The homepage look very nice but I had pretty much the same issues as you. ---

Frankly I built my own UI because I didn't like the opaque layer most mobile web framework are doing (exception being jQtouch but it's pretty old). It's not "that hard".

It's also bound to angular out of the box. While that's great for people using that framework, it's a big learning curve for anyone else.
