CH 01 – 06The desk
A mixing desk for your night.
Choose the sounds, adjust their volume and tone, and set a sleep timer.
Six channels, six faders
Pick a sound for each channel and set its level on a real fader with a 10 / 6 / 3 / 0 scale. The VU meter shows what each one is doing.
A tone knob per channel
One tilt filter centred between 250 Hz and 1 kHz. Turn it left for a darker, softer sound; right for more air.
Colour noise generated live
White, pink, brown, green and grey noise are synthesised in real time, not looped. No seams, no repeats, ever.
Sleep timer with a soft fade
Set 15, 30, 45, 60 minutes or your own. The mix fades out at the end instead of cutting. Free, no limit.
PATCH BAY29 sounds
Rain, fire, a night train, a coffee shop, a spaceship.
19 sounds are free; the catalogue contains 29. Save your favourite combinations as tapes.
TAPESYour mixes
Your tapes are yours. They never lock.
A mix is saved as a tape. Five are free, and every tape you save keeps working forever, even past the limit.
- Share as an image or a short code. A tape becomes a 1080×1080 card, or a code like HJ4K-9XQ2-MNT7 that any Fader can load.
- Export and import as JSON. All your tapes in one file you keep. Restoring never counts against the limit.
- Widget and shortcut. Play or pause the last tape from the home screen and see the timer.
- Nothing on a server. Tapes live on your phone and in your own Google backup. There is no account to lose.
NIGHTBedside
From bedtime to the alarm.
Wake up with your own mix
The alarm fades your tape in instead of ringing. Pick the days, snooze for 9, slide a fader to turn it off.
Night clock
A dim bedside clock with the timer and alarm at a glance. A total dark mode for rooms that need to stay black.
Bedtime reminder
One notification at the hour you choose. Tap it and your mix is on.
Works with no signal
Every sound ships inside the app. Airplane mode, a cabin, a tent: it all plays.
PROOne-time payment
One payment. Forever. Less than a month of a subscription.
Here is exactly what is free, what Pro adds, and where the ads are.

| Ads | Static native + optional rewarded | None |
No ads on app open. The free version can show static native ads in Tapes. Full-screen rewarded ads are optional, for a Pro sound for 24 hours or one audio import. They are not shown during playback, the night clock or an alarm; an alarm interrupts an already-open Google ad. Previously imported audio remains yours to use.
FAQ
What does the tone knob do exactly?
It is a tilt filter: one control that lowers highs and lifts lows when turned left, and the reverse when turned right, pivoting between 250 Hz and 1 kHz. It is enough to make rain feel further away or a fan feel closer, without touching an equalizer.
Are the noises real recordings?
The five colour noises are generated in real time by the app, so they never loop. The other 25 sounds are recordings, normalised to the same level so the faders mean the same thing on every channel.
Does it keep playing with the screen off?
Yes. Playback runs as a media service with the usual notification controls, and the timer keeps counting. If your phone has aggressive battery settings, allow Fader to run in the background.
What happens to my tapes if I change phones?
Android backup includes tapes and settings, but not imported audio files. Export a portable ZIP from Settings to keep available audio with your tapes. Old JSON backups remain importable but contain no audio. Missing originals need a surviving copy. Pro can be restored with your Google Play account.
Which languages?
English, Spanish, Portuguese, German, French and Japanese. The engraved labels on the desk (POWER, TIMER, TONE) stay in English in every language, like on a real console.
Is there an iPhone version?
Not yet. Fader is Android only, for phones on Android 8 or newer.
