Hybrid monetization is a strategy of combining multiple monetization models in a single app. In most cases, this term describes monetizing with in-app purchases and in-app ads. Additionally, app developers can leverage subscriptions as another revenue stream.
The main strength of hybrid monetization is the ability to monetize a wide pool of players. Instead of relying on a single revenue model, with a hybrid model, developers diversify their income sources. This allows them to cater to different user preferences and behaviors, resulting in revenue from a larger audience.
