Sunrise Calendar is an app (and website) that helps you keep track of all your calendar events in one place. The app works with all major calendar providers, including Google, iCloud, Exchange and Office 365. With Sunrise, you can quickly and easily add, edit, and delete events, set reminders, and share events with others. The app also offers multiple view options, including day, week, and month, as well as custom views that allow you to see only specific categories of events. Additionally, Sunrise lets you personalize your calendar with different colors, fonts, and backgrounds, and you can also sync events from other apps, like Evernote, Trello, and Asana. With Sunrise, you can keep your calendar organized and up-to-date, no matter how many different sources you use to manage your events.
Sunrise allows (more) third-party application integrations, while google calendar does hardly anything
