About Frequency Analyzer
The app calculates the fundamental frequency of a sound with very high precision. The error in the frequency is less than 0.04%
The app plots the fundamental frequency versus time.
The application can be used to tune musicals instruments.
The app can be used to measure sound Doppler Effect: J.A Gómez-Tejedor, J.C Castro-Palacio y J. A. Monsoriu.

I'm a bit confused about this app because i'm 13, boy and if i can create a 4000hz frequency, im not sure this app works :/

Tested accurate to within 0.1 Hz between 80Hz and 4kHz. Will be handy for checking my timing belt tension (needs 85-91Hz) :)

App does freq over time which is what I wanted but it provides no settings to control the sample interval. I needed a tighter sampling and smoothing would also be nice. Close but no cigar.

4khz voice, seems legit. Got a few years to go mate. works great with my signal generator to test response of speakers though

Shows 2.69 Hz as frequency when using my voice. Clearly not right. Also no graph is shown after stopping the recording.

Useful for identifying the exact frequency of a pure tone. I only awarded "2 stars" because: Contrary to developer's claim, app does NOT actually identify the "fundamental" tone within a sound that has harmonics ("fundamental" is the lowest freq in a series of harmonics and is normally associated with "pitch"). Instead, app merely identifies "peak frequency". App often reads an octave higher for human voice singing/holding a single note. Seems accurate for sustained pure tones, but does not work well for transient sounds like drums. Also, graph is not working on Samsung Galaxy Core Prime, Android 5.1.1.
