Over the year I’ve been struggling with insomnia, this has worked better than melatonin tablets or other apps (both alternatives that work, but not as well). The color settings are customizable enough to fit many different preferences, which is definitely a good thing. However, my one complaint is that the sounds, which are sometimes more important than the colors, aren’t free, and most of the free options aren’t as effective. Maybe you could have the user pick three or four different ones for free when you first download NightLightLiteNightlight , so that they have sounds that are more likely to help them sleep, and they can buy the rest if they want? Besides that small complaint, NightLightLiteNightlight works really well. Would and have recommended!
