Great

Great and accurate for all your needs. Identify a frequency in a second. Unique on the AppStore.

Does its job as expected

It is important to extensively test this tool in order to understand its functions. With this tool it is possible to filter out the different frequencies of each of the sources of sound in a room. It is possible to check the function of ultrasonic devises used to scare away rats or similar animals. The App can even be used to detect harmonics of sources of sound. Of course that you have to consider the capabilities of the used hardware. A modern iPhone 14 will produce more accurate results compared to a iPad Air II of more than 7 years old. Yes, you can use it to tune a music instrument. A great App!

No mide con fiabilidad la frecuencia

Not accurate frequency meter

Absolutely not accurate frequency meter. For example: for frequency 300Hz meter shows 283 or 312Hz. Nothing more between this two values. On other frequencies is the same. Its fake, its toy but not frequency meter.

Don’t know how it’s works

I read a lot of readings but don’t know what I read. There is no (short/simple) manual how to set to measure frequency or….

For now I can’t use it.
