Have you ever thought, “There should be an app for that”? With App Lab, creating your own app is easier than ever. It’s a fantastic tool for beginners in computer science to quickly build apps that they can share and that are meaningful to them. Here are five reasons why App Lab could be a great addition to your learning experience:
With App Lab, you can turn your ideas into a working app prototype in no time. It allows you to see your concepts come to life with just a few steps, making it easy to create interactive projects.
App Lab introduces programming through block coding, which is perfect for beginners who might not be familiar with JavaScript syntax. You can start coding with blocks and then transition to text coding. You can even drag blocks into text, making it a versatile tool for both new and experienced programmers.
You don’t need to know HTML or CSS to create apps with App Lab. In design mode, you can simply drag and drop buttons, dropdowns, and other user interface elements. Once you’ve designed your app, you can bring it to life with code.
Many useful apps rely on databases, which can be challenging for new programmers. However, App Lab makes it easy with built-in data blocks. You can create games with leaderboards, quizzes that store user responses, or apps that let users rate movies, food, or study spots. Using a database opens up a whole new world of app possibilities.
Every app you create in App Lab gets a unique URL, making it easy to share with friends and family on any device. You can send the link via text, and when someone clicks it, they can use your app on their phone.
In our class, we worked in groups to decide what kind of app to create and what users might want. We developed a simple game called “The Boat.” Although we created App Lab for our specific computer science course, it can be used in any introductory programming class. We’re excited to share our work, and you can find more detailed tutorials on our YouTube channel to explore the different features of App Lab.
Imagine an app that solves a problem you face daily. Use App Lab to create a prototype of this app. Start by sketching your idea on paper, then use the drag-and-drop features in App Lab to design the user interface. Finally, add basic functionality using block coding. Share your prototype with the class and explain how it addresses the problem.
Begin by creating a simple app using block coding in App Lab. Once you are comfortable with the blocks, challenge yourself by converting the block code into text code. This will help you understand the JavaScript syntax better. Compare your text code with a classmate’s to see different approaches to the same problem.
Work in pairs to design an interactive app that includes at least three different user interface elements, such as buttons, dropdowns, and sliders. Use App Lab’s design mode to arrange these elements and then write code to make them interactive. Test your app with your partner and gather feedback for improvements.
Develop an app that uses App Lab’s lightweight database capabilities. For example, create a quiz app that stores user scores or a simple survey app that collects user opinions. Use data blocks to manage the information and present the results in a meaningful way. Share your app with the class and discuss the data management techniques you used.
Create an app that you are proud of and generate its unique URL in App Lab. Share the link with your classmates and family members, asking them to try out your app and provide feedback. Use the feedback to make improvements and discuss the importance of user feedback in app development.

There’s probably been a time in your life when you thought there should totally be an app for that. Making your own app has never been easier than it is with App Lab. It’s a powerful tool for beginning computer science students to quickly build shareable apps that are relevant to their lives. Here are five reasons that App Lab could be a great tool for your classroom:
1. **Rapid Prototyping**: Students can go from an initial concept to a working prototype super quickly in App Lab. With just a few actions, students can see their idea come to life and exhibit interactivity.
2. **Blocks to Text**: Coding with blocks introduces students to programming without needing to know much JavaScript syntax. You can code in blocks, you can code in text, and you can actually drag blocks into text! This makes programming approachable for new students and dynamic for more experienced students.
3. **Building Interactivity**: You don’t need to know any HTML or CSS to build these apps. In design mode, you can just drag buttons on, drag dropdowns on—any kind of UI element that you want to add. You can add that and then power it with the code.
4. **Lightweight Database Capability**: In any kind of useful productivity or fun app, it’s almost certain that it uses a database in the back end, which is normally a super inaccessible thing for new programmers to get going. With the data blocks built into App Lab, that’s really easy. You can build games that have a leaderboard across all your users, a quiz or survey that stores user responses for later analysis, and rating and comments on an app that lets you rate movies, food, or places to study. Programming with a database unlocks a whole new class of apps previously inaccessible to new programmers.
5. **Shareability**: Every app automatically has a unique URL, so once students have a working app, they can instantly share it with their friends and family on any device. You can enter your phone number or a friend or family member’s phone number, and it will text the link to them. When they click it, they open it up and are using your app on their phone.
We all worked in groups to decide what we wanted to create and what customers might want to see. The name of the game we built is called “The Boat,” and it’s very simple. We developed App Lab for our particular CS Principles course, but what’s amazing is that it can be integrated into any introductory computer science programming class. We are excited to share it.
