Demo Account for App and Review:
Before publishing your app on the Google Play Store and Apple's App Store, it must undergo review. In this step, creating a demo account is a must so that verifiers in Google and Apple can use it to access and evaluate your app. Once the review process is complete, your app will move closer to becoming available in the stores.
Your email must be unique and not already registered in the app.
Enter the country and the email address and click ‘Verify’.

A verification screen will pop up; check your email, enter the verification code sent to you, and click 'Verify'.

Signup Registeration Form

The Signup Registration Form allows app owners to collect additional user information during the signup process. After users log in through any verification method—whether by mobile number or email—app owners can present a customized registration form to capture extra details and gather more meaningful data, such as demographics, preferences, or business-specific information.
These extra fields will appear in each user’s profile.
You only need to turn the toggle on and click the settings icon.
Image without caption
This is where you design your registration form. Similar to creating a Custom Component, you can simply drag and drop elements into the form area to build the fields you need.
Fill in your form and click ‘Save App Config’.
