As for Android: check out "DCS MANAGER" in the market. https://market.android.com/details?id=fr.yeepeekai.dcs.manager&feature=search_result#?t=W251bGwsMSwxLDEsImZyLnllZXBlZWthaS5kY3MubWFuYWdlciJd
It's not that sophisticated as the iBrother, I must admit, but it gives you the basic information you need when in flight, i.e. checklists, emergency procedures and airport data information with very nice and usable airport charts.
I'd like to see an Android version with fuel calculator (time, distance MTOW, MLW, WDC, calculated rotation speed etc) and NavAids. If there is an Android geek around pls give me a call, I am a real life pilot and could provide all the data necessary.
