Smart Rings

Replace the sizing kit
with an instant fit recommendation.

For smart ring brands, sizing kits add unnecessary delay between purchase intent and product use. Customers have to wait for the kit, measure their size, and then come back to complete the order. That extra step can reduce conversion, delay subscription activation, and add logistics costs to every order.

The Challenge

Sizing kits add cost and delay.

Smart rings need a precise fit, but physical sizing kits make the customer journey slower and more expensive. Shoppers have to wait for the kit, try it, choose a size, and then return to complete the purchase. For brands, that means extra logistics costs, delayed conversion, and slower subscription activation. For shoppers, it adds friction at the exact moment they are ready to buy.

Extra cost

Physical sizing kits add direct cost to every order.

Slower activation

Customers must wait before they can buy.

Friction

The buying journey becomes slower and heavier.

How It Works

From one photo to the right ring size

Aitaca helps shoppers find their ring size directly from the product page. The customer follows a guided photo flow and receives a product-specific size recommendation.

Computer vision sizing

Get recommendation
