Serenity - White Noise Garden のアプリ分析 12月9日

Serenity is your pocket sanctuary, designed for anyone who craves a calm mind, deeper sleep, sharper focus, or a gentle buffer against a noisy world. Powered by a studio-grade sound engine, the app streams endlessly looped layers of white, pink, and brown noise—scientifically tuned broadband frequencies proven to mask distractions, lull anxious thoughts, and train the brain to settle into productive flow or restorative rest. Pure Physics-Based Generation Unlike static MP3 loops, Serenity synthesizes noise in real time using 32-bit floating-point algorithms. The result is butter-smooth spectra free of clicks, gaps, or repeating patterns that the brain can latch onto. Choose classic flat white noise for a brisk, bright shush; mellow pink noise when you need balance between bass and hiss; or cozy brown noise that wraps you in warm low-end rumble—-all sourced from the same precision engine so their timbre blends perfectly. Adaptive Scene Mixer Stack multiple noise colors together or weave in subtle nature beds—ocean murmurs, steady rain, crackling fire—each with independent volume and stereo pan. Save unlimited scenes like "Deep Work," "Power Nap," or "Airplane Bubble" and jump back with a tap. Smart Sleep Timer + Fade Fall asleep without worrying about battery drain. Set a countdown, schedule a stop time, or let the auto-detect algorithm fade out once your microphone senses you've entered slow, steady breathing. Offline First Download any combination of noise layers for zero-lag playback on planes, subways, or back-country cabins. Tiny file sizes (‹ 5 MB each) mean you can cache a whole library while barely touching storage. HealthKit & Focus Filters Log sessions to Apple Health mindfulness minutes and sync with Shortcuts to trigger your favorite wind-down automation. iOS Focus modes dim notifications while Serenity is active so your calm stays undisturbed. Ultra-Low Power With a custom audio buffer routine tuned for 5× fewer wakeups per minute, streaming for eight full hours consumes less than 5 % battery on modern devices. Tap the OLED Night Clock to dim UI to true black and watch battery impact drop even further. Accessibility Built-In VoiceOver pronunciations for every control, dynamic type support, haptic feedback cues, and color-blind-safe palettes mean anyone can build a sound cocoon with confidence.
