QS for Neurological Movements /Tremors

Hi there,

I have been looking for a tool to measure my neurological movements, especially tremors. I have been noticing it in several occasions and varying strengths, but I am also aware that there can be different causes for it. In my opinion, a smartphone provides a better tracking tool than my occasional visual checkups by the doctor.

I have tested several tools, that mostly test the hand oscillation. It worked pretty well for the iPhone apps tested. Neither of the professional apps are for free though. I liked

Tremor Test (seems to be the most professional and accurate)
and Tremor-Meter (looks nice, but results cannot be compared)

So these QS tools can provide information about the current neurological state. What do you think about it?
