I would always support a "open source" project like pocketfms (not least because the whole business of map and aeronautical data copyright is so obscenely tight in Europe that anybody having a go needs support) so I am probably unfair to pocketfms in my comments.
However, I personally need a uniform database for Europe, not just the UK. The UK is a piece of cake - just buy the CAA chart for £14 or so, or for £50 for Memory Map, and fly around. It is when venturing into Europe that one needs uniform and reliable coverage. I don't think pocketfms will ever achieve this properly simply because GA activity in much of Europe is almost nonexistent.
I also need IFR (airways) flight planning and that is something else. Flitestar IFR is perhaps the only suitable product on the market, although one can get by with Navbox (to generate a plausible plog) if one does all the dirty work on bits of paper outside of it. It's a shame that Navbox has not gone just that bit further - the Jepp software is packed with perhaps too many features for most private pilots.
