The current trend of subscription models for simple applications frustrates users who prefer one-time purchases. Many applications start off simple, only to evolve into complex systems that detract from their original purpose. Users value straightforward functionality and prefer to pay a one-time fee for essential features, rather than ongoing subscriptions. While developers face challenges in maintaining revenue through one-time payments due to processing fees and the burden of continual updates, there's a clear market preference for options like limited-time updates followed by a one-time fee for further access. Flexible pricing models that allow users to choose payment based on their needs could lead to better user satisfaction and engagement.
