Lumy

Lumy is the perfect companion for anyone who wants to track sunlight and plan their outdoor activities.
- Perfect lighting for photos or videos? Done.
- Sunrise hike or sunset walk? Easy.

Whether you’re chasing golden hour*, planning your daily dose of Vitamin D, or tracking moon phases for stargazing, Lumy helps you make the most of natural light.
Now redesigned from the ground up - Lumy feels more personal, purposeful, and in sync with how we live. Inspired by sunlight filtering through a window, every view carries a subtle visual echo of light seeping through a pane of glass window.
Introducing Modes: Switch between profiles like Daily, Photography, or Meditation to shape Lumy around your routine. See only what matters to you.
Lumy also supports iOS 18’s State of Mind feature, offering sunlight suggestions based on your mood entries in the Health app - a gentle nudge to step out and connect with nature.
And with weather forecasts for the next seven days, you can plan ahead with confidence. Lumy calculates all sun and moon data entirely on-device. No tracking. No server calls. Only weather needs internet.
