Where are the differences?

Let's have a closer look by comparing the differences between the two Wearable Charge 4 Special Edition and Inspire made by Fitbit.

Release Date

Both products were made in two consecutive years. The Fitbit Charge 4 Special Edition was first released in 2020. Consequently, the Fitbit Inspire from 2019 is older.

Display

You'll get a display with both devices. Here, both Wearable have an integrated color display. In both cases, there is a touch display. The display technology is the same with both devices, and have a OLED display. The display of The Fitbit Charge 4 Special Edition sports 1,56 " and is smaller than the Inspire. Here, the diameter is 1,58 ". None of the two devices have an always-on display function.

Waterproof

Both, the Charge 4 Special Edition, as well as the Inspire are waterproof, and have no further difference in this feature. Both Wearable can be used under water in depths of up to 50 m. The Fitbit Charge 4 Special Edition can even track and record your swimming lanes.

Battery

The Fitbit Charge 4 Special Edition sports a longer battery runtime with 7 days. the Fitbit Inspire battery lasts merely for 5 days. Both devices take 2,0 hours to be fully charged.

GPS

An integrated GPS of the Wearable is in this case only available with the Fitbit Charge 4 Special Edition.

Heart Rate Monitor

A fitness watch without a heart rate monitor is basically useless and not advisable to buy. That's because your heart rate is one of the key elements of different calculations. For example, many devices without a heart rate monitor claim to count your calories burned too. That number will hardly be right without having access to your heart rate.

Comparing the Fitbit Charge 4 Special Edition and the Fitbit Inspire, both devices offer the heart rate monitor function and score in our books. On top of that, both will monitor your heart rate 24/7. Some devices only do that when you press a button, which is practically speaking rather useless.

Measured values

Only the Charge 4 Special Edition can track how many floors you've covered.

the Charge 4 Special Edition can record your sleep.

Bracelet

Being able to change your fitness watch band is a great advantage. You'll only have to worry about the color of the device itself, and not the color or material of its accompanying watch band. For pretty much every device, you can get cheap watch bands that will fit your device. You can make use of this advantage with both devices of this comparison.

Smarct functions

Getting call, text, or other notifications is a feature that both tools have. Often times, this feature is only possible with an Android device. iOS user can be left behind on this. Sending QuickReplies is not an option for either one of the two devices.

The interface, or the dial of your watch, can be changed with both, the Fitbit Charge 4 Special Edition , and the Fitbit Inspire.

Contactless payment

Contactless payment is a highly useful and more in demand than ever technology. Many Wearable already offer it. Being able to do this from your wrist is even more convenient than using your smartphone or a credit card. There's a difference here between the two devices, as only the Fitbit Charge 4 Special Edition hooks you up with contactless payment technology. With the Charge 4 Special Edition, Fitbit Pay is being used.
