## What is Hearing aid app?

ngHero turns your iPhone into a smart, real-time hearing aid — no special hardware required.

REAL-TIME SOUND AMPLIFICATION
Amplify the sounds around you instantly through your built-in mic, Bluetooth, or wired headphones. Hear conversations, TV, and everyday sounds more clearly, wherever you are.

PERSONALIZED HEARING TEST
Take a quick, guided hearing test for each ear and get your own personal hearing chart in minutes. Save the result as a profile that automatically tunes the app to your hearing.

AI NOISE REDUCTION
Advanced AI filters out background noise in real time, so voices stay clear even in noisy places like cafes, streets, or family gatherings.

FULLY CUSTOMIZABLE SOUND
Fine-tune Bass, Mid, and Treble with the built-in equalizer, balance volume between your left and right ear, and choose your preferred microphone (built-in, Bluetooth, or wired).

RECORD & REPLAY
Record conversations or important moments and play them back anytime, with waveform scrubbing and bookmarks so you never miss a word.

MULTIPLE PROFILES
Create separate hearing profiles for different people or environments and switch between them instantly.

MULTIPLE LANGUAGES
Available in 45+ languages.

IMPORTANT
ngHero is a personal sound amplification app for everyday listening. It is not a certified medical hearing aid and does not diagnose, treat, or replace a professional evaluation of hearing loss. The hearing test is for reference only, to help estimate hearing sensitivity with your current device. If you have concerns about your hearing, please consult a licensed audiologist or ENT specialist.

SUBSCRIPTION
Each session gives you a few free minutes to try the app. Continued full access requires an auto-renewable subscription (monthly, quarterly, 6-month, or yearly). Payment will be charged to your Apple ID account at confirmation of purchase. Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. Manage or cancel your subscription anytime in your App Store account settings.
