Bluelight filter for eye care has a function like that, for some inspiration �� I don't remember which method it uses though..
Hey, I know it's been a while, but I've finally updated the app! You can schedule it to turn on at sunset, and off at sunrise now ��

Hey, thanks for your feedback! I'm not sure if I've already notified you through the play store, but I've added this feature in the latest update: 3.3.0
Please take a look! ��
