AppGyver has debuted a new mobile HTML5 app framework called Supersonic, and the company claims it provides hybrid app performance that is "indistinguishable from native."
According to AppGyver, "Supersonic introduces a new, declarative way for building high-performance mobile app user interfaces. By extending standard HTML5 syntax, Supersonic introduces a whole new set of native elements previously inaccessible to hybrid app developers. This seamless interplay of HTML5 and native UI blurs the line between the two, and reaches performance unseen in the hybrid app space until today."
Supersonic is available for free to mobile development pros who have an AppGyver account.
