance you can see your entire month’s schedule.

My only hope is that I never have to live without this app. Editors, please consider more background colors—from your current selection I really only like the blue or the green. This is not a complaint as I LOOOVE your app, it’s just a suggestion. THANK YOU.
