The Fitbit Charge 5 is a high-end fitness tracker with a stunning lookingAMOLED display. It’s a little on the small side, but that makes it a comfortable fit when you’re snoozing: no need to worry about it getting in the way. The Fitbit ecosystem is well designed for detailed sleep analysis, right down to its monthly sleep profile tool. It’s not cheap – but it also measures stress, offers ECGs, and tracks fitness to boot.
