I was waiting for MVE mobile app of cscart since long and after testing this on several mobiles now I'm doubtful to buy it as it crashes so frequently that thar sometimes it does even open again. You really need to test it thoroughly using emulaters and real mobile set of all configuration. Its Not at all tested well hence so much of performance issues been reported.
Cs-cart Multivendor support If you are looking for a app that support cs-cart Multivendor (marketplace) then use this . Really it's a great app with rich features.
