Never miss the perfect light.

SunMoon Alert: Light Planner is a photo and video planner for photographers, filmmakers, creators, and outdoor users who want better timing, better light, and better results.

Light changes every day with time, season, and location. The best moment for a portrait, skyline, landscape, selfie video, or moon shot never stays the same for long. SunMoon Alert helps you spot the right moment before it happens, in clear skies and with an unobstructed view, so you can be there on time.

Use it to plan golden hour, blue hour, shoot windows, moon phases, sun angle, sunrise, sunset, twilight, moonrise, and moonset. Then set smart alerts so you are ready before the light changes.

What you can do with SunMoon Alert
• Plan golden hour and blue hour for photography and film
• See today’s light windows from blue hour to high-contrast daylight
• Find shoot windows for portraits, landscapes, architecture, macro, street, food, and more
• Check the sun angle and use a sun angle calculator
• Create alerts and timers for sun, moon, and photo style moments, including your preferred sun angle.
• Track moon phases, moonrise, moonset, and moon altitude
• See upcoming full moons, new moons, and eclipses

SunMoon Alert is more than a basic sunrise and sunset app. It combines light planning, moon planning, alerts, and shoot timing in one workflow. Instead of switching between a golden hour calculator, moon phase calendar, and separate alert apps, you get everything in one place.

Also useful beyond photography
SunMoon Alert can also support travel, gardening, sports, and daily outdoor planning. It includes tropical and sidereal zodiac references for the Sun and Moon and supports moon-based planning such as ascending and descending moon rhythms.

If you often ask:
• When is golden hour or blue hour?
• When will the moon rise or set?
• What light is best for portraits, landscapes, street, or video?
• What will the sun angle be at a certain time?

SunMoon Alert helps you answer these questions clearly and fast.

Works worldwide and fully offline for all core features, with no account and no ads.

The free version allows one alarm per day.

Whether you plan portraits, landscapes, moon photos, or video shoots, SunMoon Alert helps you arrive at the right time for the right light.
