Common questions
How accurate is this thing?
It's based on the 90-minute sleep cycle, which is a well-established average. That said, your cycles might be slightly shorter or longer. Think of the results as a solid starting point. Try the suggested times for a week and adjust from there.
Is this medical advice?
No. We're three people who read a lot of sleep research, not doctors. If you're dealing with persistent sleep problems, see a real healthcare provider. A calculator on the internet is not a substitute for that.
I have a feature idea
Send it over to contact [at] sleepcalculator [dot] com. We actually read every email. Can't promise we'll build everything, but good ideas tend to make it onto the list.
