One effective monetization strategy for mobile apps in 2024 is implementing a freemium model, where the app is free to download but offers premium features or content for a fee. A great example of this is the popular meditation app Calm, which offers a free version with basic meditation sessions and mindfulness exercises, but also has a paid subscription option for access to a wider range of content, including exclusive sleep stories and guided meditations. This strategy allows users to try out the app before committing to a purchase, increasing the likelihood of converting free users into paying customers.
