Finally finished PayBack. Its a receipt splitting app, you take a photo of the bill, claude reads it, you tap what you ate or bought, and it tells you what you owe.

Features:

• Receipt scanning with Claude vision.
• Manual item entry if you don’t want to use the camera or upload.
• Edit screen so you can fix anything claude misread.
• Split items between people if you shared something
• Tip picker (10, 15, 18, 20%)
• Currency detection and live conversion, it reads the receipt for any addresses/locations on it to figure out what country you live in.
• History saved to local storage

Struggles and Reflection:

The receipt parsing was the annoying part. Receipts are all over the place with tax lines and bag fees and loyalty points and random numbers everywhere. I had to write a really specific prompt to get claude to only pull out the actual items. It was a fun challenge to utilize a Claude api key in a project! I will try to update this more.

Things I want to add in the future:

• A full login/sign up with supabase
• Away to connect a payment system or like on mobile tap to pay (hard but I am sure it is possible)
