I’ve been recording my sleep for the last few months using Autosleep. Whilst I’m sure I’m actually improving my health and getting a better nights sleep it’s also an odd thing to watch the sleep credit percentage change. I think it’s impossible to not earn sleep credit at the weekend and spend over the course of the working week. Any random late night hits your sleep credit as hard as any large financial bill hitting your checking account. Just like in financial terms, surely the purpose of gaining credit is to spend it.
