🌙 hear2sleep — Your Science-Based Sleep Companion

Developed by Dr. Phan Huu Phuoc, a practicing Geriatrician in Ho Chi Minh City, Vietnam, hear2sleep uses evidence-based audio principles to help you fall asleep naturally and stay asleep longer.

─── WHY hear2sleep WORKS ───

Most people listen to music wrong at bedtime. Shuffling through different songs or looping an entire playlist keeps your brain in an alert Beta wave state — making it harder to sleep.

hear2sleep is designed around a simple but powerful principle: ONE consistent track, looped on Repeat 1, gradually guides your brain from Beta waves into slow Delta waves — the deep sleep state.

─── KEY FEATURES ───

🎵 10 Curated Built-in Tracks

Handpicked instrumental music including piano, guitar, flute, ambient and romantic pieces — all composed for sleep.

😴 Sleep Timer with Fade-Out

Set a timer from 5 minutes to 4 hours. Music fades out gently so you stay asleep even after it stops.

🎶 Your Own Music

Add your own MP3 or WAV files from your device. Create a personal sleep playlist.

🧘 RelaxingMusic Tab

A dedicated space for your instrumental and relaxing tracks — kept separate from your other music.

🔂 Repeat 1 Mode

The scientifically recommended way to use sleep audio — one consistent sound that trains your brain to relax.

🔀 Shuffle Mode

For those times you want variety — though we recommend Repeat 1 for best sleep results.

📊 Sleep Stats

Track your listening habits over 7 days. Build a healthy sleep routine.

🫁 Breathing Guide

4-7-8 breathing technique animation to help you relax before sleep.

─── THE SLEEP FORMULA ───

1️⃣ Pick ONE track from Built-in

2️⃣ Set Repeat 1

3️⃣ Set Sleep Timer (30–60 min recommended)

That's it. Let the consistent rhythm guide your brain to sleep.
