"This is so good because it will give you one hz number only. No numbers jumping all over the place. Good for a simple mind like I have. It will not give a reading at all if the tone is not pure and clean. Good for me looking into chakra healing sounds. So if there`s no reading, the tone is poor quality or dirty, and best of all, I`ve found it to be accurate to within 1 Hz."

"I`d been wanting something like this but didn`t know it existed so I hadn`t been looking. I found it by accident because I`d been searching frequency analyzers for a way to detect the frequency of my instruments. But analyzers are cluttered with controls and options that I don`t need and it can be difficult to read the data through the graphs and flashing lights. This tool provides exactly what I was looking for in an analyzer and I`ll also be able to use it for the functions it was designed for. It`s simple to use, easy to read, and accurate. The app rating system only offers stars but my personal rating is ``Hidden treasure.``"
