Generate pure tones from 1 Hz to 22 kHz with sine, square, sawtooth, and triangle waveforms, frequency sweep, and dual-tone output — replace expensive lab equipment with the phone you already carry.

▶ MAIN FEATURES
• Sine, square, sawtooth, and triangle waveforms
• Full 1 Hz – 22 kHz frequency range with 0.1 Hz precision
• Frequency sweep mode (rises or falls over time)
• Dual-tone and stereo output with independent channels
• Adjustable volume and left/right balance
• Precise frequency entry by slider or number
• Function generator and signal generator in one app
• Speaker, subwoofer, and hearing test tones
• Dark mode for studio and night use
• Works fully offline — no internet required

▶ HOW TO USE
1. Pick a waveform (sine gives the cleanest pure tone).
2. Set the frequency with the slider or type an exact value (e.g. 440 Hz).
3. Adjust the volume to a safe, moderate level.
4. Tap Play — the tone outputs instantly.
5. Use sweep or dual-tone mode for response and channel testing.

▶ WHO USES TONE GENERATOR
• Audio and AV engineers calibrating systems
• Musicians and instrument tuners working to exact Hz
• Speaker and subwoofer testers checking drivers
• Electronics hobbyists testing circuits and filters
• Science and physics students exploring sound and frequency
• Hearing-range testers generating reference tones

Use a moderate volume to protect your hearing and your speakers — high-frequency tones at high levels can cause damage. Start low and increase gradually. ## Rankings - #1,138,418 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.MODIFY_AUDIO_SETTINGS` - `android.permission.RECORD_AUDIO` - `android.permission.WAKE_LOCK` - `com.amazon.privacypass.ATTEST` - `com.android.vending.CHECK_LICENSE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.google.android.gms.permission.AD_ID` - `com.simonj.tonegenerator.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Audio Frequency Generator](https://chrome-stats.com/d/org.uxeer.audiofrequencygenerator) — 1,614 users - [Tone Generator](https://chrome-stats.com/d/com.cxema.tonegenerator) — 584 users - [Tone Generator](https://chrome-stats.com/d/com.kirsulab.tonegenerator) — 53 users - [Tone Generator](https://chrome-stats.com/d/org.mobile.tgenerator) — 1,823 users - [Frequency Sound Generator](https://chrome-stats.com/d/com.helavidasa.fsg) — 359 users - [ToneGen Tone Generator](https://chrome-stats.com/d/com.nchsoftware.tonegen_free) — 38,954 users, 4.11 / 5 - [Tone Generator: Frequency & So](https://chrome-stats.com/d/com.epsilonv.highfrequencytonesignalgenerator) — 89,626 users, 3.74 / 5 - [Tone & Go: Frequency Generator](https://chrome-stats.com/d/com.andgoapps.tone) — 3,604 users, 4.00 / 5 - [Tone Generator & Visualizer](https://chrome-stats.com/d/com.AIDatskoStudio.Frequency.Tone.Generator) — 1,005 users - [Multi-Frequency Tone Generator](https://chrome-stats.com/d/net.audiotuner.tonegenerator) — 26,674 users, 4.00 / 5 - [Frequency and sweep generator](https://chrome-stats.com/d/com.freemiumapps.functiongenerator) — 117,159 users, 4.65 / 5 - [Tone Generator](https://chrome-stats.com/d/de.heinz.tonegenerator) — 23,122 users, 3.09 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.simonj.tonegenerator)
