Nick, thanks for a great article! I have been using Google Analytics for so many years (btw still using) and noticed some of the points you mentioned. Those issues are relevant not just for web analytics, but also for mobile analytics. And this is exactly why we decided to create Inapptics — http://inapptics.com/.
Thanks for sharing! It’s very detailed and well explained :)
I’ll suggest also checking http://inapptics.com/. It’s an analytics platform that helps mobile app creators visually analyze actual user behavior and improve their apps with proactive insights.
