AliExpress

Big marketplaces are notoriously difficult to handle, especially on smaller screens like the ones on mobile devices, so any application that aims to give users access to such a huge resource needs to provide all kinds of features and options.
 
Users don’t need to have an account if they are just window shopping, but it’s needed if they want to buy something. The application keeps track of your purchases and gives other suggestions, it’s possible to save only the stores and sellers that you’re interested in, and there is a very handy currency converter available.
 
It’s also possible to browse the categories just by images, sort the results, calculate the shipping rates bases on location, use various coupons, and even check out some of the recommendation from fashion bloggers.
