Seriously good!
There's no real reason to keep re-inventing the wheel and there's no real reason to second guess what people are clicking on. You get a good spy tool and you let it do the searching for you. Job done.
I like clean design, I expect fast and accurate results and will accept nothing less than professional support. Anstrex ticks all my boxes.
If you're looking for a well thought-out and well put together spy software, Anstrex deserves to be on you short-list.
It found a native ad I'd designed and written the copy for. The people I did it for originally said they weren't going to use it (to stiff me out of my cut). Boy where they surprised when I sent them the links!
Bottom line: Try Anstrex. It does what you need it to do and more!
