I knew there had to be a better way to build mobile apps

The time has never been better to learn mobile application development. For many app ideas, you don’t even need any prior native development knowledge. You can get started today with knowledge of HTML, CSS and JavaScript. Unlike native mobile development, mobile applications using web technologies can support many mobile platforms. I shared my own experience on building hybrid applications based on PhoneGap also explained why I suddenly changed my own opinion about native apps and switched back to Xamarin.
