GroceryTrip – Turn receipts into nutritional information
Hey HN, I've been working on a Flutter app for the past few months that turns receipts into useful nutrition information. The aim of this project is to make it easier to understand the nutrition and ingredients in our groceries simply by scanning a receipt. How GroceryTrip works (more detail in github repo): 1. Take a photo of your receipt (remains local, there's a demo receipt in the app if you don't have one on-hand) 2. Crop photo to relevant barcodes/names of products 3. View receipt Summary/Details 4. Optional: Contribute missing barcodes It's a super simple app currently, but…
In plain words
GroceryTrip is a Flutter app that extracts nutritional information from grocery receipts. Users photograph their receipt, crop it to show product names and barcodes, then view detailed nutrition and ingredient data for items purchased. Photos are processed locally on the device. The app allows users to contribute missing barcode data to expand its database and tracks grocery purchases over time to identify dietary patterns.

I saw this [0] pretty cool thread by user revskill, and wanted a quicker way to search through it, but also to keep them all in one place so I can read them at my leisure whenever I get time. Right now is like 60 lines of Ruby using Nokogiri, but I will certainly look into it further down the line and improve the list. There's a cronjob checking the thread every 12 hours but I will eventually shut that down and it will become static after that. There are some really awesome blogs in there. I really recommend going through the list, it made my day. [0] "Could you share your personal blog…
