Sleep better by dimming your iPhone and iPad like f.lux

f.lux is great software to reduce night time screen use affecting your sleep. Unfortunately it’s not possible to install on iOS unless you jail break your device.

iOS now comes with a wonderful built-in alternative hidden in the Accessibility settings to let you dim the screen past the normal range of the brightness control.

iOS 9: Settings > General > Accessibility > Zoom

1. Set zoom filter to low light
2. Set max zoom level down to 1.2
3. Switch zoom on (screen should dim and zoom in)
4. Double tap with 3 fingers and drag to set zoom to 1:1 (this is a bit tricky)
5. Go to Settings > General > Accessibility > Accessibility shortcut — set to Zoom

Now you can triple click the home button to switch screen dimming on and off.

iOS 8: is slightly more hidden — follow this video for instructions:

Android has some good clones of f.lux — I use Lux Auto Brightness.
