About this app

Generate pure sine wave tones at frequencies from 20hz to 22,000hz. Tone generation is useful in tuning instruments, hearing tests, science experiments, and testing audio equipment.

Tone Generator has many uses:
- Hearing Test: What is the lowest/highest frequency you can hear in each ear?
- Tuning Instruments: Does your top guitar string match Low E at 440 Hz?
- Science Experiments: What is the resonant frequency of your wine glass?
- Audio System Test: What frequencies does your subwoofer support?

Directions:
Adjust audio frequency by dragging the slider or tapping the plus/minus buttons. Adjust device volume using the on-screen volume slider. Toggle audio playback using the Play/Pause button.

As a TMSoft fan I had to give this try when I was looking for a tone generator. It works but I can't say much more. The volume is horrible even with a volume booster. I'm not sure why this is but I wish I could make it louder. Additionally there is no notation of musical scale which would be a nice option as well. Otherwise it's no frills and works without issue. The app is also very small.

Great for restaurants with screaming children or people at tables on speakerphone, a nice tone to aggravate everyone right back. The agony it causes children is so fun to watch.

Overall the app works well but it desperately needs the ability to type in the desired frequency. The slider bar is inaccurate, especially at higher frequencies (10k-22k), and you'd have to press the up or down buttons hundreds of times to get where you meant to be.
