Ratings and reviews

App is difficult to use. There are alot of small symbols that can be difficult to recognize, as well as remember what they signify. I would rate ⭐⭐⭐⭐⭐ if the app had list of some type, in a drop down window for example, that spelled out each button's function. This app is extremely useful, very interesting, and fun to use. But it's degree of difficulty to operate and fully understand, makes it un-useable to most individuals that might download it.

Wow. Am very impressed with the wide range of features. You can switch to 24khz bandwidth, slide indicator to specific freqs, step history in 0.1sec increments, generate white, pink, gray noise etc., and switch among several views of the graphical output. Two notes: 1) tap the ellipses (...), read the question mark icon, and see what the icons do. 2) Some users complained about accuracy ... they should realize that a cell phone mic is NOT a studio reference mic. It's the hardware, not the app!

This app is great! I love seeing which colors correspond with which music notes, and there are lots of extra features that I wouldn't expect with a free app. Thank you for doing such a great job on this cool learning tool! The toggle feature for light and dark modes is nice too. Highly recommend to all science lovers out there!
