We don't transfer our apps to other developers.
We are able to transfer your app name, should you wish to create a new app elsewhere but retain your name.
We can also assist in transferring your app profile on iTunes, but not the app itself, should you wish to retain your user base but use a new app.
On Google Play, you will need to alert your users of the need to install the new app. We are unable to transfer the user base to the new app without compromising our database.
