These days everything and everybody wants, needs and makes an app. Stop doing that and focus on making IAPs (in-app purchases), not apps.
By focusing and making more IAPs your code to revenue ratio will start getting better and better. Writing less code, and getting more revenue, that has MDD written all over it!
By adding more IAPs to your apps you don’t need to create more apps and monetize them, you can add more monetization to current products and get more revenue and profits from that single product.
