STICKY ADD TO CART

The buy button that never scrolls away.

A slim bar pinned to the edge of the screen: product, price, button. However deep they scroll into reviews and photos, buying stays one tap away.

Scrolling is interest. Don’t make it a detour.

The shopper who reads every review is your most convinced shopper. And on a long page, they’re also the furthest from the button. The bar closes that distance to zero.

Small bar, careful manners.

01 · THE TRIGGER
Appears when the button leaves.

The bar only shows once the real buy button scrolls off screen. No doubled buttons, no clutter above the fold.

“We've been using Vitals for our store at Bigksport and it replaced at least 6 separate apps. The product reviews, upsells, shipping estimates, sticky add to cart and visitor replays all work seamlessly together. The fact that it doesn't slow down your store while doing all of this is the biggest win.”
