Smart night light app designed for quality sleep and a cozy nighttime environment. Whether it's gentle care for a nursery or a moment of relaxation for adults before bed, Wonder Light makes every night just right. --- **Core Features** **White Noise** A curated collection of natural and environmental white noises, including ocean waves, rain, forest breeze, campfire, stream, fan, and more — all with clear, natural sound quality. Supports looping, playlist switching, and scheduled shutdown. Whether you need to block out city traffic, neighbor noise, or help your baby fall asleep, Wonder Light creates a quiet and soothing auditory environment. **Deep Sleep AI Lights-Out** Powered by an intelligent sleep sensing algorithm, the app learns your sleep rhythm. When it detects that you have entered light or deep sleep, the light will automatically dim at an extremely slow pace and eventually turn off completely at the right moment. The entire process is gentle and undisturbed, preventing sudden darkness from startling you awake and eliminating overnight brightness that interferes with melatonin production — helping you sleep deeper, more steadily, and more peacefully. **Color Wheel Palette** Freely slide across a full-spectrum color wheel with fine brightness adjustment from 0 to 100. Choose from tens of thousands of colors — from warm cozy yellow to calm cool blue, from soft pink to deep starry purple. Whether it's late-night reading, nighttime nursing, a romantic dinner, meditation, or creating a safe and warm glow for a child's room, there's always a color to match your mood and needs. **Multi-Scene Themes** Switch between carefully preset scene themes with one tap. Each theme links light color, brightness, and a recommended white noise, for example: - Reading Mode: Bright warm light with gentle page-turning ambiance - Bedtime Mode: Gradually dimming warm yellow light with soft rain sounds - Starry Night: Deep quiet blue light with distant wind and insect chirps - Wake-Up Mode: Simulated sunrise warm light, gradually brightening to wake you gently - Campfire Night: Warm orange flickering effect with crackling firewood sounds You can also customize and save your own scenes for easy recall anytime. **Child Lock** When activated, Child Lock disables touchscreen operation and settings to prevent little hands from accidentally changing lights, switching sounds, or exiting the app. Basic on/off control remains accessible, giving parents peace of mind to place their phone or iPad next to their child's bed. Child Lock is also useful for adults who want to avoid accidental touches during sleep. One tap to turn it on, one tap to turn it off — simple and practical. --- **More Highlights** - Supports background playback — white noise continues even when the screen is locked or other apps are in use - Scheduled shutdown option to avoid playing all night - Clean and intuitive interface — all functions accessible with one hand - Optimized for iPhone and iPad, perfect display in both portrait and landscape orientations --- **Use Cases** - Unwind before bed and relieve the day's fatigue - Nighttime nursery care and soothing babies to sleep - Protect your eyes while reading or working late - Meditation, yoga, or deep breathing exercises --- **Subscription Service** When you subscribe to the "VIP Subscription" service, you will enjoy the following benefits: 1. Unrestricted access to all features. 2. AI content recommendations based on usage habits. Payment for subscriptions is straightforward—the user's iTunes account is credited immediately after confirmation of purchase and payment.

Simple Night Light

A softer light for the middle of the night. When your iPhone flashlight is more than you need, Night Light turns your screen into a calm, gentle light. Open the app and your saved color and brightness are ready. No account, setup, or clutter. MAKE IT YOURS Choose warm amber, warm white, deep red, candle, green, or moonlight. Pick any custom color and adjust the screen brightness from 1% to 50%. Night Light remembers your favorite settings for next time. Deep red and warm amber are gentle choices for checking on a sleeping child or finding your way without waking anyone. OPEN IT YOUR WAY Add the circular widget to your Lock Screen or Home Screen to open your saved light with one tap. On iOS 18 and later, you can also add Night Light to Control Center, a Lock Screen control, or the Action button on supported iPhones. Normal iPhone authentication may still be required. OPTIONAL REAR LIGHT Need a little more? One tap turns on the rear flashlight at a deliberately low level. It never turns on automatically, and it switches off when Night Light leaves the foreground. SIMPLE BY DESIGN Night Light opens directly into your favorite preset, uses a dark launch screen, and keeps controls minimal and easy to find. FREE AND PRIVATE Night Light is completely free, with no ads, accounts, subscriptions, analytics, or tracking. Your settings remain on your device. Optional tips unlock nothing—the full app is available to everyone.
