Are you looking for a quick way to create a dynamic, fully customized app—without coding everything from scratch? Meet Deplyr: a powerful app-building platform that integrates seamlessly with Google Sheets (among other data sources). In this post, we’ll walk you through how to create a simple randomized quiz application, and we’ll highlight why Deplyr might just become your go-to tool for all sorts of app needs.
What is Deplyr?
Deplyr is a low-code/no-code platform that allows you to build apps rapidly. It provides:
- Front-end (UI) development
- Back-end actions (code snippets for data interactions)
- AI-assisted code generation
- Seamless integration with popular data sources like Google Sheets and Airtable
- Built-in user authentication so you can make your apps private or public
The result? You can spin up production-ready apps in minutes, customize them to your heart’s content, and share them with a single click.
Watch the Video Tutorial
If you’re more of a visual learner, watch the video below which demonstrates how to build a simple quiz app on Deplyr using the Google Sheets integration and Deplyr’s AI code builder.
Step 1: Integrate Deplyr with Google Sheets
One of Deplyr’s biggest advantages is how easy it is to connect with Google Sheets. You simply:
- Click on the Google Sheets integration button in Deplyr on the Integrations page.
- Follow the consent flow and authenticate your Google account.
Once you’ve done this, Deplyr can read and write to the sheet you specify (using the sheet ID) as you build out your app. This means you don’t need to manually deal with APIs or complex credentials; everything just works after a few simple clicks.
Step 2: Understand the Deplyr App Structure
Every Deplyr app typically has two main parts:
- Frontend (UI): This is where all your design and layout elements live. You can create text fields, buttons, forms, and any other interface elements you need for your application. The frontend is available to you in simple HTML/JS code or you can make edits via the AI chat interface.
- Backend Actions or just "Actions": These are code snippets that interact with your data source (in this case, Google Sheets). For instance, you might have an action that reads quiz questions from one tab, or another that writes a user’s answers to another tab. Actions essentially connect your frontend to your data.
AI Code Builder
Deplyr’s AI can write most—if not all—of this code for you. You simply:
- Describe what you want your code to do.
- Let Deplyr’s AI generate the code.
- If the generated code needs adjustments, you can refine it by talking to the AI in the built-in chat interface.
This drastically reduces the time spent writing and debugging your code.
Step 3: Create Your Randomized Quiz
In the example featured in our video, we'll be doing the following:
- Taking a google sheet that has questions and answers, and a tab for student answers.
- We'll write up a prompt to give to Deplyr to create the app with our requirements.
The Prompt
We will be using the following prompt that describe the sheet and how the app should work. Important, the better and more descriptive your prompt is, the better your outcome will be:
Based on the following google sheet info we want to generate a simple quiz app
Each tab has a header row.
Tab: Quiz Questions
Cols: Question ID Question Correct Answer Wrong Answer 1
Wrong Answer 2 Wrong Answer 3
Tab: Student Answers
Cols: Name Score Summary of Answers
Context: “Summary of Answers” can be a lot of text, basically it should give me Question Id: Answer (each on a newline all within the cell)
The app should work as follows: When it starts the student should enter their name, and then in random order show each question as multiple choice (options A, B, C, and D). The correct answer should also be a randomly selected letter answer. At the end of the quiz there should be a submit button. After the quiz is submitted calculate a score and populate the spreadsheet. Thank the student, but do not display their score.
Creating the App
In Deplyr on the dashboard screen click "Create New App" > "With AI", and then give your app a name and for the prompt we paste in the above. This will generate the necessary code, which in this case is:
- Frontend
- Action: getQuizQuestions
- Action: submitQuizAnswers
Step 4: Save and Launch
After we've created the app with the initial prompt, the app is immediately live. You also have the options to modify the permissions or share the app publicly by using the URL. You can make further edits to the app using the AI chat interface.
More Use Cases with Deplyr
The quiz app is just one example of what’s possible with Deplyr. Here are a few other ideas you can explore:
- Client Portal: Allow clients to view personalized data, schedules, or account info from Google Sheets or Airtable.
- Point-of-Work App (like an inventory logger): Quickly record and view inventory changes in real time.
- Customer Check-In Screen: Automate reception workflows at an office or clinic, storing visitor information in a Sheet or database.
Why Choose Deplyr?
- Easy Data Integrations: Whether it’s Google Sheets or Airtable, Deplyr takes the complexity out of connecting your app to external data sources.
- AI-Powered Development: Get code snippets generated instantly, and refine them through a chat-based interface if needed.
- Instant Deployment: No servers or complex deployments to manage. Save your app and it goes live.
- Flexible Authentication: Keep your apps private to just your team or share them publicly—it's your choice.
