Hey there 
In the latest app we’ve developed, Ionic was the framework we choose … and it was the best choice ever! Also, we choose Parse as the backend but unfortunately it doesn’t play nice with AngularJS/Ionic.
I started a simple library that makes the integration seamless and enabled data-binding that we’re love. Check it out here and let me know how can I improve it and it this is something you will benefit from.
Thanks,
Andrei
