I like making maps, and I wanted to do a certain bend on a very specific kind of online map, filling a gap I noticed in existing maps. The idea of an app really appealed to me (at first), but the more I thought about it the more I didn't want to deal with iOS and then Android and then maintaining parallel functionality on the web and all that mess just for a fairly-local hobby project that I make no money off of. So,…
So i've done similar things in the past - and my justification for 'app' over website has been offline. Does the PWA state of things resolve that in the modern days? If it did, yeah I'd agree, no need for an app at all. In my case the app was being used in rural Ontario. I cant even make a phone call here without wifi.
Gosh, I wish more apps did some kind of progressive "enhancement" and let people read already cached messages and do deferred sends like the old days, instead of being completely useless without a data connection.
