Our mobile web app developers use leading HTML5 development technologies and JavaScript-based frameworks, such as SproutCore and Sencha, to take advantage of various device features and capabilities. Our JavaScript based mobile web app development services are: 1. Using HTML5 and CSS3: Accessible by most mobile devices and supported by all the major browsers, HTML5 and CSS3 are able to take advantage of new features and capabilities, thus providing a better user experience. 2. Optimized for today’s touchscreen devices: No more mouse clicks and cursor pointers, our mobile web app developers use frameworks, like Sencha and SproutCore, to build UI elements and event-handling specifically tailored to mobile platforms. 3. Cross-platform: Build the mobile web app once and deploy it across multiple platforms such as iOS and Android and start reaching a much broader range of users. 4. Lightweight: Lowering file weight is very important because of current bandwidth limitations.
