To each their own, but I find this decision really misguided.
It's her money, not mine, so whatever, but l do not expect her to turn a profit in, rather the opposite.
In my view, the cross section of "IfR" users and people willing to subscribe monthly is rather small (especially if the money mostly goes to reddit - assuming I could afford it, I, for instance, would rather fund an open system like Lemmy).
And if Apollo's dev Christian Selig decided that it wasn't worth it with an already established paying user base, who already has a strong culture of subscriptions and exaggerated pricings, and one of the highest volume of users, at what probably was the peak usage of the platform; I don't see how a small app like IfR can survive.
That, or Christian made a pretty expensive mistake...
There's no way to be profitable with this pricing. Simply no way. Each time an user opens the app it will cost 2 cents in API requests. Continue scrolling, open threads and the costs rises. In average, accounting all the lurkers, inactive and free users, it might look like that it could be supported by a $2 subscription. But then, who is willing to subscribe to an app to read a free website? Only the most addicted users. The ones that will doom scroll for hours. The ones that will do 10000 api requests per day
Also, the server backend must be rewritten from scratch. Right now the app is open source and it's talking directly to the reddit servers using the API key. After the change, it could continue to do so, but because extracting the API key from the APK is trivial, some asshole could extract/crack it and give her a massive bill
Every single request must be proxied by her own server, making a check for a valid subscription to each user and also some quota management. Possibly some caching to save money on the most popular posts. Otherwise it will be trivial for some asshole to make a revanced patch to bypass the subscription. But implement this takes months, she can't have done this and tested carefully in just two weeks
Please someone let her realize this before she gets a massive bill at the end of the month, i don't have a reddit account for that
expired
It's OAuth. Each user that allows access to the app will have an individual token only valid for that app and only for that user's account. Either the developer or the user can revoke that token at any time.
All the dev has to do is to not create/send a token to the user until they subscribe, then revoke that user's token if the subscription expires.
