Apple has released support for even more default iOS apps in the iCloud web console for developers. iCloud Beta has been around since WWDC 2012, and they have just added Reminders and more.
If you have a developer account with Apple, you can use the new beta portal right now. Here's an overview of the new features:
- Find My iPhone has a new look with a battery status indicator for your lost device.
- The Notes app from iOS is now available. It looks the same and doesn't have image support like the Mountain Lion version has been announced to get.
- The Reminders app support has been removed from the Calendar app, where it's currently available and is a standalone app.
