Hear Outside does exactly one thing: it lets you hear the world around you while keeping your earphones in.
It passes whatever the microphone picks up straight to your earphones — a "digital pass-through." When someone calls your name or you don't want to miss an announcement, try hearing the world with your earbuds in.
■ One button, that's it
- Tap "Start" and outside sound flows straight into your earphones
- A gently swaying waveform shows the sound is coming through
■ Volume, your way
- Amplify from 0.5x up to 3x with the slider
- At 2x and above, Super Hearing mode kicks in — the giant ear on screen gets ridiculously big
■ Built with care
- To prevent feedback, it only starts while earphones are connected (it won't run on the speaker)
- It stops automatically on phone calls, app interruptions, or when your earphones disconnect
■ Your data
- Mic audio is processed on your device, solely to pass it to your earphones
- Audio is never recorded, saved, or transmitted anywhere
- The app shows ads (see the privacy policy for details)
Note: latency depends on your earphones (wired is lowest; Bluetooth varies by model).
Note: this app is not a hearing aid or a medical device.
