Hopefully I will be wrong about this, but I'm not expecting this to be very helpful. In dense areas of SF, where I live, open parking spaces last less than a minute - sometimes only a few seconds. If where you're parking isn't densely populated, then you don't need the app at all, because you can easily find a space.
