Additionally, the activity tracking offered, including active minutes and a built-in pedometer, meets the needs of users looking to monitor their daily physical activity. The Bluetooth 4.0 connectivity also ensures an efficient link with other compatible devices. However, several drawbacks are worth noting. The lack of a touchscreen limits interaction and user experience compared to other more advanced models. Furthermore, some advanced features, such as sleep quality tracking or stairs climbed, are not present, which may disappoint those seeking a more comprehensive analysis of their fitness. While the battery life is adequate, it may be insufficient for intensive users desiring continuous tracking. Finally, the absence of Wifi connectivity restricts certain functionalities and synchronization with other devices. In conclusion, the Fitbit Flex 2 is a solid choice for those looking for a stylish and functional connected bracelet.
