If you're in the market for a wearable that'll track your daily activity and help you lead a healthier life, the Charge 4 and Inspire HR are both well-equipped in these regards. Both fitness bands count your steps, calories burned, stairs climbed, distance, and more. Each tracks a variety of different workouts and comes outfitted with a heart-rate monitor that'll keep tabs on your ticker all-day long.

Both the Charge 4 and Inspire HR have an excellent foundation for basic fitness tracking.

The Charge 4 and Inspire HR also share the same outstanding battery life that's rated for up to seven days on a single charge and can track your sleep if you wear either one throughout the night.

Where the Charge 4 gets the upper-hand is with more minute health features. With this tracker, you can receive real-time GPS and pace-tracking without a smartphone on you, while it also supports a broader range of activities and workouts.

The Charge 4 also gets an edge when it comes to non-fitness features. Although the Inspire HR can show basic call, text, and calendar appointment notifications from your phone, that's about it. The Charge 4, on the other hand, retrieves any notification your phone gets and even allows you to send off quick replies to texts, WhatsApp messages, etc.

Also, while the app selection for the Charge 4 isn't anywhere close to what you'll find on something like the Apple Watch, it does have basic apps for checking the weather, your calendar, set an alarm or timer, and more. Lastly, the combined power of built-in GPS and Fitbit Pay make this a really complete fitness tracker.
