Description

Pure Hz is a precision audio frequency generator that lets you produce pure tones across the full audible spectrum — and beyond.

Whether you're testing your hearing, tuning an instrument, experimenting with sound, or simply curious about how frequencies feel, Pure Hz gives you complete control
in a clean, focused interface.

FREQUENCY CONTROL
Generate any frequency from 10 Hz to 80 kHz with a smooth logarithmic slider. Fine-tune with step buttons, or tap directly on a musical note. The large frequency
display always shows your exact Hz value along with the nearest note name and cent offset.

WAVEFORMS
Choose from four classic waveforms:
• Sine — The purest single frequency. Clean and smooth, ideal for hearing tests and tuning.
• Square — Strong odd harmonics. Sharp, buzzer-like character.
• Sawtooth — All harmonics present. The richest, most complex tone.
• Triangle — Weak odd harmonics. Softer than square, smoother than sawtooth.

HEARING TEST PRESETS
How good is your hearing? A healthy young ear can hear up to around 20,000 Hz — but that upper limit drops with age. Pure Hz includes age-based presets so you can
check where your hearing currently stands:
• Baby: ~20,000 Hz
• Teens: ~18,000 Hz
• 20s: ~16,000 Hz
• 30s: ~14,000 Hz
• 40s: ~12,000 Hz
• 50s: ~10,000 Hz
• 60s+: ~8,000 Hz

ANIMAL FREQUENCIES
Explore frequencies beyond human perception — the ranges that dogs, cats, dolphins, and bats use to communicate and navigate.

MUSICAL NOTES
Select any note across 8 octaves from a chromatic grid. Perfect for instrument tuning or music education.

FAVORITES
Save your frequently used frequencies with custom labels. Long press any saved frequency to rename it.

LIVE WAVEFORM VISUALIZER
Watch your waveform rendered in real time as the tone plays.

Pure Hz is ad-free and works completely offline.
