Freq.

Audio Frequency Analyzer

Only for iPhone

$0.99 · Designed for iPhone

iPhone

See what frequency any sound is. Shows the musical note and whether you're in tune. Freq shows you the frequency of sounds around you. Point your mic at something and see the frequency. If it's a musical note, you'll see which one and how sharp or flat it is. There's a spectrum view to see all the frequencies at once, and a waveform that shows the actual sound. You can adjust how precise the analysis is - faster updates or more accuracy.
