FAQ

PopUp — frequently asked questions.

What is PopUp on Shopify?
PopUp, officially listed on the Shopify App Store as PopUp ‑ Sell by Weight, is a Shopify app in the Selling in person - Other category. Shopify POS can't sell by weight. So like most market vendors, I ran two systems — Square for in-person, Shopify for everything else. Two catalogs, two logins, manual reconciliation every tax quarter. I built PopUp because I needed it. PopUp adds weight-based selling to Shopify POS. Mix weight and flat-price items in the same cart. On-device catalog, no Shopify inventory needed, works offline. Pause between seasons, no data lost.
How much does PopUp cost?
PopUp offers a free plan and 2 paid plans starting at $4/month and going up to $30/month. The free plan includes Up to 5 products and No credit card required - never expires. The paid plans unlock advanced features beyond what's available on the free tier.
Is PopUp free?
Yes — PopUp offers a free plan alongside paid options. The free plan includes Up to 5 products and No credit card required - never expires. Paid plans start at $4/month for advanced features.
When was PopUp launched?

Is PopUp Built for Shopify?
PopUp does not currently carry Shopify's Built for Shopify badge. The badge is awarded to apps that meet Shopify's published standards for performance, ease of use, and merchant value — many high-quality apps operate without it.

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 .
