Good - Could be Much Better
I do like this app but it could be much better. The fact that they give CFIs a free subscription cant be beat. Very smart on their behalf.
The user interface needs a makeover for 21st century human factors. The sectional is very cluttered at the default settings. Right out of the box many annoying features must be disabled to make the sectional user friendly for a pilot. It certainly seems it was designed for people who are not pilots or cannot read sectionals. For example, "Heading Ind," a gigantic annoying compass rose, VORs, state borders, etc, etc, all must be disabled in the settings before I use the app. All this data is right there on the sectional already and is just clutter overlaid by the app.
A note to the developers: please, please, please for the love of God make there a way to disable those annoying airport labels on the sectional. Also, as stated below, the ability to selectively download individual sectionals as well as terrain data for the synthetic vision (which cannot be used without an external AHRS, anyway) should be features added in the next update.
