Comments on SimpleFFT for Android

★★★★☆ A Google User · Dec 26, 2012
Needs more Please add more features like gain controll. Lengthy waveforms
★★★★★ Jesse · Sep 28, 2011
Simple but good Practically no options but works well. Would be nice if there was a screen capture button and maybe a frequency/amplitude trigger.
★★☆☆☆ Eric Hedekar · Jan 20, 2012
Works but Not logarithmic and only goes to 4kHz. Better free FFT apps exist.
