I use foreflight both in the UK and the USA.
Fantastic product for flying both VFR and IFR in the USA.
However, in the UK, although foreflight has upped their game in Europe, for just VFR flying, I think there are better products available, such as sky demon and the like.
For both VFR and IFR flying in the UK then Foreflight becomes a worthy contender especially with the geo-referenced IAPs and if you have a Garmin navigator such as the GTN 750 or 650 fitted with the flight stream 510 or 210 option fitted as well then it's a huge thumbs up from me.
