Yes, you are able to change your plan by calling or emailing us. Your plan change will become effective immediately upon the next billing cycle.
When you change the design of your app (e.g. color scheme, logos, etc), add/remove modules from your app or want access to new functionality we release we are required to submit an updated version of your app to the app stores for approval. The $99 charge helps us to cover the cost to submit this app update.
