What merchants say

★★★★★1 month ago

Exchanges dropped a fifth in one quarter. The fit finder paid for itself in reduced return shipping alone.

Bondi Brew Co · Sydney, Australia
★★★★★2 months ago

Per-collection charts meant we did not have to force one size logic across very different garment types.

Kalaa Studio · Jaipur, India
★★★★★3 months ago

Return-reason insights showed us exactly which style ran small — we fixed the copy, not just the chart.

Questions, answered

Can I show both cm and inches?

Yes — the toggle defaults by shopper market (cm for India, inches for the US) and shoppers can switch manually.

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.
