Two strikes kept me from looking at this:

1. You posted this as a direct link and don't even have a comment with more information.

2. Registration required.

I was interested but as you note registration is required and one doesn't even get an explanation or a screenshot without signing up.

Also, supermarkets move all their stuff around every few months in order purposefully to disorientate shoppers. I'm surprised that any want to sign up and would be inclined to think that the data is likely to be wrong quite a lot.

We update AisleFinder on a 4 Month Cycle by verifying product/aisle info. We have done analysis/focus tests to find that we have a 97 % accuracy in our info as well. The only reason for that 3% is items like Honey (which can live in many different places in a store) unlike some people we dont speak before we know something for sure.Thanks for your feedback though. I will let HN know when those numbers change.

thanks, the only reason we capture this data is to keep track of your shopping lists. I will take into consideration though.
