First off: the charger *itself* as hardware is superb. Beautiful and small. Installation went really well. But: the app is an absolute disaster. It beggars belief that a modern piece of hardware would have something with such awful UI, that has so many bugs and which is so poorly put together. The reviews on Apple tell the story, as does the fact you haven't had a single app release in *7 months*! Come on guys. If you want me to help, let me know. I could even get some designs done for you. If you're serious about taking on Zappi and others, you absolutely have to do better.
