Read our full Fitbit Charge 5 review and you can read our interview with Fitbit co-founder Eric Friedman here.

The Fitbit Charge 5 also won the title of the best fitness tracker in our Tom's Guide Fitness awards, as it looks cool enough on the wrist that you don’t mind wearing it all day long, and has a bunch of brilliant tracking capabilities. Also, if you're using a Fitbit Charge 3 or older, the upgrade is worth it for the color screen alone. If you want to save money, the Fitbit Charge 4 was the best fitness tracker before the Charge 5 was released, and is likely to be on sale. If you're looking for a tracker that looks beautiful against your wrist, is easy to read in the bright sunlight and has some impressive features for the price tag, this is a good buy. The Fitbit Charge 5 also has Fitbit's 'Daily Readiness Score' feature, which gives you an idea of how ready you are for a big workout, based on three different metrics - fitness fatigue (activity), heart rate variability (HRV), and recent sleep.
