Didnt work for me. Looks nice but charts dont always load,when zooming in to view obstructions or placing way point it zoom all the way out instantly by itself every time. Frustrating. Wish it worked for me looks good and good price but charts froze half loaded. Reloaded app still no luck. App also blast you pop ups to rate with any click on the app before you get to try.
