WhisperNote

A voice memo app that only records when you whisper. Quiet by design.

What it is

Tap once. WhisperNote watches the microphone for the unique spectral signature of whispered speech and starts recording when it hears one. Loud speech, fans, traffic, and clattering plates are ignored. Great for late nights, libraries, and sleeping kids.

Listening on-device

Audio is analysed by Apple's AVAudioEngine. Transcription happens on-device via Apple's Speech framework. There is no network traffic.

Private by design

No account, no cloud, no analytics, no third-party SDKs. Memos are stored on your device using SwiftData. Deleting the app deletes everything.
