Onboard is a heart rate tracker with high and low heart rate alerts an electrocardiogram app that detects signs of atrial fibrillation an SpO2 sensor for blood oxygen levels plus skin temperature tracking at night (but no dedicated skin temperature sensor like on the Sense). Heart-rate alerts, ECG and all the health metrics you could wantĮven though the Charge 5 is significantly smaller than Fitbit's smartwatches, it doesn't skimp on sensors. Most importantly, the text is legible and large enough so I never feel like I am squinting to see notifications, or reaching for a magnifying glass like on the Fitbit Luxe. And the interface is actually pretty responsive, which is a welcome change from some earlier Fitbit trackers. It might take a few tries to learn, but just having come off the back of reviewing the Fitbit Luxe, the Charge 5 is a lot easier to use because of its bigger screen. Navigate by swiping and tapping on the screen, then swipe right or double-tap anywhere to go back to the previous screen or clock face. This is also the first Charge to have no buttons whatsoever. It doesn't show up well in this image, but the Charge 5 screen is easy to read outdoors. You get the option to leave the display always on, so that means no need to raise your wrist to see the time. It's also way easier to see outdoors when the brightness is set to max. The screen offers an immediate advantage over the Charge 4, which had a monochrome display. The Charge 5 is comfortable to wear 24/7įitbit's given the Charge 5 a significant facelift from older models, adding a color AMOLED touchscreen and a new navigation system that's pretty much the same idea as Fitbit's recent slimmer tracker, Luxe, but larger. I'll need to spend more time with the score before I can make a call on how useful it really is, but in the meantime, there's enough here to wholeheartedly recommend the Charge 5 if you want a tracker with built-in GPS, an ECG, robust sleep and fitness tracking and strong battery life.

This score is rolling out now to a range of Fitbit trackers and watches, including the Charge 5, but you'll only be able to see it alongside personalized recommendations with a Fitbit Premium subscription. The Fitbit app will tell you if you're ready to workout with personalized activity goals, or take it slow with meditation sessions based on your metrics. What does it mean if my heart-rate variability is high? Should I try to push myself to work out if I had a really bad night'sįitbit is on the precipice of being able to solve this mystery, maybe, with something called a Daily Readiness Score. Fitness trackers and smartwatches have offered us a wealth of data gathered from our wrists for years, but being able to interpret it is kind of a puzzle for most people. Fitbit Premium subscription needed for in-depth health metricsīut there's still one piece missing.
