Any app in particular you would recommend for Android users? Looks like we don't get Vibration.

No, you'll have to look around. It's important it can do FFT (fast fourier transforms) to get the frequency from the time/amplitude data

I encourage you to get one - it's as much fun on suspension as measuring aero pressures.

I found a couple that might work: vibration analysis pro ($1.99) and myFrequency ($9.49). myFrequency is a little pricey, but seems to be a lot more user-friendly than vibration analysis pro and has more tools for analysis in-app, including spectrum analysis. I downloaded both to try out.

myFrequency looks good. I hadn't seen an app before with any analysis of damping - that could be very interesting.
