About this app

Neru is a minimalist sleep companion: mix soothing sounds, drift off with a gentle timer, wake up softly and understand your nights — all fully offline, with no account and no ads.
🌙 FALL ASLEEP TO SOUND
• A calm, distraction-free sleep timer — pick any duration, or let it play all night
• Sounds fade out slowly at the end, so they never wake you
• Add 5 minutes with one tap, pause by touching the dial
• A gentle 4-7-8 breathing rhythm pulses in the dial to slow you down
• Soft ambient scenes behind the timer: bubbles, stars, fireflies or aurora
🎵 YOUR PERFECT MIX
• Blend up to 5 sounds at once, each with its own volume
• Dozens of hand-crafted loops: lofi melodies, night piano, music box, rain, ocean, campfire, crickets, thunder, wind, fan, train, a purring cat, white noise, binaural delta & theta waves and more
• Import your own music and mix it with nature sounds
• Reliable playback with the screen off — no interruptions, no stutter
⏰ WAKE UP GENTLY
• Alarms with progressive ringtones: standard, birds, chimes — or any song you import
• Blend catalog sounds into your very own alarm sound
• Weekday schedules, per-alarm snooze, and a live "hours of sleep" estimate while you set the time
• Nap mode: close your eyes, Neru wakes you when the timer ends
📊 KNOW YOUR NIGHTS
• Automatic, sensor-free sleep tracking: your nights are estimated from your timer and alarms — nothing to wear, nothing to charge
• Weekly, monthly and yearly charts with your sleep goal, average, best streak, usual bedtime and wake-up time
• Rate your nights to spot what works
• Export your whole night history as a single backup file
🕯️ MADE FOR THE DARK
• Nightlight: an ultra-dim clock that won't light up your room
• Bedtime reminders that nudge you to wind down
• Deep dark theme with customizable accent colors
• Home-screen widgets
• Available in 27 languages
🔒 PRIVATE BY DESIGN
Your sleep is nobody's business. Neru works 100% offline: no account, no cloud, no ads, no tracking. Your data never leaves your phone unless you export it yourself.
Neru is free to use, with no ads and no subscription. A single one-time purchase unlocks the full sound library, larger 5-sound mixes, all ambient scenes, home-screen widgets and advanced statistics.
Sleep easy. Wake fresh. 🌙
Fall asleep to sound. Gentle alarms, sleep tracking, no account, no cloud.
