AirRadar is a simple and unsophisticated app which tells you just a little bit more than what you'll get from the built-in apple software. It has nowhere near the power of apps such as Kismac and APGrapher (which I recommend), both of which are both free.

The developer has added a fee to this product but not provided a single new feature. Even worse, installing overwrites the previous version, then asks you to pay for it after the fact, so I can't review this release at all because there is no trial period. And I can't revert to the previous release because it's been overwritten.

Ultimately, I don't care. There are way better programs out there that don't cost a dime. But my one-star review (and many others I'm sure) will send this program to the bottom of the Versiontracker junk pile.
