FITBIT VERSA 3

£199.99 + £7.99 per month subscription, fitbit.com

Fitbit recently jumped on the readiness bandwagon, adding a daily score to its Versa 3, Versa 2, Sense, Charge 5, Luxe and Inspire 2 trackers. It compares your recent activity, sleep and HRV levels against your personal baseline, with easy-to-monitor day and week views of your scores out of 100. That’s along with personalised activity targets and workout recommendations based on your results.

Like Garmin, this relies heavily on the accuracy of the optical heart rate sensor. Unlike Garmin, the insights are frustratingly locked behind Fitbit’s Premium subscriber paywall, and access will cost you £7.99 a month.
