It's CatLog, but with material goodness.

Graphical log reader for Android. Based on Daniel Ciao's Matlog Google Play, Github
which is based on Nolan Lawson's CatLog: Google Play, GitHub

Overview

Laughing Logger is a free and open-source material-style log reader for Android based on CatLog.

It shows a scrolling (tailed) view of the Android "logcat" system log, hence the goofy name.
It also allows you to record logs in real time, send logs via email, and filter using a variety of criteria.

FAQs

Taken from CatLog's FAQ:

Why I can't save logs or start recording ?

The applications might be missing "Storage" permission if you are on an older Android version (Android 10 or less) and/or READ_LOGS permission has not been granted.

Where are the logs saved?

On the internal storage, under /internal storage/Laughing Logger/saved_logs/ if <= A10,
under /internal storage/Android/media/org.laughing.logger/Laughing Logger/saved_logs/ if >= A11.

How to I access saved logs ?

A simple "file manager" application you can us is Files by Google.

I can't see any logs!

This problem typically shows up on custom ROMs. First off, try an alternative logging app, to verify that the problem is with your ROM and not MatLog.

Next, see if your ROM offers system-wide settings to disable logging. Be sure to reboot after you change anything.

If that still doesn't work, you can contact the creator of your ROM to file a bug/RFE.
