Duplicate Apple apps and features using Android and Windows

[Chuckanut]

One of the great things about Apple is that it has done a great job of integrating its apps accross product lines: information entered on Notes, Calendar, Contacts, etc. is available on the Mac, iPhone, iPad, and Watch via iCloud syncing.

If I ditched my Mac and iphone and iPad over the next few years, how would I duplicate that using Windows and Android? What apps do you use that function across the various platforms and sync data together? I am thinking of thinks like Evernote for example.

Any other ideas?

Google apps on Android such as Calendar, Contacts, and a few others sync across my phones and MacBooks, and iMac.
