## What is NemuLog?

NemuLog is an offline sleep-sound recorder made for iPhone only. No Apple Watch and no account are required.

Place your iPhone by your pillow, tap start before sleep, and stop in the morning. NemuLog records overnight on-device, analyzes the full recording after you stop, then keeps only the loud peak moments as short clips so you can review your night quickly instead of listening back to hours of audio.

Main features
- One-tap start before sleep and stop after you wake up
- A 1-second volume timeline for the full night
- Peak-only clip extraction to save storage
- Estimated snore duration, max volume, and saved clip count
- Fast playback for the clips that matter

Privacy and scope
All recording and analysis stay on your device. No account, sign-in, or server is involved. NemuLog is not a medical device and does not provide diagnosis. It is a simple utility for reviewing sleep sounds privately on your iPhone.
