an iOS bill-splitting app for ad hoc, casual events like group dinners

when I ate out in college, the general practice was for someone to front the bill and request payment based on what people ordered. between the receipts, the calculator apps, and the venmo requests, it was a pain, especially if people shared dishes or were covering someone for their birthday. I wanted to cut away every possible inefficiency in the process.

Pita

getpita.app

I created my own algorithm to parse the receipt text OCR. when GPT text models became mainstream a year later, I retrofitted the app to help with the edge cases, as receipts are notoriously unstandardized and often have weird creases that throw off text recognition. when GPT vision models emerged later on, I realized that if I were to build pita today, it would basically be a GPT wrapper 🥲
