Noxtra turns your iPhone or iPad into a clean, monochrome light radiator that stays awake while the app is open. Use it as a night lamp, a gentle bedside glow, or a quick, low-distraction light source when getting up at night.

Noxtra is also a practical accessory for close-up and macro photography. Add a subtle hue to a scene, shape highlights on reflective surfaces, and use your device as a compact lighting tool in a larger creative setup. For makers, designers, and builders, Noxtra also works as a live color reference. Tune hue, chroma, brightness, and alpha visually, then copy the current HTML hex or RGBA value with a tap. Press and hold to edit exact values directly. Features: - Full-screen calming light with hue, chroma, and brightness controls - Adjustable alpha for softer layered light output - Screen stays awake while the app is active on iPhone and iPad - Fast single-tap show and hide for controls - Double-tap toggle between brightness and chroma adjustment - One-tap copy for HTML hex and RGBA color values - Press-and-hold editing for exact `#HEX`, `RGBA`, and alpha values - Clean interface built for focus, speed, and low distraction Whether you want a gentle evening light, a portable color tool, or a subtle photographic accent, Noxtra keeps it simple and ready in an instant.
