Does anyone know if the elements are really native elements? Ie, they aren't some rendered html junk? I may have to try this out, depending on how simple it is

Does anyone know if the elements are really native elements? Ie, they aren't some rendered html junk? I may have to try this out, depending on how simple it is. I don't think it would fit for us at work, but if it's simple then it may fit nicely for my home projects. I've got lots of things i want to interact with via a phone app. If this means i can get a fast iteration cycle on little one-off (turn the lights on style) phone apps, then awesome!
