Works with screen off

Start recording before sleep and lock your phone. NightMic keeps listening in the background through iOS background audio.

🔒

Stays on your device

All recording and analysis happens on-device. No audio is ever uploaded to any server. Your sleep data is yours alone.

Frequently asked questions

Does NightMic upload my recordings?

No. All audio and analysis results stay on your iPhone. There are no servers, no cloud processing, and no syncing of any kind.

Will it keep recording if I lock my phone?

Yes. NightMic uses iOS background audio mode so recording continues after the screen is off. Place your iPhone near the bed with the microphone uncovered.

How accurate is the snore detection?

NightMic uses local audio analysis to identify loud, rhythmic segments that may be snoring. It is not a medical device and cannot diagnose any condition. Results are for personal reference only. Other sounds in the room (pets, TV, a partner) may also be flagged.

How do I delete my recordings?

Open Settings inside the app and tap "Delete All Recordings and Records." You can also delete individual sessions from the session detail view. Deleting the app removes everything.

What iOS version is required?

NightMic requires iOS 17.0 or later.

Can I export my data?

Yes. From any session detail view, tap Export to share the full audio recording via AirDrop, Files, or any other share destination.
