Dawnline: Sleep Score

Most sleep apps hand you a number in the morning and leave you with it. Dawnline shows you where that number comes from — and how certain it is. Every number explains itself Tap any value and the arithmetic appears beneath it: the formula, the inputs it used, and the nights it rests on.
