Wifi Analyzer

Hi all, I have got wifi analyzer installed on my SGS2, a brilliant must have app on my phone. So when I saw it on Goodereader, I snapped at the chance to get it on my playbook.

Unfortunatley, it does nothing and can't find any other wifi signals, just a blackberry signal.

Does anyone else have this installed and working correctly? or is there another app outhere that can do the same thing?

I have it installed on my PB as well and it does the same thing. It always shows -38db and only shows the Blackberry Network. It does nothing else.
I thought I was alone, but it seems I'm not.

I carry around a rooted Nook Color in my truck for just that one exact app. I would be happy to pay for an app on the PlayBook!
