Good app
Good app, would be perfect if it could plot a graph.
Works perfectly
I used my phone’s microphone and this app seems to measure frequencies very accurately. I used it to EQ my desktop speakers.

Pawlish this program is very interesting despite its ease you use.
Horizontal orientation...
... Only one layout. Can’t flip it over. 😒
Great app and with a larger frequency range
This app does all you could want if you are interested in seeing what sounds are around you. This app will measure up to 40 khz and as most only measure up to 16 khz and it is free. Easy to use and save snapshots to your photos( iPhone).
Very impressive
This app is really easy to use and I find it very impressive!
Poor
Needs better programming. Needs averaging and slow response

This app works awesome. Only one upgrade I would suggest would be the ability to take screen shots and a record feature for data. I would still highly recommend.
Matches our calibrated microphones.
I work in a Modal lab. I downloaded this app just for quick measurements on the fly, to verify my test setups. Works great. The FFT matches our $90,000 analyzes and calibrated microphones. I am impressed to say the least. Please update allowing for triggers.
