FAQ:
Q: AGHHH! WHY DOESN'T LOGCAT WORK ON INTERNET EXPLORER?
A: ARRRRHHHH WHY ARE YOU USING INTERNET EXPLORER? IT DOES NOT SUPPORT WEBSOCKETS!!!!
Q: Hey bro, why does Loggy need root?
A: Well bra, it's because as of JellyBean, apps can only access their own logs, and not the system log or other app logs. So root is required to see the full log. https://plus.google.com/103583939320326217147/posts/2Yb5wgrx5ib
