With Supersonic, we're doing something no-one else has done. We're combining great CSS defaults (from the Ionic Framework) with the best native APIs (from PhoneGap) – and adding a boatload of our own features on top.
For example, Supersonic has declarative native UI and navigation and powerful data integrations, something other UI frameworks don't provide at all. It also leverages Steroids Tooling to the full extent, giving you the best toolset for building hybrid apps.
This all makes Supersonic hard to compare to other platforms – no-one else is doing quite the same thing. That said, you can see below how Supersonic compares to vanilla Ionic Framework.
