does ios 16.5 still meet requirements Of 16.3? My glucose monitor requires 16.3

iOS 16.5 incorporates any updates that occurred in iOS 16.3.

But.....the monitor app that you are using may not have been updated yet for iOS 16.5. That would be up to the support folks for the app that you are using.

Generally, yes. If you find that a specific application is compatible with 16.3 but not 16.5, contact its developer.
