Would you care to share how does this app work under the hood? I think the hacker news audience would be more interested to understand that then to use the app per se haha. Do you parse the page for a bulleted list next to certain keywords?
Also why not just make this a browser extension instead of an app to remove the step requiring the user to scan a QR code?
So schema.org has a standard json schema for recipes. Crawlers use this information to parse and figure out what kind of content lives on the page.
Since google encourages this and ranks pages with schema higher, all recipe blogs and sites add this schema to their html.
This is structured data. I just parse this json.
Not all recipes follow this though. So you may occasionally see error messages for old sites that have not implemented schema.org structure.
Regarding your second question, I built this as a side project to learn flutter. I learned the basics of flutter and wanted to build something with the newly-acquired skill.
Hence the mobile apps and web app. All these are built with flutter. :)
Let me see if I can integrate this inside a browser extension.
ohh interesting, I didn't know about schema.org -- that's pretty cool!
No worries about making it a browser extension. I wasn't sure if you're trying to make this into a business or not. I would envision this working similarly to iOS's reader mode but for recipes. Best of luck!
