What it is
Lightphase is a light clock for photographers. It answers two questions and nothing else: what phase of natural light you are in right now, and when it changes. Six thresholds of the sun’s angle divide the day into named bands, from Astronomical Twilight through Golden Hour to the flat light overhead, and the app reads the one you are standing in and counts down to the next. There is no account, no server and no solar API. The sun is computed on the device from your coordinates and the time, so it works in airplane mode, in a canyon and on a ridge, and your location never leaves the device.
