Like parts of the app

The app works pretty well at detecting WiFi and I love it for that. It would be nice to have some location features on a map of sorts, so you could get an idea of WHERE you were (seeing how it *DOES* seem to integrate location) when you saw an item. Actually, I thought I remember the app having a feature like that, but I’ve used a couple of these now. The other thing that makes it not quite as useful is that you can see the “delay”, but you only have one customer server to set as well as only a handful of provided servers, and since you can only see ONE delay at a time, you can’t compare servers quickly to be sure if its your network or your server thats causing a slow reading. Finally, if I get a really AWESOME reading and decide I want to make my friends jealous, they have to be using Twitter. I don’t use Twitter — at all. Which makes sharing the data more difficult. And I’d really just prefer a simple quick “screen shot” style capture anyway so I can archive the info for myself and, if I really want to share it (I really don’t, but if you are supporting Twitter… might as well support the other popular outlets), I can share the image without having to bother with my own “Appshot”...

Works Really Well

I used this to help trouble shoot WiFi at home. It’s amazing how many WiFi spots you an see in your neighborhood. I used this to help move my WiFi channels away from my neighbors to minimize interference and improve signal quality. Definitely worth it, an essential tool to have. I would love to have a copy on my iPad of mobile troubleshooting.

I absolutely love this app!!!

It gives me useful wireless data about my networks and those in the area. This is a great down and dirty, get to the point, simple wifi diagnostic tool.
