Hear the conversation again — with the iPhone you already own. iHear turns your AirPods or wired headphones into a personal listening assistant. It measures your hearing in about five minutes, then amplifies the world around you to match your own ears: more where you need it, less where you don't. HOW IT WORKS 1. Take the hearing test. A guided tone test, one ear at a time, across six frequencies from 250 Hz to 8 kHz. About five minutes, in a quiet room. 2. Get your profile. iHear builds your audiogram and calculates the gain you need with NAL-R, the prescription formula used by audiologists. 3. Put your AirPods in and listen. iHear picks up the sounds around you and plays them back amplified, in real time. WHAT'S INSIDE • Clinical hearing test — Hughson-Westlake ascending method, each ear tested separately • Personal audiogram — see exactly where your hearing drops off • Real-time amplification across 6 bands, prescribed from your own results • Three listening programs — Quiet, Speech and Outdoors • Adaptive compression (WDRC) — quiet sounds come up, loud sounds stay comfortable • Anti-feedback — cuts in automatically before whistling can build • Maximum volume limit — set your own ceiling so nothing is ever too loud • Anti-echo and anti-resonance for reverberant rooms • Smart activation — amplifies only when there is speech or music • Mute my own voice, directional microphone, automatic gain • Manual equalizer if you want to fine-tune anything yourself BUILT FOR AIRPODS Low-latency processing keeps the amplified sound in step with what you see, so voices and lips stay in sync. Wired headphones work too. YOUR DATA STAYS ON YOUR IPHONE Your hearing test, your audiogram and your settings never leave the device. No account required — you can use iHear as a guest. Nothing is uploaded, nothing is sold. PRICING The hearing test, your audiogram and the equalizer are free. Real-time amplification is part of iHear Premium, with a 7-day free trial. Cancel any time. IMPORTANT iHear is a sound-amplification app for everyday listening situations. It is not a medical device and does not diagnose or treat hearing loss. The hearing test is a screening tool, not a clinical audiogram. If you have ear pain, sudden hearing loss, ringing, discharge, or hearing that is clearly worse in one ear, see a doctor or an audiologist.

Verdict
The clearest difference is in-app purchases: Otnac at none against iHear's 3. Otnac also leads on update cadence (every 3 weeks vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
