As I continue to study the mobile app market I have noticed that the "freemium" model is best and most popular. By definition:

Freemium is a pricing strategy by which a product or service (typically a digital offering or an application such as software, media, games or web services) is provided free of charge, but money (premium) is charged for additional features, services, or virtual (online) or physical (offline) goods.

When you begin building out your app create features that can only be use as a paid add on. Many marketers call this the "hook and bait" but I hate that term. I look at it as given people the opportunity to experience your app if they like it enough they will be incline to get more of an experience by paying for it and rightfully so.

If you want to go over some other idea I'd love to chat on a free conference call: https://clarity.fm/settings/expert/vip-link

Either way wish you the best!
