Sync for iCloud Calendar APK 13.4.5

5 stars: 5 star for the developer. The app does what it can with the
5 stars: Syncs iCloud calendar. When it asks you to create an account, that actually means login. Also don't use your iCloud password.

You can do it from within the app. This is clearer and easier to use than the smoothsync app that doesn't work as well.
4 stars: Recently purchased an Amazon fire tablet to replace my aging iPad, so wanted an App that would sync my iCloud contacts and calendar. This App was easy to install and set up. The only issue I have is every day I get
4 stars: Almost a 5 star review, but for some reason it suddenly stopped syncing and all my events disappeared. I logged in again,generated an Apple app specific password and had to give the account a new name in the app and everything came back. Very strange. Apart from that, this is an excellent app and works very well. Syncs both ways and has been very reliable apart from that one strange occurance. Hope it is a one off problem.
3 stars: Login process is really unclear so I had to come to the reviews to find a solution! Bad UX. Login doesn't need to be @icloud or @me as it states. You're not logging in with your icloud credentials! Just the email address. You need to generate an app specific pw in icloud web in Account Security. Aside from this confusion, it works great when you get it going!
