App Introduction
Eliminate customers' size concerns that hurt your sales and returns RingSizer helps your customers find their perfect ring size. Size uncertainty is one of the top causes of cart abandonment and returns for jewelers. Our app adds a "Find My Size" button to your product detail pages, letting your customers easily measure their finger or an existing ring directly from their phone. Co-developed with jewelers, we use machine learning for accurate size predictions. Installs easily with no developer needed; it seamlessly integrates with your store’s theme and brand.
