I tried my 6s with Skydemon (I already have it on an Android tablet). Apart from the size of the display it works better than on the tablet. A little greedy on the battery so I often use it to check on 'other stuff' Notams, other plates whatever, which the Android table cannot do (no data connection). As a sole source I suspect it would be a little annoying due to its size - but it can certainly do it all, but I suspect you will need additional power either a USB charger or power pack or short flights!.
