Sleep recordings
Sleepr listens on-device and surfaces the moments that matter — snore clips, sleep talking, and quiet nights. Replay the night events and discover what you never knew.
Daily routine
Small, science-backed habits add up. Track caffeine cut-offs, morning sunlight, screen-free wind-downs, and a consistent bedtime — then watch your streak grow.
Smart alarm
Set a smart wake window and Sleepr nudges you awake during a lighter phase of your cycle — so mornings feel gentle instead of jarring.
On-device intelligence
Sleepr listens with a custom machine-learning model that identifies the sounds and patterns of your night — and it all happens locally, on your device. Your audio never touches a server.
Sleepr's own machine-learning model was trained to recognise the specific sounds of a night — snoring, sleep talking, coughing, and movement — not generic audio.
Every sound is classified in real time by your iPhone's Neural Engine. No servers, no round-trips — it even works in airplane mode.
The microphone stream is analysed and immediately discarded. There is no recording to upload, leak, or subpoena — only the labels you see.

The Sleepr difference
Most sleep apps upload your audio for analysis. Sleepr doesn't. Every snore, cough, and movement is processed in real time on-device — there is no audio recording to upload, leak, or subpoena. The only thing leaving your phone is the sleep summary you choose to sync.
On-device microphone analysis. Audio is processed in real time on your iPhone and never uploaded to any server.
Detects snoring, talking, coughs, and movement throughout the night — without sending audio anywhere.
