Chase the Light is the essential tool for cinematographers, photographers, and anyone who lives for the magic of natural light.
Know exactly when golden hour begins where you're standing. Every time is calculated for your GPS coordinates and today's date, and live weather tells you what the light will actually look like.
THE LIGHT LOOP — YOUR DAY'S LIGHT AT A GLANCE
A 24-hour loop on the home screen shows where you are in the day, from soft daylight through golden hour, blue hour and night. As golden or blue hour approaches, it opens up with a live countdown to the next phase. The rest of the day it folds into a compact capsule, out of your way. Tap any phase to see when it starts today, what the light looks like, and how to shoot it.
SEVEN PHASES OF LIGHT — PRECISELY TIMED
Every cinematographer knows the best light lasts only minutes. Chase the Light times every phase of the day for your exact location and date:
- Night — Full darkness. Stars and long exposures.
- Astronomical Twilight — The sky begins to glow. Deep navy hues emerge.
- Nautical Twilight — Rich indigo and violet tones. The horizon comes alive.
- Blue Hour — Cool ethereal blue light. No shadows. Pure atmosphere. Also known as civil twilight.
- Golden Hour — Warm, soft, directional light. The magic begins.
- Low Sun — Warm, angled light. Long dramatic shadows.
- Soft Light — Gentle daylight. Flattering and cinematic.
LIVE ACTIVITY — THE COUNTDOWN ON YOUR LOCK SCREEN
Open the app around golden or blue hour and follow the countdown on your Lock Screen and in the Dynamic Island, phase by phase, without unlocking your phone. With Pro alerts on, it starts on its own.
