GroceryTrip – Turn receipts into nutritional information

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.

In the maker’s words, at launch

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…

  Hello HN, longtime lurker, finally I have something to show :) IngrediCheck is a Food Scanning App. It is meant to help with Grocery Shopping, for people who have unique dietary restrictions or preferences. I made it because we were reading too many food labels when Grocery Shopping. If you are shopping for a family, the list of dietary restrictions can get long. The way it works is 1. You enter your dietary restrictions or preferences in natural language. This can be quite flexible. Examples: - I am allergic to oats and peanuts. - I want to avoid seed oils. - Dr Berg on YouTube said avoid…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  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…
