I'm a recent convert from Garmin and Basecamp, MRA is the best Nav/Planning app I have used. took me 2 weeks of use to decide to upgrade to the Gold/Next options.
If you have a Android based phone, you have to wait a little longer. The release was 23 september and the last time update for android came about a fourth-night later. So in this case it will be about the second week in October I hope!
