ClearTone: Sound Amplifier

Hear every conversation clearly — powered by AI noise reduction and real-time sound amplification.

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 crystal-clear, amplified sound directly to your ears.

KEY FEATURES • Real-time sound amplification up to 100× gain • AI Neural Noise Reduction — removes background noise, fan hum, and rustling sounds • Two-stage denoising: RNNoise + GTCRN deep learning model for natural, clean audio • Independent left and right ear volume control • Tinnitus relief: gentle pink noise masking • Personal audio calibration to match your hearing profile • Ultra-low latency (~15ms standard, ~40ms with AI denoising) • Works with AirPods, AirPods Pro, and all Bluetooth A2DP earphones

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. ClearTone does not require FDA clearance or any medical device registration. If you have significant hearing loss, please consult a licensed audiologist or hearing healthcare professional.

REQUIREMENTS • iPhone with iOS 16.0 or later • Bluetooth earphones (A2DP compatible) • Microphone permission required
