Ive had this app for nearly a year, but hardly ever used it on the iPhone, the screen was simply too small for my taste. I was thrilled when they ported the app to the iPad, and although 10$ is a steep price for an iPhone app, the iPad version is worth every penny. However, I purchased GP6 and was disapointed to realize this app doesnt support gpx, the file format of gp6. Lets hope it comes in a future update. On an asthetic point of view, its clean and simple, but some background customization could be a plus. If youre thinking of buying and have GP5 or prior charts, dont hesitate. If you have GP6 and plan to fill the app with those charts, wait for an update before purchasing it. For some reason, GP6 dont allow to save under GP5 format.
