This one is free, joining is free. Gives UK and some Continent Notams, no go areas plus a Nav function used at home in my case for several years as user friendly.

In the air the well loved AWARE programme for your own pad is perfect, alarm signal when closing on forbidden air space, proper CAA Charts, where you are etc. If you want all the Nav bells etc. you can link p.c. in planning to the airborne pad to show route and so on.
France and other charts are also covered for the cost of the electronic chart from AIRBOX.
I've used mine since inception and it's compatible with the paper chart you also carry (?).
