Lumos overlays the paths of the sun and moon on your camera, your map, and your street — for any date, past or future. On the App Store since 2013, and now on Google Play.
Photographers plan golden hour. Gardeners find the sunniest bed. Home-buyers check a kitchen's morning light before the offer. Lumos does the astronomy; you make the call.
Point your camera at the sky and see the sun's full arc drawn on it — where it rose, where it stands, where it will set.
Sun and moon paths over any point on Earth, with solstice and equinox arcs to bracket the whole year at a glance.
Scout the light at places you can't visit yet. The same overlays, drawn on Street View imagery anywhere in the world.
Rise, set, phase, and position tables for any month — the numbers behind every view, ready to read.
How far a tree, wall, or building will throw its shadow at any hour of any day. Measure before you plant or build.
Alerts ahead of sunrise, sunset, and golden hour — so the light never catches you off guard.
A fully native Android app — built on the same astronomical engine as the iOS app, redrawn for Android from the ground up. Augmented reality, map and Street View overlays, the calendar, shadow lengths, and notifications, all on Google Play. Requires Android 10 or later. Thank you to everyone who tested the beta.
Questions, feature requests, or bug reports — every message is read by the developer.
