An app that filters out your phone's harsh blue light to reduce eye strain and help you sleep better.
Blue light from your phone's screen can inhibit your production of melatonin, the hormone that tells our brains it's time for bed. If you regularly use your phone before bed, Twilight can offer a simple way to better prepare you for sleep.
