Ionic is only to look and feel the UI interaction. Nowadays it requires Angularjs to work with full potential, but CSS is mostly used for the framework and we will miss the UI interaction, animation and many things. We have to explore beyond Angular to support other framework.
Ionic is an open source framework. Its use for commercial or personal project is for free. It is focused on building native app rather than mobile websites. For the kick-start we have to just put prebuilt template for our app design. Just putIonic to your Cordova, Phonegap or trigger.io project and our app is ready.
Note :- We have a team of expertise who do all the work by their own, so we need no to offshore or outsource anything. Your work will be confidential as per our term & policy
