Actually is hard to think in any new service without creating a mobile app, be a sales store, a social resource, any delivery service or even a game, all want to be present on mobiles.
Until some years ago, the ability to make a mobile app was just limited to those who knows C, C#, Java or yet other proprietary language, but than, comes the Adobe PhoneGap tools who give to all web developers the chance to build a native app using web coding knowledge.
The PhoneGap Service is free for building open-source apps through the github account, or in case of private projects the price depends of the plan. On free account the user can have at least one private project.
Basically, to get started, the developer just need to make or have an Adobe Id and subscribe to the PhoneGap Enviroment. After that the developer can download the desktop tools to build, compile and test the developed apps. Also, instead of download any software, it’s possible to code a native web app and upload a zip file to the PhoneGap Enviroment just to compile.
The online PhoneGap Compiler is fast, accepts to compile with your developer key and also gives a QRCode to download teh compiled app to test.
The PhoneGap compiler actually can build apps for Android, iOS and Windows Phone, which is very handy.
