You might want to consider renaming this project. The NS prefix is reserved by apple for framework classes. The entire purpose of prefixing classes in Cocoa is to prevent namespace collisions between different organizations, which using NS outside of apple breaks. It doesn't actually look like you are using the NS prefix in any of your code, so you're not technically violating the below rule, but I still think it worth considering. NS kindof means "from apple".

"Objective-C classes must be named uniquely not only within the code that you’re writing in a project, but also across any frameworks or bundles you might be including. As an example, you should avoid using generic class names like ViewController or TextParser because it’s possible a framework you include in your app may fail to follow conventions and create classes with the same names.

In order to keep class names unique, the convention is to use prefixes on all classes. You’ll have noticed that Cocoa and Cocoa Touch class names typically start either with NS or UI. Two-letter prefixes like these are reserved by Apple for use in framework classes...

Your own classes should use three letter prefixes. These might relate to a combination of your company name and your app name, or even a specific component within your app. As an example, if your company were called Whispering Oak, and you were developing a game called Zebra Surprise, you might choose WZS or WOZ as your class prefix."

In practice many people use two letter prefixes for their classes, you should use a prefix with your classes!

The project looks great, I've been wishing for a more comprehensive logging system with filtering built in for a while now. Thanks!
