iPhone
ClearTone is a real-time personal sound amplifier designed to help you hear conversations, television, and everyday sounds more clearly — all through your Bluetooth earphones.
HOW IT WORKS
Simply connect your Bluetooth earphones, tap the power button, and ClearTone instantly amplifies the sounds around you. Your iPhone's built-in microphone captures ambient audio, processes it in real time, and delivers clear, amplified sound directly to your ears.
KEY FEATURES
• Real-time sound amplification, adjustable from 100% up to 1500%
• Neural noise reduction (RNNoise) — reduces background noise, fan hum, and rustling sounds
• Multi-band clarity boost tuned for speech
• Automatic feedback (squeal) detection and suppression
• Independent left and right ear volume control
• Built-in hearing check that tests each ear separately and personalises your sound
• Tinnitus relief: gentle pink noise masking
• Works with AirPods, AirPods Pro, and all Bluetooth A2DP earphones
ABOUT BLUETOOTH DELAY
Bluetooth earphones add roughly 0.2 seconds of audio delay. This is a limitation of Bluetooth itself, not of ClearTone. It means the app works best for television, meetings, and voices at a distance. In close face-to-face conversation you may notice the sound arriving slightly late. The app shows the measured delay on its home screen.
DESIGNED FOR EVERYDAY LISTENING
ClearTone is ideal for:
• Watching television at a comfortable volume
• Following conversations in noisy environments
• Hearing clearly in meetings, restaurants, or public spaces
• Anyone who wants a personal volume boost without a hearing aid
IMPORTANT NOTICE
ClearTone is a general wellness audio utility, similar in function to Apple's built-in "Live Listen" feature. It is NOT a hearing aid, and is NOT intended to diagnose, treat, cure, or prevent any medical condition. If you have significant hearing loss, please consult a licensed audiologist or hearing healthcare professional.
