Layer ambient sounds for better sleep, focus & calm
Rain alone is too much. White noise alone is too harsh. People need to blend and balance.
Most sleep apps are adult-focused. Parents need a safe, simple, child-appropriate interface.
SleepMixBlueprint lets you layer multiple ambient sounds simultaneously, control each track's volume independently, and set a gentle fade-out sleep timer — all in one calm, distraction-free app.
Layer multiple sounds at once with per-track volume sliders for a fully custom blend.
Set a duration and audio fades out gently — no jarring cut-offs mid-sleep.
Import any audio from your device. Files persist across updates and reinstalls.
Music keeps playing when the screen locks or a call comes in — on real devices.
All audio files are sourced from the app creator's own collection — no AI-generated or licensed content, no redistribution concerns.
Home screen. Layer built-in + imported sounds. Set timers. Full-volume control per track.
Import, tag and manage your own audio files. Re-import warnings if files move or are deleted.
Pomodoro-style 25/5 work-break cycle with focus-optimised audio.
Simplified parent interface, violet accent, short timer presets (15–45 min).
Real-device reliability was the north star. Every feature was shipped with a matching fix for the edge case that breaks it in production.
"A cross-platform mobile app that solves a real problem — shipped end-to-end, from concept to TestFlight."
