I wonder what European flight planning apps people are running on smartphones.
Navbox, Skydemon and Flitestar are windoze only. There is no sign whatever of any of these being ported to Apple or Android.
There is nothing else for Europe that I know of - unless you are happy with a US app which contains some Euro waypoints and you can knock up a wind corrected plog with it. Years ago I used Copilot (on a PDA) like that; it was OK but there were no maps and if flying with GPS it didn't really offer anything useful.
I have an Iphone 4 here (not mine) and it makes a perfectly usable - for the screen size, anyway - web browser, so one can do the usual weather / notam / FP filing stuff on it because all of that is nowadays just websites. As indeed one can do with any other smartphone with a decent size screen. The fancy finger gestures are not necessary; I was doing all this just the same with a 4" Pocket/PC PDA with a stylus, 6 years ago (except one could not file flight plans over the www back then).
In that usage mode, a smartphone "can" do "all" a travelling pilot needs.
Personally though I find a 4" device a hassle. The browser font on the Iphone can't be changed in size (which is stupid, though I can understand the marketing reasons for that) and I need reading glasses to read it, whereas a lightweight laptop running winXP works a lot better for me, and runs absolutely everything straight out of the box.
Whether a smartphone can do everything else you need outside flying depends on your lifestyle. For me, the Iphone is packed with irritation. It cannot print (except in an extremely narrow context) and cannot even print to a PDF, which I do all the time. The only way to get stuff "out of it" is to email it to somebody, which is a hassle if you like to fly with the primary data printed out. Most hotels will print stuff for you but you have to get it out of the "thing" somehow
