Noise Shield

Noise Shield removes background noise and turns down crowd chatter in real time, through the earbuds you already own. No special hardware, no account, and your audio never leaves your phone.

LIVE: HEAR PEOPLE, NOT NOISE
Your phone's microphone listens, on-device AI removes the background, and you hear the cleaned sound in your earbuds.
- Nearby only: lets the person talking to you through while distant chatter fades
- Chatter cover: a soft sound that hides what's left of the crowd
- Voice boost and clarity to make speech easier to follow
- Profiles for Office, Cafe and Metro, or save your own

FOCUS: COVER THE NOISE
A soft brown, pink or white sound that measures your room and adapts to it. Great for studying, working in open offices, shared rooms and sleep.

RECORD: CLEAN VOICE NOTES
Record anywhere, remove the background noise, and compare the original with the cleaned version. Save both as WAV.

PRIVATE BY DESIGN
All processing happens on your device. No account, no cloud, no analytics, no ads.

HEARING SAFETY
A built-in loudness limit protects your ears, and Live mode stops automatically if your earbuds disconnect.

GOOD TO KNOW
- Earphones are required for Live mode.
- Noise Shield is not active noise cancellation: sound that leaks past your earbuds still reaches your ear, and Bluetooth adds a short delay. A good earbud seal does most of the blocking; Noise Shield cleans what comes through the app.
- Noise Shield is not a medical device or hearing aid.
