Features
Read full description

Naptx is a modern white-noise and nature-sound studio crafted to ease you into sleep, deep focus, or mindful relaxation. Pick a profile from the animated grid, watch the audio-synced wave breathe with your sound, and drift into a calm atmosphere with one tap. - 9 immersive sound layers: white/pink/brown noise, rain, ocean, forest, thunder, water droplets, and wind. - Living interface: morphing play button, floating particles, and an audio-sync pulse keep the screen feeling alive. - Precise control: silky volume slider with live percentage readout, plus an optional high-resolution audio engine. - Sleep timer done right: quick 15/30/60 min presets, extended 45 min & 2 h options, status panel with countdown, and auto-stop when time’s up. - Smart start: auto-play your favorite sound the moment the app opens, set your default profile, and lock the theme (system/light/dark). - Offline freedom: every sound is generated on-device, so your routine works in airplane mode and can mix with other media apps. - Night routine: set the timer, start your sound, and dim the screen. - Deep work: mask distractions with white or pink noise and fire up Auto-Start for instant focus. - Meditation & relaxation: layer ocean or forest ambiences with the pulse animation as your breathing cue.
