Update to review below: Offline access and download speed problems fixed after they directed me to delete and reinstall the app. But marking-up in the app (highlighting, scribbling notes and answers on review questions) still causes the app to crash incessantly. Lots of IREX content is out of date, particularly since Part 91 came in, but even before that it still mostly reads pre-GNSS days re ground-based navaids vs RNP/GNSS/RNAV. ….. Original review: Content is excellent as ATC have been doing for decades, my first books over 20 years ago were invaluable to learn and understand all theory. This app needs to be thrown in the bin though. Downloading books for offline use took many attempts, seems you maybe have to leave the app running on the screen for it to download, and the speed is stupidly slow for some reason, I’m guessing because ATC’s servers are archaic? Then using them offline… certainly doesn’t work as smoothly as something should if it’s on my iPad. Sometimes sits there with a blurry screen like it’s trying to download. And it regularly crashes particularly when marking up with apple pen. Try harder ATC, this app really is a let down on your outstanding reputation.
