This is a joke. I think it was designed by a 3rd grader. No features at all. I didn't read the reviews before I bought it and sure wish I would have. I never leave reviews but this time it's a must if that tells you anything.

It does work as a frequency meter but is somewhat limited. It doesn’t work on frequencies below 150 HZ . I tested it on 150HZ then 120 HZ. It showed a harmonic of 120 HZ. 99 cents would have been a fair price. Especially since it appropriated the fluke meter style to elicit confidence and imply compared results.

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.

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.

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