F.lux for Mac Adds a “reverse Alarm” to Show You How Much Sleep You Are Missing
Mac: F.lux is a great app for changing the temperature of your display when you’re working late at night , but working late at night also means you’re skipping sleep. The Mac version of the app now has a new Reverse Alarm that counts down until the alarm goes off.
The new feature essentially just tells you how much sleep you will get if you go to bed at any time. It’s a small thing, but given that most of us only use F.lux when we’re working late, it’s really helpful. Apart from this, the Mac version also gets a new option for slightly dimming the screen when F.lux is turned off, improved transitions and additional daytime settings.
