Smart Fill Light for iPhone

Turn your iPhone into a professional softbox. Transform your screen into a powerful, colour-accurate light for makeup, video calls, content creation, photography, and any moment you need just-right lighting.

— Beautiful Light, In Your Pocket Edge-to-edge, flicker-free illumination with smooth dimming. Adjust brightness and colour temperature from warm tungsten through neutral white to cool daylight, all from a single screen. No clip-on rings, no batteries to charge — just open the app.

— Tap-to-Apply Presets and Colour Gels Studio-style presets cover the most common looks: soft daylight, golden hour, cool white, tungsten warm, magic-hour orange, and more. The built-in gel library adds creative tints — magenta, teal, amber, lavender, ice, fire — for music videos, mood shots, and stylised portraits. Save your own combinations and recall them with a tap.

— Sample the Light Around You Point the camera at the room. In about two seconds the app reads the ambient light and matches your screen, so the fill blends with the space instead of fighting it. No photos or video are captured or stored.

— Mirror Mode A built-in selfie mirror with adjustable lighting on top. Apply makeup, fix your hair, line up a shot, or check your look in any light.

— Pro Tools - Animation Modes — gentle cycling colours for vibe lighting - Strobe — adjustable speed for video and effects - Split Zones — multi-colour regions on a single screen - Hex Input — type any colour you want, exactly - Session Timer — auto-dim after a set duration

— Immersive Light Mode A distraction-free full-screen mode. Drag up and down to fine-tune brightness, drag side to side for colour temperature. The UI gets out of the way so you can focus on the light.

— Hands-Free with Siri Shortcuts - "Daylight mode" - "Tungsten mode" - "Cool white mode" - "Open Light"

— Designed for iPhone Smooth output on ProMotion displays. Edge-to-edge brightness with no banding. Battery-conscious. Tuned for portrait orientation.

— Premium Unlock the full preset library, colour gels, Mirror Mode, ambient sampling, and the pro tool set with a one-time premium upgrade. No ads. Ever.

Light up your moment.
