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.
