What our users say
A must have for any photographer
Such a useful app for planning shoots! I use it to figure out where the light will hit, and it’s super accurate. The AR view is awesome, and it’s saved me plenty of guesswork when chasing golden hour. Simple, reliable, and a must have if you care about good light.
