What merchants say

★★★★★1 month ago

70% of our traffic is mobile — this was overdue. Checkout starts moved within the first week.

Northfield Co · Austin, USA
★★★★★6 weeks ago

The free-shipping progress meter in the drawer quietly lifted our average order size too.

Kalaa Studio · Jaipur, India

Express checkout buttons in the sticky bar cut two taps out of our mobile purchase flow.

Questions, answered

Does the sticky bar work with our existing theme cart drawer?

Yes — it can either extend your theme's native drawer or run its own slide-out drawer, your choice in settings.

Will this slow my storefront down?

No. Every widget renders as a theme app block with no render-blocking JavaScript — median added weight is under 6KB of HTML.

Do I have to edit theme code to install it?

No. Drop the app block into your Online Store 2.0 theme editor. Nothing is left behind if you uninstall.

Can you migrate my existing app's data?

Yes. Send an export or grant access and our team migrates it free, usually within one business day.

Which plan do I need for a large catalogue?

Growth covers most stores. Above 10,000 products, Scale removes the cap and adds multi-store management.
