The “Zero-API” Template Bundle

Master Hybrid Coding, CloudDB, and Native Features with 5 essential templates. No API keys required. Import and run immediately on your Android device..

Introducing: The App Inventor 2 “Plug-and-Play" Template Set

We have selected 5 high-quality, proven templates from our library. These apps use Advanced Logic, JavaScript Integration, and CloudDB — all without requiring a single external API Key.

What’s Inside the Bundle?

Space Invaders Game (AI + JavaScript in WebViewer)

Featured on our YouTube Channel!

  • Tech Stack: WebViewer + JavaScript (Written by Gemini 3 Pro)
  • What makes it special: Witness the power of Generative AI. This template demonstrates exactly how we used Gemini 3 Pro to write complex game logic in JavaScript and run it smoothly inside App Inventor.
  • Why you need it: This is the future of No-Code development. Learn the “AI Hybrid" workflow: Let AI write the complex code, and use Blocks to control the app.

Tic-Tac-Toe Online App (CloudDB)

Build a real-time online game in minutes.

  • Tech Stack: CloudDB
  • What makes it special: Experience instant data synchronization between two devices. Best of all, it uses the default CloudDB server, so no external API keys or server setup is required.
  • Why you need it: The fastest way to learn multiplayer logic.
  • ⚠️ Important Requirements:
    • Two Android devices are required to play against each other.
    • Please Build the APK to test this app. (Real-time connection may not work correctly inside the AI2 Companion).

Pronunciation Practice App (Native Features)

Tap into the global language learning market.

  • Tech Stack: Native Speech-to-Text & Text-to-Speech
  • What makes it special: A clean, educational app that utilizes the device’s native OS voice capabilities. No plugins, no Google Cloud configuration, and zero setup.
  • Note: The default setup uses Italian words and the language code (it). You can easily switch this to any language by replacing the vocabulary list and changing the language code (e.g., to en or es) in the blocks.

Shopping List App (TinyDB)

The foundation of every practical app.

  • Tech Stack: TinyDB (Local Database)
  • What makes it special: Learn the essentials of Data Persistence. Input data, close the app, and open it again—your list is still there.
  • Master the basics of adding and removing items while keeping data saved locally. A perfect introduction to local storage without internet dependency.

Basic Calculator App (JavaScript in WebViewer)

Stop writing messy logic blocks.

  • Tech Stack: JavaScript Calculation Engine
  • What makes it special: Instead of using hundreds of blocks for math, this app uses a smart JavaScript engine to handle complex calculations (like parentheses and order of operations) effortlessly.
  • Why you need it: Learn how to offload complex logic to a few lines of code, keeping your blocks clean and maintainable.
