Editor's Rating

Which Should You Buy?

All three members in the Inspire Series have about the same functions which is to track your daily activities and help stay connected to important information that matters most to when you receive a notification on your phone. Inspire 2 and Inspire HR are more complete in terms of features, these two feature preset sport modes and can connect to your phone GPS to allow you track outdoor activities such as locations and routes which can be viewed from the Fitbit app.

Furthermore, both Inspire HR and Inspire 2 have heart rate sensors which allow for continuous tracking of your heart rate, Inspire lacks a heart rate sensor. Inspire HR and Inspire 2 will also track your complete sleep cycle in four stages; deep, light, awake, and REM which is not possible with Inspire.

In other words, Inspire 2 and Inspire HR have more features than Inspire. Moreover, Inspire 2 has a longer battery life than Inspire HR and Inspire as it can last up to 10 days compared to 5 days with the other two.
