Developing your app won't cost you a penny. AppMachine gives you the freedom to create multiple versions of your app so that you can ultimately choose the best version of the app for publishing. You only pay once you choose to "Publish" your app in the app stores (either in the Google Play store, Apple's App Store, or both). The price is dependent of the subscription you have used to create the app. Once your app has been published, you will receive free unlimited updates to the app. Check our pricing page for more information.
