Although a little old, the Fitbit Inspire 2 remains a reliable budget-priced option. It’s lacking GPS and Fitbit Pay but it’s so lightweight you won’t notice you’re wearing it. And you’ll receive extensive stats via the Fitbit app, including a score to show how well you slept, your total sleep time and a breakdown of when you were in REM or light sleep. Upgrade to Fitbit Premium and you can view your sleeping heart rate too.
