Slack's desktop app is a web view. The iOS app is native.
I think the wells fargo banking app on the phone is not native. The At&t one doesn't feel like it. Usually there's something different about the controls and interactions that make it not feel native. Sometimes there's a dead giveaway like being able to double tap and accidentally zoom in just like in mobile Safari.
Yep! A common pattern is for the navigation to be written in the native language to take advantage of faster/smoother animations and all dynamic content is inside of web views.
Spotify on Linux: clicking on things often feels slightly janky and laggy. How fitting!
And the spacebar will 80% of the time page down rather than pause the music, something which sounds minor but which makes the user experience 50% more annoying for me. Do most people even use spacebar to page down in normal webpages!?
The colloquial definition of a native desktop application is an application that runs from a binary on your system. So yes, most people DO think of these as native applications.
