Floyd is a new engine to Android but don't think it's the first attempt of a candidate chief cooker.
Marcel van Kervinck is highly experienced in programming, not only chess but other stuff too. Those who remember MSCP and Rookie, two older engines from the same author, should have already heard about Marcel.
Floyd 0.6 is still experimental, probably under 2000 ELO on Android. We'll see about that soon when it gets ranked in Rapidroid.
