Excelente aplicación, literalmente un antes y un después. El asistente de tallas es súper preciso y realmente entiende las necesidades del cliente. Nos ha ayudado a reducir errores, mejorar la experiencia de compra y aumentar la confianza en cada pedido. La app cumple lo que promete: es intuitiva, rápida y se adapta perfectamente a nuestro tipo de producto. Se nota que está pensada para comercia...

The app is easy to use and understand, basically plug and play, no complicated install steps, and the customer service is very friendly; they also take your suggestions very much into account. Great app so far.

— El Akabeko

The app is exactly what we're looking for to reduce the exchange rate with our products. We sell tshirts and usually people just don't look at size charts anymore, they shop by instinct and its easier for most folk to just answer a few questions. We've seen the app works very accurately with its predictions and we can't wait to see the new improvements in the works.

I’ve had a great experience with SmartSize so far - the app works really well and is easy to use. The support team is super helpful and friendly, and I really appreciate that there’s a free plan available to get started - very fair and generous! Highly recommended!

— Jesus saves, Bro

I'm glad I can be one of the first to review this app, it's exactly what I was hoping for, easy to use, light on the page, support is 1000/10 and it allows for thorough customization. I highly recommend this app and whatever app these guys make, you know it's going to be solid!
