Lumora turns the ancient 24-hour solar clock into a live photographer's companion.
Unlike fixed 60-minute hours, temporal (solar) hours divide daylight and nighttime into 12 equal parts each — so hour length changes with the seasons and your latitude. Lumora calculates all 24 boundaries in real time from your exact location, giving you a living timeline of natural light from sunset to sunset.
FOR PHOTOGRAPHERS
Every solar hour is labeled with its photographic light phase:
⦁ Golden Hour (morning & evening) — warm, directional, portrait-perfect
⦁ Blue Hour (civil twilight) — cool ambient glow, cityscapes & seascapes
⦁ Nautical & Astronomical Twilight — astrophotography, Milky Way shots
⦁ Harsh Light & Peak Intensity — midday, high-contrast architecture
⦁ Soft Daylight & Crisp Daylight — product, food & lifestyle photography
⦁ Descent Light & Warm Daylight — second golden window before sunset
Tap any hour card to see the exact start/end times, photographer's phase name, and sunrise or sunset time if it falls in that hour.

SMART ALARMS
Set up to 5 custom alarms anchored to any solar hour:
⦁ Pick any of the 24 hours from a dropdown
⦁ Swipe to fine-tune: −20 to +20 minutes offset from the hour start
⦁ Daily or weekly recurrence (choose specific weekdays)
