The Huawei Band 10 gets it – some days are great, and some, not so much. The Emotional Wellbeing Assistant is there to keep an eye on your mood and offer helpful tips. You can even choose an adorable pet-themed watch face that reflects how you're feeling. Because sleep is super important, it measures your average heart rate variability (HRV) while you catch some ZZZs. You'll wake up to detailed insights into your sleeping patterns and get timely notifications if anything's off. It's designed to be comfy to wear all day and night too. The ultra-thin design weighs in at just 14 g, so you'll barely feel it on your wrist.
