It may sound hard, but it is pretty useless, as the iPhone already does that by default …

I don’t see any further interest in that app …

The default UI also doesn’t tell you if the “open” network is actually usable – many open networks either redirect to a login page or do MAC address filtering. This application will tell you if it’s a useful open network or not.

Additionally, for the network admins among you, there’s a details page where you can drill down to see MAC address and as many other details about the access point as I could request from Apple’s APIs (I’m the author).

i got this App. on the day it hit the App. Store. i like it, and is one of my most used Apps. here in Louisiana, we do not have 3G. so i check, where ever i go for an open wifi, and it works great. it took La. ” ten years ” to totally convert, from TDMA (analog) to GSM (digital), so that’s not an option for me. i too have one of those Keychain wifi finders from Kensington, it’s nice has five LED’s for signal strength, and also has a Bluetooth LED, and a mini LED Flashlight, but this App. finds more locations, and offers much more, like: Router Name, WPA, WEP, Open, Locked, and Hidden.

Just used the app to get online at Sacramento airport. Helped out a lot when i fired up the old macbook there was only one wifi connection shown. so i fired up WiFinder and found out there were six and one had a signal strength of 31 when all the rest were at like 12. without WiFinder i would be sitting here with a slow connection like everyone else.

has channged its name: new name = WiFi Checker
