"I thought about OCRing supermarket receipts too but these differ so greatly in layout etc. per country I figured it's not the way to go"

People usually shop at the same places and the same things, so they could identify the products in the receipts once and then only update the new ones. Also,You could crowdsource it.

Yep but I was looking for a turnkey solution. What you describe are workarounds. I tried several grocery management apps, and a lot of these did just that: Prompt me for data when a barcode did not result in a matched product. This is not the experience I personally tolerate and am looking for. For an app to get integrated in my grocery shopping, product identification needs to work seamlessly and reliably
