I've been using this for years, and just realized I haven't taken the time to praise it publicly yet. It stays out of the way until I need it, but is immediately ready when I hit the hotkey for it. I use it several times a day without even thinking about it -- perfect productivity enhancement for OS X! Still can't believe it's free.

Crazy good support from the developer! Open to suggestions and quick to act. Thanks!

Fast, powerful, stable and, um... fast. Just got this in a bundle at a good price, and loving it so far. Finally, a good audio editor that doesn't crash as often as many others out there.

Giving credit where it's due. With version 2.0 of AppStar, the author has addressed (and addressed well) my only criticism of the app's past version: At its new price, AppStar is a fantastic tool for any serious App store developer.

I have yet to dig into the other new features, but I've already purchased the app at its new price, and look forward to using it daily. It truly is a beautiful piece of software. Thanks!

I've been using Charles daily for more than a year now, and just realized that I've never reviewed it here. So to correct this omission: If you make your living creating Web applications, you REALLY should be using Charles. It takes all guesswork out of the interaction between server and browser -- simple GET/POST requests, SSL transactions, Ajax, XML, Rest, SOAP, Flash (even AMF calls), anything -- and shows you exactly what is transpiring when your users interact with your site or service.

The best part: It works regardless of which browser you use (in fact, depending on your network settings for a virtual machine, you can even debug using IE in a VM window).

You start taking the view for granted, and eventually you'll find you can also edit requests, optimizing your applications to ensure you only get/send the data you need.

Firebug, which I used extensively before trying Charles, will soon seem "quaint" -- and woefully underpowered.
