Quick start guide Quick start guide
  1. Design
  2. Both Inspire HR and Charge 4 spot a decent design that is lightweight, sleek, and comfortable to wear. Greyscale OLED powers the display on both devices which can be easily read. The body of both devices is also made with the plastic material while the straps are made from elastomer. Each of these two is also rated 5ATM which means waterproof up to 50 meters. Thus, it’s safe to wear any of these two to the shower or pool. In other words, I can say the design of both devices look good.

  3. Fitness Tracking
  4. Fitness tracking is where both devices differ even though similarities are more. Both Charge 4 and Inspire HR will track your steps, distance, sleep in three stages: (REM, deep and light), continuous heart rate, stress management through guided breathing session, menstrual cycle tracking with 20 preloaded sport modes.

    The difference though is the presence of inbuilt GPS in Charge 4 which Inspire HR lacks. Thus, with Charge 4, you can track outdoor activities without your phone, but you’ll need to carry your phone along if you’re to map your run with Inspire HR. You can then see a map of your run from the Fitbit App.

    Another feature present in Charge 4 is Active minutes which allows you to set a target heart rate and the device will alert you when the preset target is reached. The Charge 4 will also count floors climbed, a feature Inspire HR lacks.

    The bottom line, Charge 4 is a more comprehensive fitness tracker.

  5. Battery Life
  6. Fitbit Charge 4 has a longer battery life than Inspire HR. Users claimed that Charge 4 lasted an average of 5-6 days as against 4 days of Inspire HR. Please note that the actual battery life will vary by users.

  7. Smart Features

There are also some smart features present on Charge 4 which Inspire HR lacks. Although, each of these two will alert you when you receive a notification on your phone, but Charge 4 features the sleep mode that allows you mute notification while sleeping and do not disturb mode that allows you to mute notification during the day. Charge 4 also comes NFC that enables Fitbit Pay, a feature that allows you to make a payment from the device.

Which Should You Buy?

The bottom line, Charge 4 is better than Inspire HR. It has more fitness tracking and smart features and as a result, you’ll have to pay more for it.

However, Inspire HR is still a great choice. The only difference is that you’ll have to carry your phone along when tracking outdoor activities, it can’t count floors you climb and there’s no NFC, yet I think it’s still a wise investment for the price.
