Most native apps also have inconsistencies, lags, delays, especially if they connect to some remote web service. Heck, the iOS settings occasionally hang on my phone when I open the iCloud settings or if some Bluetooth device isn't correctly pairing or whatever.

I've seen beautiful native apps that require an internet connection all the time, because they save every little piece of data on a remote server and sometimes, the whole thing is super unresponsive.

For the muggles, this lag is a lot more noticeable than a transition or a button press that is not 100% optimal.

My Ionic app uses PouchDB and CouchDB, is offline-first/local-first and is responsive at all times, because it simply doesn't care if it is online or not. This is what users feel the most and it can feel a lot better than many internet-connected native apps.
