Notes: • This app supports decimal values as input for frequencies when generating a tone. • This app makes an animated sound wave which tries to visualize a current frequency. • There are several waveforms available: sine, square, triangle and sawtooth. • Clean UI makes navigation simple through the navigation bar or pages where there are more frequency sound generating tools available. • Customize how the app behaves through settings menu where you can change themes, enable octave buttons, decimal points and more. • Phone speakers are not high-quality audio sources and may vary in quality. Sometimes a "parasite" noise can be generated by those speakers in very low or high frequencies which don't define the frequency. • Turn the volume down when creating high frequencies to not cause any discomfort when experimenting with the app. Privacy policy: https://dczt.dev/eula-terms-of-use.html Terms of use: https://dczt.dev/app-privacy-policy.html
