Has anyone tried using built.io as a backend for Ionic?

I like firebase and have been building my app around it - but there are just some issues that feel difficult to resolve with firebase. I need something real-time too. Just came across Built.io and wondered whether it’s worth exploring further.

Thanks

Built.io Backend’s JavaScript SDK is compatible with most frameworks available today. Ionic Framework uses Angular.JS framework. As a result, Built.io Backend works smoothly with Iconic. Besides, their documentation too is straightforward and easy to understand. Here’s the link to Built.io Backend’s Javascript API reference.
