Girl Math started as a weekend project when I realized my girlfriend was terrible at saving money but amazing at justifying purchases with elaborate mental gymnastics.

Then I thought: what if that same creative energy actually helped you save?

The app turns "I didn't spend" moments into visible progress toward things you really want. Set goals, log tiny wins in seconds (skipped a latte, walked instead of Uber), and watch a satisfying progress bar fill up with haptics, confetti, and a playful receipt at 100%.

Under the fun, it's a habit loop: immediate dopamine for the right behavior, one active goal for focus, and daily micro-wins that build real momentum. No spreadsheets, no guilt trips. Just making your small choices feel like they add up to something bigger.

Runs entirely on-device with no accounts or tracking. Just you, your goals, and your wins.

I'd love your feedback, and if you've got a favorite girl math moment, drop it below so I can add more examples to inspire users ❤️
