Good calendar app

I really like this app. Simple to use with multiple views and it integrates my calendars. I give it 4 stars since my entries for the current day dont always show up in my notifications. I can open the app to see it but not when I swipe to get a quick view on my phone. Its syncing from MS Exchange so not sure if its Outlook, Apple or the app. Sometimes it works and sometimes it doesnt.
