These days with so many apps to track, this is a must-have. Yes, there is other software that tries to accomplish the same task, but I've tried many of them and LicenseKeeper is the best of the bunch. It's not a Swiss Army knife type of app. It's dedicated to the sole purpose of tracking your software.

I really like how easy it is to update entries. And adding documents and emails about an app is really easy and useful. No more hunting through old email trying to find that receipt with the serial number. The number and the receipt is easy to find in LicenseKeeper.

I also like the feature that tracks when a program was purchased, and how much was paid. I also use the notes feature for such things as recording the names of the users of a multi-user license, or what an app does, or my personal rating of an app that I own, or where I acquired the app.

The developer is responsive, too. I've sent suggestions and received a personal reply. He also keeps the app updated frequently.

This app is on my A list along with SuperDuper! and 1Password and Dropbox!
