Fitbit Inspire 2: Our Best Pick

Fitbit Inspire 2

Fitbit is famously known for its reliable and accurate fitness trackers. Currently, the Fitbit Inspire 2 is one of the more recent devices to hit the market in 2020 (August, to be exact). It’s an entry-level tracker, meaning it’s is a perfect device for a teen as it’s geared toward those who are at the start of their fitness and health journey. 

Inspire versus Inspire 2

In terms of the differences to the first generation, it’s more evolution than a full remake. For example, it has an improved design and new features to encourage new-to-fitness users to make healthier choices. Unfortunately, there’s no GPS, which can be an additional useful feature for a parent with younger children. 


The Inspire 2 isn’t much different from the Inspire HR, and they both come with either a white, black or rose band. Compared to the predecessor, it’s slimmer, but not significantly. Also, Fitbit removed the physical button on the side of the reasonably small 0.7inch PMOLED touchscreen display.

Activity tracking

Firstly, Inspire 2 was the first in the range to offer Active Minute Zones, a new feature that follows health guidelines for exercise. Meaning, it’ll help you to reach goals each week, get a certain number of steps in or hit given heart rate zones. Although this might be a little too in-depth for your younger children, it might get your older kids interested in how their bodies work. But you do get a year of free Fitbit Premium which opens up a range of activities including instructor-guided ones, which may be useful. What’s more, there are meditation and breathing sessions to help them relax as well as hitting their active targets.

Sensors and features

Additionally, there’s sleep tracking which will give you a sleep score to indicate the quality. As a parent, it’s handy to know if your teens have been staying up until the early hours, which might explain why they’re so lethargic! 

Also, the Inspire 2 lacks a SpO2 sensor, so you can’t track blood oxygen levels. But, the lack of sensors and GPS mean you get a great battery life of up to 10 days, which is great for any Fitbit.

However, if the lack of GPS is a deal-breaker for you, don’t worry and keep reading.

However, if you want to actively encourage your teen to get up and move about then we recommend you opt for a Fitbit tracker that comes with a free one-year subscription to Fitbit Premium, where you can utilize all the features and guided workouts so your teen doesn’t have to go it alone or without any knowledge of where to start.

Perhaps GPS is an important feature, in which case, again, the Charge 4 is your best option.

Finally, if you’re after something that is a compromise between a fitness tracker and a smartphone because they struggle to put theirs down, we recommend the Lintelek or Letscom, which does a decent job of both functions at a minimal cost.
