This logcat reader is the best out of the 3 I've tried. I read the last 10 one star reviews and they didn't disappoint! I'd give these people one star except they know how to breathe so they deserve two.

Until now I'd been using aLogcat, sticking with it because I paid for it years ago. I'm glad I switched, I feel like I've upgraded from MS-DOS to OS X. This app makes capturing, filtering and interpreting logcat output as easy as I could imagine, and the floating viewer is inspired and very well implemented. And thanks for not making me type pm grant commands or install Titanium Backup just to make the app work. I'll be recommending it.

The per-app logging feature is a lifesaver. I found out specifically why some of my system apps were force closing. Apparently, I disabled something important in Titanium Backup. Great UI. Smooth and comprehensive logging.

After deleting 55 system apps android settings would force close, I used logcat extreme, to find out what was causing settings to crash and it was the NFC.apk.

Most system/power-user focused apps are often lacking a good-looking UI, which isn't the case here.

Neat interface, floating window with necessary controls, logs manageable from within the app... What more could possibly one ask for? A debugging must-have. Why is this not on top of logcat search results?

but it would be a lot better if we could enable merged logs like CatLog. So view Radio and System logs together.
