I love AHD
But I dislike that you have to pay $24.99 for every edition that comes out. I had 4th edition but couldnt use it with new iOS versions. So, I went ahead and purchased the 5th edition to continue using the app. Ive been restricted many times for weeks or months at a time from using the app when they update or do "bug fixes". I usually end up using Google to find definitions. Anyway, when it works, its excellent! Unfortunately I dont think Ill purchase 6th edition if they cant manage the 5th.
