Providing premium features is another smart way to make money off of mobile apps. This entails giving away a basic version of the app for free & charging a one-time or ongoing feerummyleader for extra premium features or content. Advanced functionality, access to unique content, ad-free experiences, & more customization choices are examples of premium features. Developers can use this tactic to draw in a lot of users with the app's free version and then turn a portion of those users into paying customers by providing useful premium features.
