I have it on my ipad mini, indeed it is the only reason I bought a mini. I have a remote Dual GPS which works a treat. SD is great and easy to use. Thoroughly recommended, all your wx, notams and flight logs in one place. Android version should be coming soon, weeks not months away.
Chart coverage includes most of Europe (I haven't checked exactly) but I have used it for planning to France and Germany but it covers way more than that.
