Everything for the night, nothing you don’t need

Sounds to fall asleep to and a recorder you can trust, designed to work together.

Sounds that never loop

White, pink and brown noise, rain, ocean and fan are generated live on your phone, so there is never a loop seam. Mix layers, set each volume and save your favourites.

Record while sounds play

Nightbox knows exactly what it is playing and removes it from the recording, so your sound machine doesn’t drown out the night.

Learns your room

A 20-second calibration learns your fan, air conditioner or room noise, so steady noise isn’t counted as snoring.

A clear morning report

A snore score from 0 to 100, time spent snoring and how loud it got, plus a timeline you can zoom into and tap to play.

Fix any wrong guess

Mark a clip “Not snoring” or “That’s my partner”, and the score updates straight away. Every clip is yours to play, free, forever.

Learn what helps

Tag your nights with what you did: a late meal, alcohol, a nasal strip, side sleeping. Over time, see what makes a difference.

Thai signature sound

Rice field after rain

Frogs and crickets in a Thai rice field after the rain: banded bullfrogs, rice-field frogs and a chorus of crickets, generated live so the night never repeats.

Designed for the dark

Your nights stay on your phone

Nightbox has no account and no server. Sound is analysed on your phone and recordings are stored only there. We can’t see your nights, and we don’t want to.
