## What is Brightness Meter?

Is your bedroom dark enough to sleep well? Is your desk bright enough to focus? Brightness Meter turns your iPhone camera into a real-time lux light meter — no extra hardware needed.

Point your phone at any room and get an instant lux reading with clear, actionable guidance. Brightness Meter gives you the answer in seconds.

WHY LIGHT LEVELS MATTER
Light is the strongest signal your body clock gets. Too much light in the evening disrupts sleep; too little during the day hurts focus and mood. Most people have no idea how bright their rooms actually are — Brightness Meter makes it visible.

SMART LIGHT ZONES
Brightness Meter doesn't just show a number — it tells you what it means. Seven color-coded zones give instant context:
· Almost Dark — melatonin-friendly, ideal before bed
· Evening Ambience — relaxing, but too dim for reading
· Below Recommended — add light for focused work
· Good for Most Tasks — standard office lighting
· Well Lit — great for daytime, may disrupt sleep at night
· Bright — like an overcast sky, boosts alertness
· Outdoor — natural daylight

MADE FOR REAL LIFE
· Check your bedroom or your baby's nursery before sleep
· Optimize your home office or workspace lighting
· Get a quick estimate of light levels for houseplants and grow setups
· Compare rooms, corners, and times of day

SESSION TRACKING
Track minimum, average, and maximum readings as you move through a space. Reset anytime to start fresh.

PAY ONCE. THAT'S IT.
No subscription. No ads. No account. Buy it once and use it forever.

PRIVATE BY DESIGN
Brightness Meter uses your camera only to estimate light levels. No images or video are ever stored or leave your device.

DESIGNED FOR EVERYDAY USE
· Works with front and rear camera
· Calibration option for advanced users
· Battery-friendly — optimized at 4 frames per second

Brightness Meter is designed for personal use and awareness — not as a replacement for professional-grade instruments.
