AbhiNidra: Sleep & White Noise

Most nights, you don't need more melatonin. You need the right sound.

AbhiNidra — Sanskrit for deep sleep — is an offline sleep sounds and white noise app for people who take rest seriously. No account. No internet. No ads anywhere in the app. No subscription, ever.

━━ WHY ABHINIDRA IS DIFFERENT ━━

✦ ADAPTIVE VOLUME
Your phone listens to the room and lifts the mix to mask a sudden noise — traffic, a dog, a slammed door — before it wakes you. Processed live, never recorded.

✦ SLEEP RITUAL AUTOMATION
Run your whole wind-down hands-free. Chain 8 steps: sound, volume ramps, breathing, crossfades, screen dim, Do Not Disturb, pause and fade to silence. Or start a built-in one: Midnight Descent, Quick Anxiety Relief, Drift Off Gently, Deep Work Focus, Morning Energizer.

✦ AUDIO SUNRISE
Wake to a mix that fades in slowly before your wake time. No jolt, no buzzer.

✦ FREE APP, ONE-TIME PURCHASES
37 sounds are free. Optional Baby, Focus and ASMR packs add 28 more — each a one-time purchase, kept for life.

━━ SLEEP SOUNDS BUILT FOR DEPTH ━━

Included free: rain, thunderstorms, ocean waves, forest, crickets, campfire, fans, trains, airplane cabin, plus white noise and brown noise for masking. The optional packs add womb and lullaby sounds, focus and study ambience, ASMR textures and binaural beats. Every track loops seamlessly, no jarring cut on repeat. Plus a one-of-a-kind India collection: monsoon rain, temple bells, village nights.

Layer up to 5 sounds with independent volume on each — rain over brown noise with distant thunder. Save unlimited mixes and reload them in a tap.

5-BAND EQUALIZER + SPATIAL AUDIO
Boost the rumble in thunder, soften harsh white noise, widen the stereo field on headphones. Free.

━━ GUIDED BREATHING ━━

Five techniques — box breathing, 4-7-8 pranayama, coherent breathing and more — with haptic pacing so you can follow along, eyes closed. Build a streak, or chain breathing into a ritual that flows into your sleep mix.

━━ PRIVATE SLEEP TRACKER & DREAM JOURNAL ━━

A 30-second morning check-in logs duration, quality, mood and dream notes, stored only on your device. After three nights, unlock streaks, 7-day quality charts, a 30-day calendar and dream-theme insights. Export to CSV or JSON, or back everything up in one tap. Your sleep data is yours.

━━ SLEEP SCHEDULE & WIND-DOWN ━━

Set a wake time and sleep goal. AbhiNidra derives your bedtime, reminds you to wind down, and supports a separate weekend wake time.

━━ OLED BEDSIDE MODE ━━

A burn-in-protected nightstand clock and night light. Dim, minimal, kind to your eyes at 3 AM.

━━ SMART SLEEP TIMER ━━

Fade-out sleep timer with one-tap +15 minutes, plus smart idle detection that senses you've fallen asleep and stops playback.

━━ HOME-SCREEN WIDGETS ━━

Play, pause, extend or stop without unlocking your phone.

━━ WHO IT'S FOR ━━

- Masking tinnitus with steady broadband sound
- Noisy neighbours, a snoring partner, thin walls
- Shift workers sleeping through daylight
- Deep work, study and focus sessions
- Meditation and relaxation
