Science Project

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 didnt 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 (Im 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.
