About this app

All frequency sound generator tools in one app! Tone generation, sound tests, musical tuning and many more. This app helps if you are looking for generating sounds in different frequencies, analyzing sound and making sound tests which produce sound waves based on the desired tone.

Frequency sound generator includes user-friendly and very high-quality tone generation tools:
• Single frequency generator
• Multiple frequency tone generation
• Musical notes presets
• Binaural beats
• SFX sound generator
• Sweep generator
• Bass/Subwoofer sound test
• DTMF tones
• Clean sound effects generator

Commonly used for:
• Make you own experiments with sound generation.
• Testing own hearing. Human ear is capable of hearing frequencies between 20Hz to 20000Hz.
• 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.
• Relax with binaural beats which play different frequencies in each ear.
• Find a way to mask your tinnitus frequency.
• Or have fun generating random sound effects, different frequencies and exploring all tone generation tools in this app.

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.

Ratings and reviews

Not very useful, VERY motivated to sell. Not a lot of customization for binaural - can't specify wave shape, amplitudes. Non-skippable rating screen before you can do anything - only 5 stars are referred to the Play store to rate. Can't save anything without signing up for subscription. Opened a map randomly, twice, within the app - I assume to sneak location data. There's a picture of a button to change ad preferences, but it doesn't actually respond when you tap it. Really, just the worst.

Playing with multiple simultaneous frequencies is interesting and affects the overalll sound output in ways I couldn't have imagined or foreseen. It'd be nice if I could play it in the background while using other apps in the foreground. That way, I could test different frequency combinations and their effect on my focus ability. I might find something therapeutic for me. Probably not, but it's a possibility.

According to Sophos Intercept X, this app is a "low reputation app", in that it gives itself full access to everything on your phone and can run in the background without you knowing it, making it a security risk. The issue's not just that the app could be malicious, but that malicious actors could take advantage of the invisible, unused permissions of an app. The Google Play Store should know better than to allow apps to request permissions they don't need. I guess I should rate the Play Store.
