How This 17-Year-Old Quietly Built a $1.12M/Month AI App
I stumbled upon his exact strategy from A to Z and it's brilliant.

Meanwhile, Zach Yadegari is quietly crushing it. He’s the mind behind Cal AI, an app that tracks calories using a simple photo. No logging. No spreadsheets. Just take a picture, and boom — calories calculated.
When I heard about this, I had to know: How does a teenager build something like this? Turns out, Zach didn’t stumble into success. He engineered it, step by step.
