What merchants praise

The app works exactly as stated and was a breeze to install. Because of my Shopify theme, we needed to do some customization and they were more than happy to help us. We greatly appreciated them going above and beyond. Now we are up and running with ease and have peace of mind knowing our terms and conditions are being agreed to by our customers.

What merchants complain about

I purchased this for the ability to use a keyword to determine if the box showed at checkout. People are somehow able to bypass the check box without ticking it which is causing problems for my business. I’m paying for this app, I contacted support and received no response. If people can get around the box it’s a waste of time having it.

    Methodology

    Where the numbers come from.

    Ratings, review counts, pricing tiers, “Built for Shopify”, launch date, and category memberships come from the live Shopify App Store listing — refreshed daily by Ongoing.AI’s crawler. The review-count trajectory is the diff between today’s snapshot and snapshots from 7 and 28 days ago. Topic counts and sentiment come from the review corpus, topic-tagged with Claude. Install footprint is observed via Ongoing.AI’s tech-detection pass against actively-tracked Shopify storefronts. Catalog position is computed at snapshot time against every active app sharing the primary category. Snapshot generated .
