I've released an Android version of my Audio Spectrum Analyzer app, which you can get from the Google Play store: https://play.google.com/store/apps/details?id=com.blackcatsystems.SpectrumPad



Audio Spectrum Analyzer turns your phone or tablet into an audio spectrum analyzer. Frequencies up to 20 kHz can be displayed, either with a linear or logarithmic frequency axis.

You can control the displayed frequency span, as well as the FFT size, from 1024 to 262144 bins. The larger the FFT size, the longer time between updates, but the higher the frequency resolution.

Logarithmic display is available, and the graph fill mode can be turned on and off.

Up to five frequency markers can also be displayed.

You can select from 8 different windows:
Rectangular
Hanning
Hamming
Tukey
Cosine
Lanczos
Blackman
Blackman Harris

The iPhone/iPad version is available on the iTunes App Store: http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=373620982&mt=8&at=11lb5X
