The Problem

It’s hard to be on debt and at the same time keep track of your finances. I found myself in that position, hence I built this app. It helps you keep track of any extra payments you make to your loan, so that you avoid interest as much as possible!

The Solution

Loan Calculator is a streamlined mobile application, which is easy to access and use. With just some basic data about your loan, the app gives you a nice, easy-to-understand graph that is accurate with your amortization schedule.

Technical Details

  • Frontend + Backend: Flutter and Dart
  • Graphing Utility: fl_chart for Flutter
  • Deployment: Google Play Store

My Role

As the solo developer on this project, I handled all aspects from initial concept through design, development, testing, and deployment. While it’s still under development, I’m working closely with a small group of beta users to refine the experience through multiple iterations.

Key Challenges & Solutions

Challenge: Displaying an accurate graph for amortization.

Solution: Created custom mathematical formulas to calculate the amortization schedule and used the fl_chart library to display the data in an easy-to-understand graph.

Challenge: Creating nice, easy-to-use UI.

Solution: Used Flutter’s built-in widgets, the Material library and custom widgets to create a clean, intuitive interface that is easy to navigate and understand.
