Fitbit Inspire and Inspire HR were released last year, the main difference between these two is that Inspire HR can connect to your phone GPS to enable tracking for outdoor activities which aren’t possible with Inspire. Inspire HR also has heart rate tracking and tracks your sleep stages as well as other metrics that Inspire lacks. This year, Fitbit has announced a follow up in Inspire 2 which unfortunately still lacks inbuilt GPS, but has a longer battery life and features Active Zone Minutes. In this post, I take a look at the differences between the three Fitbit trackers, Inspire vs Inspire HR vs Inspire 2.

I’m currently using the Fitbit Inspire and I really like it! The only downside is that it doesn’t track sleep well, but other than that it’s been great. I’m looking forward to trying out the Inspire 2
Nice to hear that, but if I were you, I would go for the Inspire 3. It’s the almost same price as Inspire 2 but has a colored display with an always-on and ambient light sensor. It can also monitor blood oxygen.

That’s not nice, I believe the Inspire 2 will do a better job at sleep tracking. I have used the Versa 2 and 3 and both did pretty fine tracking my sleep.
