Simple Tuner and Spectrometer

Simple Tuner and Spectrometer is an awesome and simple app. It features a simple tuner and a simple spectrometer, for tuning instruments and metering audio.

The simple features include:

1. Working
2. Being simple
3. Having only one window without ads
4. Tuning from 50Hz to 2kHz, for different instruments
5. Spectrometer with a vertical cursor for checking specific frequencies
6. A completely unnecessary waveform display to fill in the rest of the window

The spectrometer uses a new and exciting breakthrough technology called Fast-Fourier Transform that’s only been in existence for one and a half centuries. The pitch recognizer uses a modification of the AMDF algorithm.

The app features both Light and Dark themes.
