Learn how to build a simple mobile app without heavy coding. We will pick a clear idea, map 4–5 screens, connect data from Google Sheets, and publish as an APK or PWA. You will see live demos with MIT App Inventor, Thunkable, and Glide. We will cover forms, lists, basic logic, and quick design tips. By the end, you will have a working app you can share. Bring a laptop and a Google account.
