Modified App is a mobile phone application which seeks to consolidate the huge modified car parts market, both new and used. A once thriving trading community has transformed from the desktop Forum setting and has been diffused among a variety of mobile app based communities, none of which are fit for purpose. With PayPal payments built-in, coupled with full buyer and seller protection means user confidence is high. Picture based layout encourages swift browsing. This theme continues with the item listing process to promote quick uploads rather than the long, drawn out affair that other marketplace apps employ. Being enthusiasts ourselves, we are well positioned in the scene to monitor commerce trends and cherry pick desirable brands and products to help divert traffic to the app. Commercial users are welcomed, too. We understand shoppers' loyalty to certain companies, so what better way to keep a potential buyer interested in certain products seeing your products every day.
