Style and Display: Fitness trackers don't have to be purely functional. Many watch-style trackers come with interchangeable bands to suit different wardrobes and occasions. If you're looking for a fitness tracker that can double as a daily accessory, check that the display is easy to read and understand while you're exercising. Look for bright displays with clear graphics.Water Resistance: Trackers with a water-resistance rating of up to 50 meters (or 164 feet) are suitable for swimming pools. If you need a tracker suited for open-water activities like ocean swimming, surfing, or paddle boarding, look for a rating of up to 100 meters (or roughly 333 feet) of open water.Battery Life: Depending on the features used, many devices can last seven to ten days on a full charge. GPS, for example, tends to use a lot of battery power. Some devices can even last up to thirty days or more. When shopping, be sure to check the average battery life compared to what you plan to use the device for before purchasing.Compatibility: Many high-tech fitness trackers are smartphone-compatible, allowing you to receive text, call, and app notifications directly on your wrist.

The metrics you want to track are a personal choice, so consider what stats are important to your goals and progress when selecting a device.Price: Trackers that provide you with basic data, like sleep cycle tracking or the number of steps each day, are usually budget-friendly.
