When do new facts arrive?
Every evening at 20:00 your local time. Until then you see the previous evening’s facts.
My reminder doesn’t appear
Open BedtimeKnowledge → Settings and check that the daily reminder is on. Then check iPhone Settings → Notifications → BedtimeKnowledge → Allow Notifications. Focus modes (Sleep, Do Not Disturb) can also hide it.
Why doesn’t my quiz count for my streak?
Only quizzes played on the evening of their issue count, so everyone’s streak means the same thing.
