On-device sound awareness
Hear what matters, even when you can't.
Pulse listens in the background for your name, alert sounds, and important audio events, then gets your attention the moment they happen. Everything runs on your iPhone. Nothing is sent anywhere.
Built to run entirely on your phone, offline, with nothing collected.
Audio is processed in memory and discarded immediately. No accounts, no cloud, no analytics, no tracking.
Why Pulse
Name and sound alerts
Pulse recognizes your name and nicknames, plus important sounds around you, and alerts you right away.
Live transcription
Speech is transcribed in real time and matched against context, all without leaving your device.
Haptic patterns
Distinct vibration patterns let you tell alerts apart without needing to look at your phone.
Fully offline
No internet connection is required for any core feature. Pulse works the same in a basement as it does anywhere else.
No cloud processing
All inference runs on-device using the Neural Engine. Audio is never transmitted.
No tracking
We don't know who you are and we don't collect usage data. Your history stays on your phone.
