Fitbit's Charge 5 is officially on sale, just in time for more Premium-exclusive content - Android Police

Available in black, gold, and blue — with a ton of optional band choices — the Charge 5 features seven days of battery life on a single charge, in addition to ECG and EDA sensors first seen on the company's high-end wearables.

It also uses the new "Daily Readiness" score to provide analysis and predictions on whether you're ready to crush your next workout.

At $180, it's a pretty expensive fitness tracker, though considering how blurry the line is between it and a full-on smartwatch like the Galaxy Watch4, it's certainly not unreasonable.
