Setting Up Your Adalo Workspace

Adalo workspace interface

Create an Adalo Account and Start a New Project

Head over to Adalo's homepage to create a free account—no credit card required. The sign-up process takes just a few minutes, and you'll gain instant access to the builder interface. Once logged in, use the app selector dropdown to click "Create New App" and kick off your first project.

You'll choose between two layout options: "Mobile, Tablet, and Desktop" (responsive) or "Mobile Only". For beginners, "Mobile Only" offers simplicity, but for this guide, select "Mobile, Tablet, and Desktop" to create a fully responsive app from the start.

Give your app a name, assign it to a team, and pick initial branding colors (you can adjust these later). With that, you're ready to dive into building.

Before jumping straight into design, take a moment to outline your app's goals and structure. A clear plan makes the design process significantly smoother and helps you avoid rework later.

Define Your App's Purpose and Structure

Before opening the visual editor, clarify your app's purpose. Adalo offers two approaches to define your app's structure: Magic Start AI or pre-built templates.

With Magic Start, type a plain-language description like "a booking app for a dog grooming business." The AI generates a complete foundation for your app—including database structure, screens, and user flows—within minutes. What used to take days of planning and wireframing now happens automatically, giving you a solid starting point that you can customize to your exact needs.

If you'd rather not use Magic Start, Adalo also provides a library of nearly 40 templates. Popular options include:

These templates come with pre-designed screens, logic, and database setups, making it easier to understand how components work across different device sizes. This is especially helpful when you're getting familiar with responsive design principles.

Once your project is set up, you'll enter the builder interface. The central canvas is your workspace for dragging and dropping components. On the left-hand side, the Editing Dashboard gives you access to screens, components, integrations like Stripe, and other customization tools. The builder can display up to 400 screens, giving you a complete view of your app's architecture at any time.

Designing Responsive Screens with Adalo's Visual Editor

Using Drag-and-Drop Components

The visual editor keeps things simple with intuitive drag-and-drop functionality. From the Editing Dashboard, access core components like buttons, forms, text fields, images, and lists. Click on the component you need, drop it into your design, and customize its appearance and behavior using the properties panel.

Want to tweak colors? No problem. Need a button to navigate to another screen? Set that action up in seconds. If you're working with data, drag in a "List" to display database feeds or add a "Form" to collect user input directly into your collections.

This intuitive interface has empowered creators to build over 1 million apps—all without writing a single line of code. Since the platform uses a single codebase for web, iOS, and Android, every component you add works seamlessly across all platforms. You won't have to rebuild your app for different devices or maintain separate codebases.

Once your components are in place, it's time to fine-tune their layout for various screen sizes.

Making Your Layout Work Across Devices

After setting up your components, ensure your layout adapts smoothly to different devices.

The responsive builder includes three breakpoints: Desktop (992px+), Tablet (768px–991px), and Mobile (up to 767px). Use the Screen Size Switcher at the top of the builder to preview how your design will look on each device type.

By default, components follow Shared Layout settings, meaning any layout changes apply across all screen sizes. But what if you want a different arrangement—like stacking buttons vertically on mobile but aligning them horizontally on desktop? Simply disable Shared Layout for that screen size to switch to Custom Layout mode. This lets you adjust positioning, scaling, and anchoring independently for each device type.

A mobile-first design approach works best. It ensures components don't overflow or misalign when viewed on smaller screens. To make adjustments easier, use Rectangle components as containers to group related elements like text, images, and buttons. This way, you can move entire sections as a unit when refining layouts. Additionally, visibility toggles allow you to control what users see based on their device—like showing a full sidebar on desktop but replacing it with a compact menu icon on mobile.

Building Logic and Database for Dynamic Functionality

Creating and Managing Collections

Data in Adalo is organized into Collections, which function like tables in a database. Every app includes a default Users collection that serves as the foundation and cannot be removed. Beyond this, you can create additional Collections tailored to your app's needs. For example, a marketplace app might require Collections like Products, Orders, and Reviews, while a fitness app might rely on Workouts, Progress, and Goals.

To set up a Collection, head to the Database tab (the red icon), click "Create Collection", and assign a name that reflects its purpose. Next, define the properties for the data each record will hold. The platform supports various property types, including Text, Number, True/False (boolean), Date/Time, Image, and File. Images and files have a 50MB limit, while the Number property accommodates up to 15 digits, including decimals and negative values.

Relationships allow you to link Collections, enabling more complex data structures. For example, a one-to-many relationship works well when a single user can create multiple posts, while a many-to-many relationship suits situations like events with multiple hosts. As you set up relationships, rename the related properties in both Collections to keep your database organized as it grows. You can populate Collections manually, import data via CSV files, or let users contribute by submitting records through Forms.

One significant advantage: paid plans include unlimited database records—no caps on how much data your app can store. This removes the scaling constraints that plague many competing platforms, where you might hit record limits just as your app gains traction.

Once your Collections are ready, you can move on to building interactivity that makes your app dynamic and engaging.

Adding Actions and Filters for Interactivity

With your data structured, the next step is bringing your app to life using Actions and Filters. Actions define the logic triggered by user interactions. For instance, when a user clicks a button or submits a form, Actions like "Create Record" (adding new data), "Update Record" (editing existing data), "Delete Record" (removing entries), or "Navigate to Screen" (switching pages) are executed.

Adding a Form to your app is straightforward. Drop a Form component onto your screen, link each input field to its corresponding Collection property (e.g., connecting an email input to Users.Email), and set the Form Action to "Create" a new record in the Users Collection. For a polished experience, you can add visibility conditions to show a success message after submission, ensuring the process feels seamless across iOS, Android, and web platforms.

Filters make your app dynamic by tailoring content to each user. Filters query your Collections in real time, displaying only the relevant data. For example, in a social feed, you might filter the "Posts" Collection to show content from "Current User Followers" where the User matches the current user. Pair Filters with Actions for added interactivity—like a "Like" button that updates a post's like count while refreshing the list in real time. This approach ensures responsiveness without requiring backend coding.

The platform's infrastructure handles 20 million+ daily requests with 99%+ uptime, so your database queries and filters perform reliably even as your user base grows. Unlike platforms that charge based on database operations or impose record limits, you get predictable performance without worrying about usage-based billing surprises.

Testing and Optimizing Your App for Responsiveness

Adalo provides tools that combine performance analysis with cross-device testing, making it easier to ensure your app is both responsive and efficient before you publish.

Using X-Ray AI for Performance Analysis

X-Ray AI evaluates your app's performance and assigns it a score between 0 and 100. This score reflects how well your app performs in terms of speed and reliability across devices, helping you identify and address issues before users encounter them.

X-Ray focuses on three key areas:

When X-Ray detects issues—such as overloaded lists or large image files—it suggests actionable fixes, like optimizing filters or compressing media. This proactive approach helps you build apps that scale smoothly as your user base grows.

To test your app's responsiveness, use the Screen Size Switcher in the builder's top-left corner. This feature lets you see how your layout adjusts across different breakpoints. For example, you can spot and resolve issues like text overflowing on mobile screens or buttons disappearing on tablets in real time.

These tools allow you to fine-tune your app so it performs consistently across all devices before going live.

Previewing and Testing on Multiple Devices

Once you've addressed performance bottlenecks with X-Ray AI, the next step is to preview and test your app on various devices.

Adalo offers two preview modes through the Preview button:

These modes allow you to experience your app as users would on iOS, Android, and the web. You can also test your app's behavior on desktop, tablet, and mobile breakpoints using the Screen Size Switcher or by manually setting a custom width. Be sure to test both portrait and landscape orientations for a complete picture of how your app behaves.

For more precise testing, use Responsive App mode with browser simulation tools to mimic specific device resolutions, such as an iPhone SE or iPad Pro. A mobile-first approach—designing for smaller screens first and scaling up—can help avoid issues like desktop layouts spilling over on mobile. Additionally, grouping related components inside a Rectangle component ensures layouts stay consistent as screen sizes vary.

Device Type Screen Width Testing Focus
Mobile Up to 767px Touch targets, text readability, vertical scrolling
Tablet 768px – 991px Two-column layouts, navigation transitions
Desktop Over 992px Multi-column grids, expanded navigation

When you're confident in your app's performance, publish it and share the URL for broader testing. Since the platform builds one app that works seamlessly across iOS, Android, and the web from a single codebase, any improvements you make will apply across all platforms automatically, saving you time and effort.

Publishing Your App to Web and App Stores

Once your app has been thoroughly tested, it's time to bring it to life by publishing. Adalo's unified build system allows you to deploy your app to the web, Apple App Store, and Google Play Store—all from a single build.

Generating Native Builds

The platform simplifies the creation of native builds for both iOS and Android. Head to the Publish tab in your app dashboard and choose either Native App for mobile platforms or Web App for browser deployment. Before starting, ensure you've uploaded essential assets like app icons (1024x1024px) and splash screens. If anything is missing, the dashboard will notify you.

When you're ready, click Generate Build, and the system compiles your app into the appropriate native files: an .ipa file for iOS and either an .apk or .aab file for Android. Publishing to app stores requires a paid plan starting at $36/month—the lowest price point for native app store publishing among major platforms. Web publishing is available for free, making it easy to test your responsive web app before committing to mobile deployment.

The same project you use to create mobile builds can also deploy as a responsive web app. Simply select Web App in the Publish tab, set up your domain, and deploy instantly. This unified approach means you maintain one codebase while reaching users on every platform.

Submitting to App Stores

For the Apple App Store, you'll need an Apple Developer account, which costs $99 per year. In the Launch tab, enter your Bundle ID, Apple ID, and App-Specific Password. Keep in mind that Apple requires sign-ins to be approved from a Mac, iPhone, iPad, or Apple Watch with two-factor authentication enabled. Once ready, upload your .ipa file via App Store Connect, including screenshots, privacy labels, and release notes. Following Apple's Human Interface Guidelines and testing your app's responsiveness can help increase your chances of approval.

For Android, log into the Google Play Console, which has a one-time registration fee of $25. Upload your .aab or .apk file, then complete your store listing with descriptions, graphics, and content ratings. Make sure your app targets the required SDK version. The platform handles many technical details, like signing keys and image optimization, to help you avoid common errors. After submission, Apple typically reviews apps within 1-7 days, while Google Play approvals often happen faster.

Manual publishing is also available, allowing you to test updates without affecting your live app. When you're ready to release a new version, regenerate your build with a single click and resubmit to the app stores. For web apps, updates are instant and don't require store approval, making it easy to keep your app fresh and up-to-date.
