So, which is righht for you?

Fitbit Charge 4 is obviously a better fitness tracking device. It has a larger display that allows you to see more at a glance, it has inbuilt GPS that means you can track your outdoor activities without having to carry your phone along. It also features an altimeter that enables it to count floors climbed, and there is SpO2 tracking that allows you to see your blood oxygen level when you sleep and wake up with the Charge 4. You can also control the Spotify playlist on your phone with Charge 4 – all of which Inspire 2 lacks.

However, Inspire 2 is still a decent fitness tracker. It’s a cheaper alternative, yet equipped to track your heart rate, sleep, steps, all-day calorie burn, and more. It also features preloaded sport modes and Active Zone Minutes which was introduced with Charge 4. Active Zone Minutes can be very helpful in helping you maintain a fitness goal. Moreover, Inspire 2 has a longer battery life than Charge 4, and with connected GPS to your phone, it allows you to track outdoor activities.

So, in conclusion, if you want more activity-tracking features, then Charge 4 is a better choice. Otherwise, Inspire 2 is a decent alternative if you’re tight on budget.
