Simply Sleep Sounds
Five colors of noise. Dark by default. Designed for actual sleep — not a feature-bloated meditation platform.
Five colors of noise.
The same physical signals you'll find on Wikipedia — generated live on your phone, not streamed. Pick one. Tap play. Sleep.
Made for 3am.
Most sleep apps assume you're using them in daylight — settings screens, bright onboarding, login walls. We started over. This app is shaped around the actual moment of use: you can't sleep, you reach for your phone, you don't want to be blinded.
Dark by default
Near-black background, low-saturation accents. No white flash when you open it before bed.
Auto-fade screen
After 8 seconds of no input, the screen fades to black. Long-press to wake.
Glanceable countdown
"23 : 47 remaining" — the thing you actually want to know at 3am, not the duration you set.
Big touch targets
Operable half-asleep, one-handed, in the dark. One central play surface, chunky color rows.
No data, no analytics
No account. No network calls. No third-party SDKs. The app cannot tell whether you ever opened it — because it isn't looking.
Free and open source
MIT licensed. Read the code, fork it, build your own. The whole app is a few hundred lines of Kotlin.
