Any way to put a specific time for it to turn on?
Can i set it at like 2 am to turn on?
Not in this version, but I think we will be able to in the next version, but there's no way to know when they will be done making it.
You can fake your location in f.lux though to a place where the sunrise time is 2am.
We'll have more customizable settings coming up in the future. Generally people need more darkness than sleep duration, so our goal is to bring the brightness down earlier and still let you use technology.
