About this app

**LunaRest** is a next-generation sleep analysis app that visualizes the "truth about your sleep" using the latest AI technology.

【3-Stage Precision Analysis Engine】
Many conventional snoring detection apps simply react to "loud noises." This counts sounds like turning over in your sleep or outside traffic noise. LunaRest precisely identifies snoring in the following three steps:
1. RMS Analysis (Volume Judgment): Cuts out subtle ambient noise and extracts only those above a certain volume level necessary for analysis.
2. FFT Frequency Analysis (Tonality Judgment): Extracts low-frequency components characteristic of snoring and distinguishes them from background noise.
3. AI Analysis (Pattern Judgment): An AI based on Google's advanced acoustic recognition model "YAMNet" determines whether it is "real snoring" based on the sound waveform pattern, down to the 0.1-second level.
This three-stage filtering system achieves both overwhelming detection accuracy and power efficiency.

【Main Features and Characteristics】
• "15-Second Precision Recording" to Preserve Evidence
Automatically records 2 seconds before and 13 seconds after the moment snoring is detected (total 15 seconds). After waking up in the morning, you can play back from the list and hear for yourself "what kind of snoring you were doing." Because it captures the cyclical breathing rhythm, it enables stable recording that is not misled by single noises.

• "Volume Transition Graph" to Visualize the Night's Silence
Displays the maximum volume every 10 seconds from bedtime to waking up in a line graph. Regardless of whether snoring occurred or not, it is immediately clear how the quietness of the room changed and when the noise was most intense. The yellow line on the graph indicates the snoring recording point, perfectly synchronizing the volume and timing of the sound.

【Secure Privacy and Data Protection】
For those who are worried about recording sounds in their bedroom, rest assured. LunaRest is designed with privacy as its top priority.
• Offline Processing: All voice analysis and AI judgment are performed on your smartphone. Audio data is never transmitted to external servers.

* Data Management: Recordings and history can be deleted at any time at your discretion.

[Recommended for those who:]
* Have been told by family members that they snore loudly, but are unaware of it.
* Are worried about sleep apnea syndrome (SAS) and want to keep a record.
* Experience dry mouth or sore throat upon waking.
* Want to see the effects of changing pillows or bedding numerically.
* Want to hear their own snoring.

[Easy 3-Step Usage]
1. Place your smartphone by your pillow before going to sleep and connect the charger.
2. Press the "Start Measurement" button and sleep with the screen face down.
3. When you wake up, end the measurement by pressing "Slide to Stop." You can immediately check the detailed report.
Regain quiet, deep, and optimal rest with LunaRest.

This is an AI-powered snoring detection and recording app. It visualizes the changes in snoring volume throughout the night in a graph and provides accurate snoring duration and sleep advice.
