A few wine apps

I've decided to give three wine apps a go over the next month or so.  The first is Vivino which looks pretty clever and useable at first glance.  A sort of cross between Facebook, Strava and Wine-Searcher on first impressions  The second is Winosphere which is an Australian app, and looks to be a cross between Winefront, Twitter and Wine-Searcher.  The third is CellarTracker which seems more cellar inventory and US focussed.  I suspect it unlikely I will feel a desire to inventory my cellar anytime soon and start logging "ins" and "outs" which seems rather distinctly unfun.  But an inner accountant may emerge yet.
