To start using Daily Readiness, you'll need to make sure you keep your tracker on for at least four full days - including while you're sleeping. It was easily the thing I was most excited to try out when I got my hands on the Charge 5, although I'm left feeling pretty mixed about how useful it actually is. It's designed to maximize your ability to balance working out and resting, combining your previous workout data with sleep ratings and heart rate data to deliver a new prediction every single day. Since my initial review of the Charge 5 went live, Fitbit finally launched the marquee feature of its newest wearable: Daily Readiness.

If I needed to stop and buy something on a run, I'd either need my wallet or my smartphone in hand. Fitbit Pay seemed promising, but the lineup of supported banks is much smaller than Google Pay's, and neither of my accounts were supported. If you're looking to listen to tracks without a phone while working out, you'll need to sign up for Deezer or Pandora Radio - neither of which are particularly tempting in 2021. Despite sharing a parent company, YouTube Music isn't supported for offline playback here, and neither is Spotify or Apple Music. Outside of the tracking, I found the Charge 5 notably lacking in features compared to smartwatches. It wasn't ready for primetime at launch, but you can check out all of my thoughts on it in the update at the bottom of this review. It sounds pretty cool, combining your activities from the previous day with sleep data to predict the results of your next workout. Fitbit's newest addition for the Charge 5 is a 'Daily Readiness' score, designed to keep you focused on mixing workouts with rest days.
