Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCart Reserve holds available inventory when a shopper adds a protected product to cart. Each reservation is tied to a signed session and verified again at checkout. The storefront timer reflects the active hold, and expired reservations return to stock automatically. Use Cart Reserve for limited stock, one-of-one products, restocks, flash sales, and product drops.
Shoppers add a one-of-a-kind item to their cart, race to checkout, and find it already sold. HoldCart places a genuine inventory hold the moment an item is added, so the unit is actually reserved while they check out, then auto-releases back to stock when the timer ends. It is not a fake countdown or manufactured urgency — it is a real hold with a real timer.
- Real-Time Reservation: Lock inventory instantly when shoppers add items to cart.
- AI Fraud Detection: Identify and block bots to protect stock from abuse.
- Auto-Release: Expired reservations release stock, keeping inventory accurate
- Per-Product Rules: Customize reservation duration & logic for specific products.
- Real inventory holds — items are genuinely reserved at add-to-cart, not faked
- Fail-safe by design — if the app fails, your checkout keeps working
- Honest countdown — shoppers see a real timer backed by a real hold
- Automatic release — holds expire and return to stock on their own
