- The author built a simple app called D-investments to teach his kids about investing using just one HTML file.
- The app is a Progressive Web App (PWA) that displays daily, weekly, and monthly gains based on initial investment and interest rate.
- Instead of physical gifts, the author encouraged his son to ask for money to start his first investment.
- The app is installed on an old smartphone mounted on the fridge, acting as a dashboard for tracking investments.
- The goal is to visually demonstrate the power of compound interest and the value of money over time.
- The app includes a configuration screen to input names, invested amount, interest rate, and start date.
- The author acts as the investment agent, setting realistic interest rates to motivate the kids.
- The app is easy to install—just open the link on a smartphone and tap 'Install'.
