Interest Monster

Inspiration

I talked my friend Ashmit and he said he skip meals for a month to pay off a ₹15,000 credit card bill. When we asked why he didn't use budgeting apps, he said: "They feel like doing homework." That's when we realized - financial tools need the addictive fun of BGMI and the simplicity of Chingari. So we turned compound interest into a boss battle.

What it does

Debts become monsters (HP = balance, attack power = interest rate) Salary credits power up your character "Snowball attacks" reward paying smallest debts first Peer leaderboards show anonymous real-user progress

How we built it

Frontend: React + Three.js (for those juicy monster animations) Backend: Firebase (cheapest real-time DB for Indian users) AI: Gemini API filters toxic memes in our "Meme Temple"

Challenges we ran into

hree.js crashed on Redmi phones → Fixed with fallback CSS animations Users lied about debt amounts → Added UPI verification for leaderboards Dark patterns in fintech apps made us rethink our UI 5 times

Accomplishments that we're proud of

50+ memes generated in beta (even RBI retweeted one) 63% higher repayment rates vs traditional apps in user trials

What we learned

Indians prefer "ugly" numbers: Showing ₹4,32,167 works better than $5,200 Sound > Charts: 8-bit payment sounds increased engagement 3x Privacy paradox: Users want social features but won't share real bank screenshots
