This isn't an alternative for the user (the person you're replying to).
replyI can't think of a web app that really feels like a (good) native one. For example, I would never use Google Calendar as a web app / Google Maps as a web app as they're far inferior IMHO
replyI used Home Assistant as a web app for years before deciding to download the companion app instead to give it access to my phone's sensors.
replyI used to care a lot about app designs feeling "native" but when I actually took inventory of the apps I use, I came to the conclusion that all app developers (including Apple and Google themselves) will force their own designs and theming into every app. The only exception seems to be coming from a bunch of open-source apps that don't have branding concerns to worry about.
With the realisation that most apps look and navigate must as bad as their website equivalent, I found it much easier to use web apps.
