Fitbit Charge HR vs Fitbit Surge

Last Updated on

The two top-of–the-range devices from Fitbit do both offer heart rate monitoring, as well as basic notification support. But what else do they come with? No need for further investigations we will show you the main differences between the Fitbit Charge HR vs Fitbit Surge.

The Fitbit Charge HR

Although the Fitbit Charge HR is very similar to the cheaper Fitbit Charge, it offers the advantage of an additional optical heart rate monitor located at the back. Added to this is a clasp with an extension on the strap that helps secure and lock the band onto your wrist.

Testers state that the band is very comfortable to wear, whether wearing it when sleeping, traveling or exercising.

As a precaution, it could be advisable to remove the Fitbit Charge HR when showering, as the device is not completely waterproof! With a stated battery charged life of 5 days, it’s not a big deal to spend a couple of hours on the charging process. See also Fitbit Charge HR replacement charger here.

The Fitbit Charge HR provides you with a crisp and clear OLED display and the convenience of a single button that is easy to press to advance and enhance the different views of your data.

The device is controlled and managed by your smartphone or desktop software, giving you the ability to select and view the clock, steps, distance, heart rate, calories, and levels on your Charge HR OLED display.

Being within the medium price range, the Fitbit Charge HR is a decent alternative to the more expensive Fitbit Surge. You can get the Charge HR in black and plum, but you may also want to check the availability of the device in navy blue and tangerine colors.

The Surge as, well as the Charge HR is enhanced with an optical heart rate sensor. Furthermore, the Surge does provide an additional GPS receiver to track your current position.

Both devices (Surge and Charge HR) have an integrated heart rate monitor

You will notice that the Fitbit Surge fitness tracker in sum is larger in size than any other previous Fitbit products. This is mainly because the display is larger and slightly raised off your wrist. The monochrome LCD display is very well readable indoors as well as outside, with a backlight for dark conditions.

With a touchscreen display that is responsive to your touch, an additional interaction is possible by two buttons on the right side of the device and a single button on the left.

Similar to the Charge HR, the Surge uses smartphone and desktop software. But, while the Charge HR displays caller ID information, the Fitbit Surge also provides you with text notifications.

Because you are able to read incoming text messages on your wrist, it will result in your phone being taken out of your pocket less often.

  1. Does either one work – really work – with Strava (app)? I track my bicycle rides with Strava but want to use a smartwatch as a heart rate monitor. Will either one work?
