The Traffic Light for Your Wallet 🚦
The only budgeting app that gives you instant visual spending guidance. No math, no stress, just a simple color that tells you exactly what to do.

How the Traffic Light Works

> $500
Your Safe to Spend is above $500. Feel confident making purchases - you're in a healthy spot!
Yellow Zone: Mindful Spending
$0 - $500
Between $0 and $500. You can spend, but be thoughtful about each purchase.
Red Zone: Spending Pause
< $0
Below $0. Time to pause non-essential spending until your next paycheck.
