That would be something, wouldn’t it? But unfortunately, we don’t offer that feature in Sleep Cycle right now.
However, if you got a funky night you want to remove from your journal and statistics, here’s how you do it -
Use the Journal to find the night you want to remove. Once found, scroll down to the bottom of the Journal. There’s a little thing there labeled “Delete this day” - which is rather odd, since it’s a _night_ you want to delete, not a day. Look, we’re devs first and foremost, linguistics second, okay? So there you are. Tap on this Delete label, and the night will be removed from your Journal.
