To develop applications for Alpha 2, you should register as a “UBT developer”. If you already have a “UBT account”, you can login here. Then, fill in your information as a developer and complete your registration as a developer. Of course, you can also register for a new developer account.
When you have registered as a developer, you can create an app for Alpha 2. Then, fill in your application information and hit "Submit".
Once submitted, the app will enter the "Create" stage. When you have completed the development of the app, hit "Create" to proceed to the next stage.
You can rename the app before publishing it and must upload your app icon. After submitting your app, you will enter the "Review" stage.
Congratulations! Once reviewed, your app will be downloaded and used by UBT subscribers worldwide at app stores.
