iPhone
HearGuard turns your iPhone into a simple, honest sound level meter. Measure the noise around you in real time, track your daily noise dose, and stay aware of your hearing health - all on-device.
PROTECT YOUR HEARING BEFORE IT'S TOO LATE
The World Health Organization estimates that over 1 billion young people are at risk of noise-induced hearing loss. It's permanent, painless at first, and largely preventable. HearGuard gives you the awareness you need to act before the damage is done.
REAL-TIME SOUND LEVEL METER
- Live decibel readings on a clear, easy-to-read meter
- Min, max, and average levels for every measurement
- Color-coded safety zones: see quiet vs. loud at a glance
- Approximate readings for everyday awareness (not a professional instrument)
DAILY NOISE DOSE
- Noise dose tracking based on the NIOSH 85 dB / 8-hour guideline (3 dB exchange rate)
- Time-at-level breakdown shows how long you spent at each level today
- Health insights tailored to where you spend your time, with cited sources (WHO, NIOSH, CDC)
MEASUREMENT HISTORY
- Every finished measurement is saved automatically
- Review your most recent measurements for free
PREMIUM FEATURES (HearGuard Pro)
- Unlimited measurement history (Free: last 3)
- 7-day noise dose trend chart
YOUR PRIVACY MATTERS
HearGuard processes all audio entirely on your device. We never record, store, or transmit your audio - only sound levels are measured.
HearGuard is not a medical device and does not diagnose, treat, or prevent hearing loss. Sound levels are approximate and can vary between devices. For concerns about your hearing, consult a qualified professional.
Download HearGuard today and take control of your hearing health.
