## What is Tone Generator Hz?

tonal.fm is a free tone generator app with 67 audio tools, no ads and no account. Play any frequency from 20 Hz to 20,000 Hz, fall asleep to brown noise with a sleep timer, test your speakers and hearing, and tune a guitar. Sound keeps playing with the screen off.

WHY TONAL.FM
• No ads, no account, no subscription
• Works offline
• Background playback with lock-screen controls
• Microphone audio stays on your phone

TONE GENERATOR
Any frequency from 20 Hz to 20,000 Hz with sine, square, triangle and sawtooth waves. Turn the dial, hold the readout to type a number, or tap a preset. The readout shows the nearest musical note.

SLEEP SOUNDS
White, pink, brown, green, gray, blue and violet noise, plus fan, with a sleep timer. Playback continues in the background with play and pause from your lock screen.

BINAURAL BEATS
Preset beat frequencies for focus, relaxation and sleep, with headphones.

TEST YOUR GEAR
A high-frequency hearing check (8–20 kHz) for curiosity, not a medical test or diagnosis, a speaker test for left, right and phase, and Fix My Speaker, which plays a low tone to push water out of a phone speaker.

HIGH-FREQUENCY TONES
A dog whistle with three cadences and a mosquito tone.

MUSIC
A metronome with tap tempo and a microphone tuner for guitar and other instruments.

FREE, NO ADS
Every tool opens for free and there are no ads. One optional purchase, tonal.fm Pro, is a single payment (not a subscription) that unlocks:
• an all-night sleep timer
• every binaural preset
• WAV or MP3 export of tones and test tones
• hearing test history

PRIVACY
No account. The app sends anonymous usage events only. Microphone audio for the measuring tools is processed on your phone and never leaves it. Policy: https://www.tonal.fm/privacy

## Version history (last 3 releases)

### 1.1.1 — 2026-11-12

Try sound till morning: Night on the Sleep timer is now free for one night.
A clearer Pro page that shows the price up front.
Links to binaural presets now open the tool straight away.
Small fixes.

### 1.1 — 2026-11-09

A whole new look, and it feels as good as it sounds.

• New design. Every one of the 67 tools now has a dark, tactile look with big dials, raised keys and live meters.
• New icon. The Dial.
• New Home. The three tools people search for most sit up top. Your recent and saved tools come next, with all tools grouped below.
• Tools, Saved and Pro tabs. Bookmark any tool, then drag to reorder your list.
• Haptics. Dials click as you turn them and land with a firmer click on round values. You can switch haptics off in Settings. Most haptics pause while the mic is listening, so tests stay accurate.
• Metronome. Adds time signatures (including 5/4 and 6/8), accent on beat one, a wood click, tempo names and an optional beat pulse you can feel.
• Tone generator. A new log dial with the note name, fine step keys and hold-to-type. Adds a stop timer.
• Sleep. A new timer ring, +15 min, and a rain layer over any noise colour.
• Binaural beats. Louder, with a new volume slider.
• Bluetooth headphones stay in full stereo while you use a mic tool. Decibel, Tuner, Spectrum and the other meters now measure with the phone's own mic.
• Settings. Haptics, restore purchase, support and version, all in one place.
• Better accessibility: larger tap targets, clearer contrast, VoiceOver labels and reduced-motion support.

Same price. Nothing removed. Your settings and Pro carry over.
