I want to create complication like native Battery one (Circular Ring).

How can I fetch live data for the complications, maybe API call, or data from iPhone? -

• Use WatchKit.framework to do this and use WCSession class to perform the session talking between the phone and the watch.

• You could also use the background tasks API introuduced in WatchOS 3 to make API calls in the background - https://developer.apple.com/library/content/releasenotes/General/WhatsNewInwatchOS/Articles/watchOS3.html

• To update complications in watch OS 3 - https://developer.apple.com/reference/watchkit/wkapplicationrefreshbackgroundtask

No you cannot, one app can have only one type of complication.
