This is the most valuable app I’ve purchased for my flight sims. I wanted it for my iPad but didn’t read the description fully before I purchased on my phone. There is an iPad version called igmapsHD. After seeing how good it is I went and bought HD for my iPad also. It’s fantastic for seeing exactly where I am in the world. I can fly over the map and follow roads to known landmarks and find them in sim with ease. The weather filters are great for seeing what’s ahead, I can track ground speed and altitude at a glance and there are many other great features. Flying is simply not as enjoyable without this app and I wonder how I ever got by without it. Totally worth it!
