Even simple apps nowadays have become subscription only. Whilst I used to pirate most stuff in the past, but if the app in question is a small one time purchase, it’s not bad considering you don’t need to sideload updated apk’s from Mobilism each time a new version is released (looks at some great cheap apps like Pano Scrobbler).
However, the trend has shifted towards the other side with everything from video recording apps(AZ Recorder), Weather apps(Today Weather) and Battery monitoring apps(Battery guru) offering subscriptions. Some have a high one time purchase option but some like the latter don’t.
Battery Guru is an example of enshittification. If phones still came with removable batteries and companies supported them, then for the price of say, a 4 year subscription to the app, I could have just gotten a new replaceable battery. It’s not like the app will magically stop my battery from degrading.
Whilst I have done piracy ( and still pirate stuff like films because no alternative, screw you Netflix), I tried to go the legal route for some apps since then updation and management of them becomes easier. But with the subscription scourge, I doubt devs are going in the right direction.
I don’t know where you’re getting Pano Scrobbler from. But I install quite a few apps through Obtainium. You can paste the link to e.g. the github page and it will automatically install and update your app. Obtainium is on Fdroid or you can get it from github aswell.
I use Obtanium actually since my main mobile browser is Iceraven which isn’t on F-Droid by default. [It supports sideloading extensions that official Firefox doesn’t].
IIRC, Pano Scrobbler is free but has a premium version as well on Google Play. I scanned through their Github and as of August 2024, the dev was working on implementing payment features without Play integration [like donating to the app and then getting a key for it which will be validated against license servers]. I used to sideload Premium variant of Pano Scrobbler before from Mobilism.
