The Fitbit Inspire is the latest fitness tracker to join the rich list of Fitbit’s fitness-focused wearables, and the Inspire is available in two models; the Inspire HR and Inspire. The main difference between these two is that the Inspire HR going by its name has a heart rate sensor which the Inspire lacks. As a result, the Inspire HR has more activity tracking features than the Inspire which we have detailed below. In this guide, we take a look at the differences between these two to help make the right choice.

- DESIGN AND DISPLAY:
- ACTIVITY TRACKING:
Both the Inspire and Inspire HR have same appearance, and the design is the same except for the difference in available colors. Each of the two has a 1.4 inches display size powered by a monochrome OLED display. Both trackers also have a touch-sensitive screen.
The main difference between Inspire and Inspire HR comes in their respective activity tracking capabilities.
- While each of these two is equipped to track your daily activities such as steps, distance, active minutes, calories burned, automatic recognition for select sport modes, menstrual cycle logging via the Fitbit app, and sleep tracking, the Inspire lacks a heart rate sensor, and as a result, is unable to track your sleep stages and heart rate. The Inspire HR can track your sleep stages, it will track your heart rate 24/7 as well as track your heart rate zones and resting heart rate.
- Moreover, the Inspire HR will give you a fitness score based on your fitness level.
- Furthermore, while each of these two lacks a built-in GPS, only the Inspire HR can track your routes and locations when you carry your phone along. In other words, Fitbit Inspire lacks connected GPS functionality.
- The Inspire HR features a breathing app that can guide you through a breathing session when you’re stressed. There is no breathing app on the Fitbit Inspire.
- The Inspire HR also features a sedentary reminder that reminds you to move when you sit idle for too long. This isn’t present on the Fitbit Inspire.
- Moreover, with the Inspire HR, you get 15 preloaded workout modes to choose from which are not present on the Fitbit Inspire.
VERDICT: Although these two are great choices for keeping tab on your fitness goals, the Inspire HR being more equipped with a heart rate sensor is a more comprehensive activity tracker and is clearly a better choice.
