Ratings and Reviews
Only shows certain frequencies
2 problems that make me want my $2.99 back:
1) I can't analyze frequencies without recording a file.
2) The frequency meter actually just shows you which note (A/A#/B/etc.) you are closest to, not the actual frequency of the note you are playing.
Limited and inaccurate!
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 $2.99 like I did
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.
