## Tone Generator Description
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.  You can also specify to play audio to any AirPlay supported device.  Toggle audio playback using the Play/Pause button.

Created by the audio experts at TMSOFT that brought you the famous White Noise app.  Check out all our apps and sounds at

## Tone Generator Reviews in United States

### ***** "Nice Basic Generator!"
Very simple interface, great for just generating a pure (sine wave) tone across the audio spectrum. Quick, easy way to check out the frequency response of your audio system, or your own ears. Use with caution, keeping the volume at a moderate level. Has a nice waveform display, too.
-- The gufuff, 2026-09-12

### *---- "Buggy"
No play pause button???
-- sputnik01, 2026-09-02

### ***** "Good sine wave tool"
Good simple  tone oscillator, can double as a tuning source for musical instruments. A4 = 440.  Presets can be created for stringed instruments.
-- RR4053, 2026-07-26

### ***** "best one i could find!"
best one i could find, simple and does exactly what it needs to and has the ability to go much louder than the others. but can you make it go below 20 hz? like down to 5 or something?
-- flyspeed702, 2026-07-25

### ***** "Let’s gooo"
The app design is great. The program is great.
-- VVXXIIIII, 2026-06-30

### ***-- "Need change bad"
It would be great if you can do up to 10 tones playing all at the same time but it’s only subpar
-- Yestbe, 2026-06-02

### ****- "Slide Control Only"
Being able to choose frequencies with a keyboard would be much more user-friendly than a slider.  In cases where small adjustments in frequency are required, and the exact frequency is not known beforehand, '+' and '-' buttons would come in handy.

Update:  The developer instructed me to upgrade the app, which happened automatically when I opened it.  When the app is opened, a frequency is displayed on what is actually a field for entering a frequency number, but which looks like a button-shaped display.  Not the most intuitive choice.  I would have gone with something that spelled that out, say, "Enter frequency.".
-- Medoohla Oblaghandi, 2026-05-28

### *---- "Ruined"
The last update ruined the ability to control the volume of the tone.
-- Lomax1972, 2026-05-21

### *---- "Awesome…"
You totally ruined what you introduced to us. Hurrrrdurrrrr cool app yo

Um no.
-- cuezaireekaa, 2026-04-30

### **--- "limited listening ability"
I love this app for the ability to choose the exact Hz frequency you want.  I hate, & will be deleting the app after this, bc I want the frequency to remain playing in the background when I’m using other apps, such as watching a YouTube video.  I want the frequency playing quietly in the background of whatever other audio I’m listening to.
-- ĸray8014, 2026-02-16

### *---- "Ad bar blocks control"
No audio output after ad block arrived
-- Graystoke1872, 2026-01-20

### ***** "Hawaiian approved 🤙🏽🙏🏽🏄🏽‍♂️🏝️"
Thank you guys you guys are soo awesome God Bless ✝️🙏🏽🤙🏽🏄🏽‍♂️🏝️♈️
-- HawaiianHammah_71, 2026-01-09

### ***** "#codeβreaker"
#codeβreaker💚💖💙🖤
-- Gunthai, 2026-01-09

### ***** "Simple and Effective"
To experience and evaluate my hearing this app is helpful. I have professional audiograms made by audiologist. Looking at the audiogram alone does not provide a physical sense of what my hearing loss sounds like across frequencies. Using the app I can hear what my ears are capable of across frequencies.
-- evetssark, 2025-12-13

### ***** "Garry"
Perfect tool I love it!
-- Masterclassic, 2025-11-23

### ***** "Perfect tool for no charge"
It works every time, no complaints.
-- sarras1, 2025-10-01

### ***** "Dr Partha"
These puretones are very meditative and very rad to use. Thank you
-- T K Parthasarathy, 2025-09-30

### ***** "Fantastic"
Soothing
-- Sia Cosca, 2025-09-21

### ****- "Below 20 Hz."
I remember being a board 15-year-old and wondering how many Hz I could hear below 20 with earbuds on but didn’t find an app that went down to one. I know most humans can’t hear below 20 Hz.
-- M L I R 13, 2025-09-18

### *---- "No Sound"
?? I get no sound generation on my iPad. What am I missing here?
-- JCS9148, 2025-08-27
