Preferred Subscription Model in Mobile Apps: Pay-per-use, Monthly or Annual Subscription?

Hello, fellow Product Hunt community members! My name is Anastasiia Veselova, a Product Strategy Researcher currently exploring diverse aspects of mobile app monetization. I am keenly interested in understanding how users perceive different subscription models and their overall preferences. This research will contribute to my understanding and provide valuable insights to developers and businesses alike. One critical aspect that I am focusing on is the type of subscription model users prefer in a mobile application and why. There are mainly three models: 1. Pay-per-use: You pay only for what you use. This model tends to be more flexible but might end up being more expensive depending on the frequency of usage. 2. Monthly Subscription: A fixed fee is charged monthly, offering unlimited access to the app. It's a more stable model, but some might find it unnecessary if they don't use the app frequently. 3. Annual Subscription: Similar to monthly but charged yearly. It's often cheaper in the long run, but it requires a more significant upfront commitment. Each of these models comes with its own advantages and potential downsides, which might affect users' decisions to opt for one over the others. Hence, I would appreciate it if you could share your preferences and why you chose.
