A sound in the background
Silence at bedtime can feel very loud. Many people simply like a soft, steady sound in the room while they wind down.
Sleep sounds, made on your phone
Soft sound for nights that feel too quiet.
Many people who live with ringing in their ears like a soft, steady sound in the background at night. Calmhum makes that simple: mix brown noise, soft rain and a fan, find a tone you like, set a timer and rest.

Why Calmhum
Quiet nights,
without the fuss.
No loops, no interruptions
Short recordings repeat, and ads break the calm. Calmhum makes each sound on your phone as you listen, so there is nothing to repeat and nothing to interrupt.
Just your phone
Earbuds in bed get uncomfortable. Calmhum is designed for the phone's own speaker, so you don't need headphones or any other device.
How it works
Three steps to a calmer night.
-
Pick your sounds
Turn on any of the 7 sounds and set each one's volume. Calmhum keeps the mix balanced as you add layers.
-
Find a comfortable tone
Move a slider, listen, and keep the tone that feels right to have on in the background. Play it as a pure tone or a soft band of sound.
-
Set a timer and rest
Choose 15 minutes to 2 hours, or all night. The sound fades out gently and keeps playing with the screen locked.
Try a sound
Layer a few sounds
and listen.
This preview runs in your browser and follows the app's mixing steps: layers are balanced as you add them, volume changes glide, and a limiter keeps the peaks soft.
Sound plays only after you press Play. It starts quietly and fades in over 3 seconds. Keep the volume low, just loud enough to be comfortable.
Ready when you are.
The preview stops when you leave this page. On iPhone, also check that the volume is up.
What's inside
Everything you need
for the night. Nothing more.

A tone you like
Slide from lower to higher, listen, and keep the one that feels comfortable. Use it alone or with other sounds.
Sleep timer
15, 30, 45, 60, 90 or 120 minutes, or all night. The sound fades out over the last 30 seconds.
Plays in the background
Keep listening with the screen locked or in other apps, with controls on the lock screen. A call pauses the sound, and it fades back in when the phone allows.
A short daily journal
Note how noticeable the ringing was and how you slept, from 0 to 10. See the last 7 days at a glance and share it as PDF or CSV.
Made for the dark
A calm, dim screen that is easy on the eyes at night, and a gentle reminder if your volume is high.
Privacy
Your nights stay
on your phone.
Calmhum has no server of its own. Your settings and journal are kept on your device and are never sent to us.
No account
No sign-up and no login. Calmhum never asks for your name, email or phone number.
No ads, no tracking
No advertising and no crash reporting. Usage statistics (which screens and features are used) help us improve the app; you can turn them off in Settings, and in Europe the app asks first.
Your journal stays with you
It leaves your phone only when you share it as a PDF or CSV file yourself.
Nothing is streamed
Every sound is made on your phone as you listen. Nothing is downloaded.
FAQ
Questions,
answered.
Do I need headphones or a speaker?
No. Calmhum is designed for your phone's own speaker. If headphones are connected, it plays through them, and it pauses if they disconnect instead of switching to the speaker.
Is Calmhum a medical app?
No. Calmhum is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. It does not replace advice from a doctor. If ringing in your ears starts suddenly, is in one ear only, or comes with hearing loss or dizziness, please see a doctor.
Will it keep playing when the screen is off?
Yes. It keeps playing with the screen locked and while you use other apps, until you stop it or the sleep timer ends.
Does the sound loop?
No. Each sound is generated continuously on your phone, so there is no recording to repeat.
Which devices does it work on?
iPhone and iPad with iOS 17 or later, and Android phones and tablets with Android 8.0 or later.
What does it cost?
Free for 7 days, then a subscription (monthly or yearly) or a one-time Lifetime purchase through the App Store or Google Play. Your journal stays available without a plan. There are no ads.
Where is my journal stored?
On your device only. It is not sent to us and is left out of device backups, so to move it to a new phone, share it as a PDF or CSV file first.
Where can I get help?
See the support page for common questions, or write to dys0707y@gmail.com.
