AppMobi's Yang is here. I hope I can answer your questions.
First, Google and Appple have their own expenses that need to be sent to the app store. For Android it is $ 25, for iOS - 99 dollars. This requirement is submitted to Appstores and is not affiliated with AppMobi. If you intend to use your own SDK or any other tool, you still have to pay these costs.
Now, for the cost of AppMobi. If you use AppMobi XDK (not Phonegap or GameXDK), then the build cost is nothing. You can create an application for Android or iOS for free. We charge for cloud services such as push messages, statistics, etc.
PhonegapXDK and GameXDK really require what we call "pro packs" to build. This is due to the fact that we offer additional functionality not found in our base XDK or base containers.
