How to create account and use it in the mobile application?

I downloaded the app from the Apple App Store. It asked me for user name and password eventhough I have ever used it before. It does not give me an option to register new account/user. 

Any idea what I can do? 

Please go to https://www.jotform.com and create the account:

When you create the account, you can use it in your mobile app.
