I must be out of step with the times as I'm surprised by the favorable comments about Night Shift.

For my eyes, the f.lux nighttime adjustment and configurability is great. at work, i use it during daytime hours as well, helps greatly with eye strain.

Night Shift is like an introduction of the concept to a mass audience, surely it has a positive benefit for the uninitiated but there's a lot missing for folks who rely on it. Android is much better with multiple applications available to control this.

I thought it would have been a good gesture for apple to buy f.lux and get the "market leader", and some built in goodwill, as opposed to just copying them, but I guess such is life when you are the largest corporation in the world.
