Best Wifi App you will Find

This prorgam extremely helpful when setting up wifi. You can monitor where the best placement of hardware is to be situated.
Also its great when you travel so you can see which wifi signal is best. It would be very helpful to have an iPhone and iPad version as it would be more portable. Also great for surveying pay as you go hotspots. You can monitor their signal strength before you sign up.
