Do you know of a review app that can provide both general store reviews and product specific reviews?
The store I'm currently working on sells two types of products 1)One-off vintage items 2)replenishable items and ideally I'm looking for an app that could provide non-product specific reviews on the one-off items (similar to how Etsy shows reviews of the store and not specific to the product), and then product specific reviews on the replenishable products?
I mentioned this one in my original reply here. The Judge.me app does both product and site reviews from their description.
