[Showcase] Pomodoro Timer: Building a Sleek, Web-Powered Productivity Tool with App Inventor

Hi everyone!

I’d like to showcase another great project from developer Iago Lira Passos that demonstrates how to create a high-quality productivity app using MIT App Inventor and the WebView component.

This app, Pomodoro Timer, is a minimalist and efficient time-management tool based on the famous Pomodoro Technique. What makes it stand out in the App Inventor ecosystem is how it leverages web technologies to provide a smooth, modern user experience.

The Power of the Hybrid Approach (Blocks + WebView):

While App Inventor handles the Android integration, the core timer interface and animations are driven by a WebView. This approach allows for:

  • Precision Timing: Using JavaScript within the WebView to ensure the countdown remains accurate even when the UI updates.
  • Modern UI/UX: A clean, responsive design with CSS transitions that can be harder to achieve using only native standard components.
  • Custom Notifications: Seamlessly switching between work sessions and break periods with visual and audio cues.

Key Features:

  • Customizable Intervals: Users can adjust focus time, short breaks, and long breaks to fit their personal workflow.
  • Session Tracking: A clear visual indicator of how many Pomodoros have been completed.
  • Clean Interface: A distraction-free environment, which is essential for a focus-based app.

Why this is a great example for the Community:

Many beginners think App Inventor is limited to "basic" looking apps. This Pomodoro Timer proves that by using the WebView as a rendering engine for your UI, you can publish professional-grade, beautiful apps to the Google Play Store. It’s a perfect case study on how to bridge the gap between "Block coding" and "Web design."
