Sure, if your app has something worthwhile to do offline.
It allows you to download Patreon-exclusive videos for e.g. viewing it on a flight, similar to how Youtube does it. It's literally the only reason I have it installed as an app.
I've never seen a PWA do that feature well.
PWA also work offline.
a) does it actually work offline (seems unlikely for a payment app, although I guess it could batch stuff)?
b) if so, does it work any better than a web app can offline?
