Technically it could use some more advanced regex/filtering on the OCR output, you're right! I found that with some receipts, you actually can omit cropping with some exceptions. I'd definitely like to remove the need for cropping altogether.

That's a great idea!

You nailed all the limitations of this app (and others like it) on the head :) The reality is that there will probably never be a foolproof way to understand our consumption/nutrition habits 100%, so my goal with this was to make it easier to understand at a high level what was in my groceries (that didn't require individual scans of each product).

I'm sure most chains have the purchase tracking for ads/marketing, but not sure how their data incorporates nutritional/ingredient data (if at all).

I agree. Hopefully there will be a day where grocery retailers provide access to their product data APIs to make this a smoother process. Or if the store provided a QR code on the receipt so you could quickly see information similar to what's on GroceryTrip.

Do you need support with this design? Happy to help out!

F91w is the best value watch on the market.

I prefer the F-105W. It's almost the same but it replaces the mediocre led backlight with a beautiful EL backlight. Fixes the only drawback of the 91 and hardly costs any extra.

FYI On Firefox Mobile, the slider touch area seems small, it's pretty difficult to get a gesture recognized.

You could use revanced!
