Lightphase
A light clock for photographers. Lightphase names the phase of natural light you're standing in (twilight, golden hour, the 35° window) and counts down to the next one. Drag the sun along its curve to see what the light will be doing later, or glance at a widget or Apple Watch complication instead of opening the app. The sun is computed on the device, so it works with no signal and your location never leaves your phone.
