Yes! You can access Salesfloor on any desktop computer or mobile browser by simply logging into your account at your retailer's URL with "/app" at the end of the URL.
e.g. subdomain.domain.com/app
For example, if my retailer's site is shoptillyoudrop.com, and my storefront is mystore.shoptillyoudrop.com/sophie, I can access all of the great features of my Salesfloor app, by logging into mystore.shoptillyoudrop.com/app
Once logged in, you'll have access to all of the features you love in the palms of your hands, only now in a browser window!
