Candles are nice to use from time to time and I very much like the visual appeal created by their slight flicker, but they do set things on fire if tipped so they require constant attention. I'm amazed society made do with them as primary illumination up until the early 1900s. :-) The stories about the first electric streetlights and how everyone was blown away by their brightness are fascinating.
As for sleepyti.me, I don't think people's sleep cycles and sleep latencies are accurate enough to make the times it suggests very useful. Most of the sleep tracking devices offer adaptive alarms, which are better at accomplishing the same goal.
