🌙 sndflo

The story ends. The sounds don't.

You fall asleep to a bedtime story. Twenty minutes later it finishes, the room goes silent, and you're awake again. sndflo fades the narration out and keeps your sound mix playing — all night, or until your timer runs out.

The problem

The story works. You're drifting, barely following the words, right at the edge. Then it ends.

The narration stops, the room goes quiet, and the silence is loud enough to pull you back up. Or you drift off fine and a car door slams at 2am with nothing there to cover it.

Most sleep apps treat the story as the product. The sound underneath it is set dressing that disappears when the track is over. If you want white noise after, you have to open a second app — and by then you're awake enough that it doesn't matter.

How sndflo works

1. Build your sound bed. Layer whatever puts you under — rain and a box fan, brown noise and a campfire, airplane cabin and a waterfall. Every sound has its own volume, so you get the balance right instead of picking one preset and hoping.
2. Start a story on top of it. Pick a bedtime story. It plays over your mix, not instead of it.
3. The voice fades. The sounds stay. When the story finishes, the narration fades out and your mix keeps running. No gap, no silence, no waking up at 2am wondering what changed.

What else is in it

What it costs

The full mixer, binaural beats, timers, two saved mixes, seven sounds and five bedtime stories are free — not a ten-minute preview, enough to actually use every night.

The rest of the library is a one-time $19.99 unlock — not a subscription; you buy it and it's yours. (Most sleep apps run roughly $50–70 a year.)

FAQ

Do the background sounds keep playing after the sleep story ends?

Yes. The narration fades out and your sound mix continues — through the night, or until your sleep timer runs out.

Can I use my own combination of sounds?

Yes. Every sound layers independently with its own volume slider. Airplane cabin plus box fan, rain plus thunder, brown noise plus a campfire — whatever works for you. Save your favorites and load them with one tap.

Do I need to download an app?

Yes — sndflo is an iPhone app, free on the App Store, with an Android version coming. Everything plays offline once installed.

Will it keep playing if I lock my screen?

Yes. Lock the screen and the mix keeps playing until your sleep timer ends or you stop it.

Does it work offline?

Yes. Every sound and story ships inside the app, so nothing streams and it works in airplane mode.

Is it free?

Yes. The full mixer, binaural beats, timers, two saved mixes, seven sounds and five bedtime stories are free, with no account. The rest of the library is a one-time $19.99 purchase — no subscription.
