Fitbit Charge 3 vs Inspire HR – Which One Is The Best?

fitbit charge 3 vs inspire hr

When you hear fitness tracker you think of a 21st-century invention, right? Wrong! Did you know that the very first fitness tracker can be traced as far back as the 1700s when they were more commonly known as a pedometer?

It’s a toss-up whether to credit horologist and inventor Abraham-Louis Perrelet for creating the earliest introductory pedometer or American Founding Father Thomas Jefferson who came up with a mechanical pedometer that was based on Perrelet’s original design.

What we know as fitness trackers really came on the scene in 1965. It was called the Manpo-kei, which translates from the Japanese to ‘10,000 steps meter. ’ This device was invented by Dr. Yoshiro Hatano, a Japanese professor at the Kyushu University of Health and Welfare, to help people dealing with issues relating to obesity.

Dr. Hatano concluded that having a healthy body requires a balanced combination of physical activity, that involves a minimum of 10,000 steps, and a well-balanced healthy diet. This number became the starting point for modern fitness trackers to gauge progress. However, the International Journal of Obesity published a recent study that suggests 15,000 steps may actually be the ideal minimum threshold to achieve optimal results.

The progress of technology in this area continued onwards and upwards when in the 1980s Polar watches incorporated wireless heart rate monitors. As mobile phones grew in popularity additional measuring features like 3D accelerometers (measures movement and the vibration in 3D space) were added with the upgraded Nokia’s 5500 Sports handset being the first phone to include an accurate physical activity tracker.

Fitness trackers began on the hip with a clip-on placed on the waistband and then later relocated to the wrist and this became the beginning of an entire line of what we nowadays call ‘wearables’ which includes health/fitness trackers, smartwatches, cameras, and VR headsets.

New inventions can be very exciting. It stimulates a demand for more and more until people become aware that more may not be necessarily better. With so many accouterments available, people find that the axiom “less is more” to be more apt and prefer simplicity as well as convenience.

Smartwatches have become quite popular as it offers a few devices integrated on your wrist. However, keeping the focus on the task at hand is also important to many. When going out to exercise a smartwatch with its many non-workout related functions operating may be distracting as well as unnecessary during a 30-60 minute workout.

For people who would prefer to keep it simple and want a fitness tracker for just that sole purpose, we are going to keep this review focused solely on fitness trackers with two models by Fitbit.

Fitbit, Inc. is an American Company that was founded on March 26, 2007, with headquarters located in San Francisco, CA. The company’s primary focus has been to develop and manufacture wearable fitness trackers that will measure and record health stats like heart rate, calorie burn, steps walked/run to support the avid fitness followers.

Fitbit’s first tracker was launched in September 2009 and was simply called Fitbit. A clip-on motion detector tracker solely used for tracking movement, sleep, and calorie burn 24/7. This device included its own wireless docking base that synced with the tracker. All updates were available via one’s computer (Mac or PC) and all the metrics information would be available to view from Fitbit’s online dashboard portal.

Subsequent models have come out offering either a more economical version with new features like an oxygen saturation (SPO2) sensor, an extended dashboard, option to log weight, water intake, as well as tracking exercise progress and goals.

Additional features that have come out in the past couple of years include running detector, enabling auto-pause and auto-stop, a birdie goal celebration as well as new clock faces to change up the device’s appearance to the user’s personal liking.

If you want to know if these trackers are reliable and accurate as advertised, you can check out studies that are available online. For example, a small 2015 study had participants wear Fitbit One and Flex trackers on the hip and wrists while walking or running on a treadmill.

Hip worn devices were found to be more accurate than their wrist-worn counterparts with a discrepancy of 10 steps between the two. When tracking calories burned, hip devices underestimated the tally by an average of 6%, wrist devices overestimated by 21%. The conclusion showed that hip devices were more accurate.

For quality trackers, Fitbit was runner-up at TechCrunch50 in 2008. At CES 2009, Fitbit was designated Innovation honoree and best in the Health & Wellness category.

In 2016, Fitbit ranked 37 out of 50 for most innovative companies and 46 on the Deloitte Fast 500 North America list.

If you want a waterproof wearable that offers only tracking functions and can receive notifications then you need not buy an expensive smartwatch. Instead, you may want to consider checking out a couple of Fitbit devices.

We are going to review and compare Fitbit’s Charge 3 and Inspire HR. They are both reasonably priced and have the basic features you are looking for to support your fitness goals. Both devices are smaller and sleeker compared to other devices which is always an attractive feature for many as it is more comfortable to wear on your wrist.
