| 2022-09-10 |  | | Used this for ages to measure mechanical frequency. Now says 11098Hz whatever I try to measure. |

| 2020-09-10 |  | | This is wonderful app. More useful in engineering parlance. Musical notes, voice can hv many modulations. But there are applications where this is very useful. Phone microphone quality, distance can influence results greatly. One need to take 5 to 6 readings and choose the one most repeated. Awesome app. |
| 2019-02-19 |  | | Its a terrible app. The results aren't accurate at all. I tried playing one music five times at the same sound level and results are far from each other. |
| 2017-11-24 | | | Does not work . Android 7 |
| 2017-07-08 | | | Useful for identifying the exact frequency of a pure tone. I only awarded "2 stars" because: Contrary to developer's claim, app does NOT actually identify the "fundamental" tone within a sound that has harmonics ("fundamental" is the lowest freq in a series of harmonics and is normally associated with "pitch"). Instead, app merely identifies "peak frequency". App often reads an octave higher for human voice singing/holding a single note. Seems accurate for sustained pure tones, but does not work well for transient sounds like drums. Also, graph is not working on Samsung Galaxy Core Prime, Android 5.1.1. |
| 2017-02-25 | | | The worst. In does not even functioning properly as soon as i open it. |
| 2017-01-18 | | | App doesn't graph/ give options on how this works. S5 |
| 2016-11-09 | | | Only give the frequency but not the plot |
