At $249, the Fitbit Sense 2 is admittedly more than twice the cost of the $99 Amazfit Active 2. But the former is getting up there in age, which means, you can easily find it on sale.
Price and case shape aside, the two devices share a lot of traits and features. Both the Fitbit Sense 2 and Amazfit Active 2 are sleek, reasonably lightweight wearables with bright and responsive touchscreens, onboard GPS, physical buttons and loads of wellness and fitness tracking tech. You also get a small smattering of smart features on either, along with support for both iPhones and Android handsets.
