This is very challenging. We have a hybrid app that integrated with 3rd party apps, essentially we redirect users to a web-view that they can authenticate their account literally on the 3rd parties website.
At some point one of those sites blocked everything accesses to android less than 5.1, users are still calling us to complain that we have an issue with our app.
TL;DR most of the users cannot tell the difference
Another Hybrid app would be Discourse (open source Internet forum) which essentially opens a native page that you can add forums that use their platform (including the MoT forum). Now if you open the forum directly from your phone you get the option to “install” a shortcut on your home screen, which makes it a Web app.
Camera : Native app because Android Camera isn’t the same app of iOS device, each one has his own options.
Pinterest & LancĂ´me : Progressive Web App because they are websites that look and feel like an app without downloading a mobile app. Moreover, I can add a bookmark on home screen.
Instagram & Facebook: Hybrid because they communicate with the web part
nice selection! And for the camera, you should also keep in mind that some manufacturers have different camera lenses and sensors build in the same device model.
This can happen due to later productions of the phone and maybe the manufacturer noticed some issues with the camera chip and they want to improve their product.
I had once 2 test devices from the same vendor, phone type and OS level and both phones where handling the image processing differently.
Thank you @dnlknott for all those details ! From your opinions, I conclude that Camera is a kind of app hard to put in mentionned types it’s more complicated than normal apps. Or it’s always native although those ambiguities?
