Most apps have sign-up pages, and for an important reason: user experience. Sign-up pages allow the app to create a personalized experience, which is essential for app success nowadays.

In this guide, we’ll explore:

  • Why sign-up pages are an essential
  • How you can add one to your app on Natively

Why Should Your App Have a Sign Up Page?

A sign-up page is where a user’s journey to your app begins. When a user creates an account on your mobile app, they get to access key features to your app. So, every time they use the app, they can pick up from where they left off.

In addition, a user account allows the app to understand their preferences and patterns. It ensures that they get a personalized experience, which is crucial in today’s era.

How to Add a Sign Up Page to Your App?

Any mobile app that you build with Natively is completely functional. You can add any features, pages, and functionalities that you want to your app.

Here’s how you can add a sign-up page to your mobile app:

1. Describe your app

The best part about Natively is that anyone can build apps with it. Start by describing your app in Natively’s prompt box. You can include details on how you want your app’s interface to be, the features and pages you want in the app.

Here’s an exemplar prompt for a demo app:

Every AI model can understand prompts only if you write them by the rules of prompt engineering. You can learn the basics to implement here.
Once you’re done writing, click on the “arrow” and let the AI show its magic. This is what your app will look like:

2. Sign-in to Supabase

While the app’s frontend structure (interface) is ready, it isn’t functional yet. That’s when you need to add a backend structure to your app, such as Supabase.

If you’ve never used Supabase before, you need to sign-up for it and create a new project. Once you’ve signed up, you’ll end up on your first project:

If you already have a Supabase account, you can skip this step entirely and sign into your existing account on your Natively project. Let’s find out ‘how’ in the next step.

3. Connect to Supabase

Once you’ve created a new project in Supabase, you need to connect it to your app to make any use of it.

Click on the “Integrations” button on the top right corner of the menu and choose Supabase.

A pop-up will appear on your screen. You have to log into Supabase your account here.

After you’ve logged in, connect your app to a new Supabase project. It’ll look like this:

Once you’ve connected your app to Supabase, you can add any new functionalities, pages, and integrations to it. Hence, you can also integrate AI capabilities to your app.

4. Write a prompt

The foundation to add any new features and pages is ready at this point. Hence, you can add a ‘Sign-up’ page to your app as well.

To get started, you need to write a short prompt such as, “I’ve connected Supabase now. Create a Sign-up page in this app.” 

This is our prompt on our Demo app:

5. Make any iterations

You need to prompt the AI in the chatbox to make any iterations, add any page and functionalities, or to add any specific capabilities with integrations. It’s the way Natively builds for you — no code needed.
