• Use this app as an instrument for playing or producing music.
• Tune your musical instruments with musical notes presets.
• Test speakers for high end (treble) and low end (bass) tones.
• Discover how your audio handles sweeps of frequencies which range from ultrasound to infrasound.

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.
