Customer Reviews

  • Science Project

    by BPaulD

    My daughter and I used this frequency meter for a science project measuring the vibration frequency of guitar strings. At first it seemed that it didn't work at all (as mentioned in a previous review). However, I then realized that we were working in a frequency range that was very likely below the realistic frequency response of the internal iPad microphone (I'm guessing around 100 Hz). When we moved to a smaller string and at higher tensions, the frequency meter locked right in and gave very consistent and reliable results.

  • Ugh

    by #confused

    It worked really well, but I can't figure out how to send the data...

  • Technician

    by sound nerd

    Only identifies a very narrow band of frequencies - 1800Hz tops - not too much below it either. And doesn't correctly identify the frequencies within that narrow band consistently. The problems aren't with the iPhone's capabilities. Just d/l another one that consistently identified everything I threw at it from 43 Hz to 15000 Hz using just the internal iPhone microphone.

  • Don't waste your money

    Don't waste your money hard to use and no directions.

    Don't waste your time. Barely works, some buttons don't at all. Crashes frequently. Going for a refund now

  • Awful app

    by -Anonymous---

    This is awful. It doesn't work at all. Don't buy it.

  • Garbage

    by arthurheely

    Don't waste your money. I compared measurement to a quality frequency counter and this app isn't even close. The reading is erratic. Absolutely no documentation or help.

  • Frequency testing

    by hotforit

    Seems like an app that could be very useful but this first release needs some work. The oscilloscope function works nicely but every frequency I sample shows the same on the digital display 4538.48. I am also unable to figure out how to use the chart or export function.
