Inspiration

Managing finances can be overwhelming, especially for students, families, and low-income groups who lack access to professional tools. We wanted to create a simple, beginner-friendly, and accessible finance tracker that empowers users to understand, manage, and improve their spending habits—right from their browser.

What it does

FinWise is a personal finance web app that allows users to:

Log income and expenses

Visualize spending with pie charts

Track balance and categories over time

Export data as CSV

Log in securely to access personalized data

Get financial tips for smarter decisions
