About this app

Nidoria is your personal sleep companion — designed to help you fall asleep faster, sleep deeper, and wake up at the perfect moment in your sleep cycle.

Whether you struggle with restless nights, snoring, or groggy mornings, Nidoria gives you the tools and insights to take control of your sleep, one night at a time.

★ KEY FEATURES ★

• SMART SLEEP TRACKING
Nidoria uses your phone's motion sensors and microphone to silently track your sleep stages — light, deep, and REM — all night long. No wearable required.

• SNORE & SOUND DETECTION
Advanced on-device audio analysis detects snoring, talking, and environmental noise so you can understand exactly what's disturbing your rest.

• SMART ALARM
Wake up gently within your chosen window, at the lightest point of your sleep cycle. Say goodbye to jarring wake-ups and morning grogginess.

• BEDTIME ALARM & WIND-DOWN
Set a bedtime reminder, choose from a curated library of calming ambient sounds, and ease into sleep with consistent, healthy sleep hygiene.

• DETAILED SLEEP REPORTS
Get a clear breakdown of every night: total sleep time, sleep efficiency, time in each stage, interruptions, and trends over days, weeks, and months.

• SLEEP HISTORY & STREAKS
Build healthy habits with streak tracking. Visualize progress with beautiful charts and stay motivated to keep improving.

• AMBIENT SOUND LIBRARY
Choose from a selection of soothing sounds — rain, ocean, white noise, and more — to help you drift off naturally.

• PRIVACY-FIRST DESIGN
All sleep analysis runs locally on your device. Your audio is never uploaded or shared. You stay in control of your data.

★ WHY NIDORIA? ★

Modern life is loud, fast, and exhausting. Sleep is the foundation of your physical and mental health — but most of us don't know what's really happening when we close our eyes.

Nidoria turns your smartphone into a quiet, intelligent sleep lab. Place your phone beside you, press start, and wake up to insights that actually help you sleep better.

★ PERFECT FOR ★

• People who wake up tired despite "enough" sleep
• Snorers who want to understand their patterns
• Shift workers managing irregular schedules
• Anyone building better sleep habits
• Light sleepers seeking a gentler wake-up

★ HOW IT WORKS ★

1. Set your bedtime and wake window.
2. Place your phone near your pillow or on your nightstand.
3. Tap Start and let Nidoria do the rest.
4. Wake up to a smart alarm and a detailed sleep report.
