Ear Assist vs Smart FM+

Make voices, TV and lectures louder through your headphones. Ear Assist turns your iPhone or iPad and a pair of headphones into a sound amplifier. It picks up sound through the microphone and plays it louder in your ears, so you can follow the lecture from the back row, keep the TV at a volume that suits you, or catch the conversation at a busy table. LOUDER WHEN YOU NEED IT • Volume control plus Boost: add +6, +12 or +18 dB with headphones • Boost is switched off on the loudspeaker, where it would cause a feedback howl, and limited on the earpiece • The Boost button always shows the gain that is actually applied TWO WAYS TO LISTEN • Natural: the sound as the microphone picks it up. Best for music, birdsong and the atmosphere of a room • Speech: uses Apple's voice processing to reduce background noise and echo. Best for conversation, meetings, lectures and TV SHAPE THE SOUND (EAR ASSIST PRO) • Five-band equalizer from 60 Hz to 14 kHz • Lift the upper bands to bring voices forward, or cut low rumble • Save settings for different places and load them again later YOUR HEADPHONES, YOUR MICROPHONE • Works with wired headphones, AirPods and other Bluetooth headphones • With Bluetooth headphones, Ear Assist uses your iPhone's microphone and keeps full stereo sound, unless you choose the headset microphone • On iOS 26, choose your microphone from the system input menu. Your choice is remembered RECORD LECTURES AND TALKS (EAR ASSIST PRO) • Record what you are listening to, saved on your device as M4A files • Recording starts only when you tap Record, and stops when you tap Stop • Please ask permission before recording other people ABOUT DELAY Listening live through headphones always involves a short delay between the microphone and your ears. It is shortest with wired headphones. Bluetooth headphones add more, and if you can also hear the sound directly you may notice a slight echo. Where delay matters, use wired headphones. GOOD FOR • Lectures, talks and the back of a hall • Meetings and busy restaurants • TV at your own volume without disturbing others • Theater, places of worship and events from far seats • Birdwatching and nature recording PRIVACY Audio is processed on your device. Ear Assist does not upload what it picks up or what you record. The free version shows ads, and the app uses analytics and crash reporting; the App Privacy section on this page lists what those services collect. EAR ASSIST PRO Ear Assist is free with ads. Ear Assist Pro removes the ads and adds recording and the equalizer. Choose a monthly or annual subscription, or a one-off lifetime purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period, and you can manage or cancel them in your App Store account settings. If you bought any feature in an earlier version, Pro is already included. IMPORTANT Ear Assist is an entertainment and convenience utility for listening through headphones. It is not intended to diagnose, treat or cure any condition, and it is no substitute for professional advice or care. If you have any concerns about your ears, speak to a healthcare provider.
