“Baaqi’s customer support is truly outstanding and highly professional. Thanks to his thoughtful and responsive support, I’m able to fully leverage this excellent app in our store.”
“Terrible and untimely support. Do not recommend this app given the headaches it's caused. They are seemingly unable to unanchor their own button to the built in our of stock button on our theme. They also installed a new feature on our store without our permission and I had to request it be removed urgently.”

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 Jun 12, 2026.
