Will apps ever stop being subscription-based?

Today I bought a keyboard to start my journey of learning the piano. I had my first lesson on Saturday and from now on it’s about doing it regularly for the next decade or two. But today’s blog isn’t about the pursuit of being a pianist. It’s about how sad the app industry is.
I remember almost a decade ago when apps were slowly becoming an important part of our lives. If you were an android user you were in more luck compared to ios users. Why? Because of the availability of better apps? Not really. IOS always had better app support. But if you were an android user you had the chance to download apks of any app you wanted even if you didn’t purchase the pro versions, you could get the apk. While I don’t support doing that now, I wouldn’t deny that I did that myself in the past. But it’s not about the apks or getting paid apps for free. It’s about how app pricing has changed.
During that time if you liked an app and wanted all the features, you could just buy the pro version. Just buy it for a fixed price. Plain and simple. You get your feature, the developer gets their money. But now everything has switched to subscription models. For most of the apps I like and I want to get the full version I have to subscribe to. Subscribe! I have to subscribe to use an app! Why can’t I just get the full version for a fixed price? How many things should I be subscribing to?
Sorry for venting out. If this model benefits the developer, especially those who are individual developers then definitely this is the way to go. But as a consumer, it is frustrating how things are changing.
