LOL. There are a lot of apps that are used only occasionally, and a lot of apps that are used on a daily basis. I use Torque Pro only right before a smog check (to ensure that the sensors have completed their readiness tests), or if the "Check Engine" light comes on; I could go more than a year between launches of that app. WiFi analyzer falls into that category as well. An extremely useful, but only occasionally needed, application. It's odd why it's not possible to have such an app on iOS anymore.
But I'm sure that nospam will appreciate your attempt to become an ordinary, regular, typical, normal, person instead of some freak that uses apps with only 10 million, versus 100 million installs.
