I use this app nearly every day. It finally brings ACOG into the 20th Century, if not the 21st. I can't tell you how frustrated I get with the website, but this app is very workable and has been since the launch. There is definitely room for improvement in the experience of viewing the tables, graphs, etc. Scrolling can be touchy too. Work out the minor kinks, link to ABOG/MOC, and let me check my CME here, and you'll get 5 stars, and I'll never go to the website again.
