Fitbit Inspire 3 vs 2 (2022): Is It Time To Upgrade?

If you’re not keen on a smartwatch because of its size, then slim, unobtrusive fitness trackers may be right up your alley. The Fitbit Inspire 2 is one of the most popular in this category, thanks to its size, style, and features. It’s also one of the best fitness trackers under $100. But with the release of the Fitbit Inspire 3, is the budget second-gen model still worth getting? On the Inspire 3, Fitbit introduces a much-awaited facelift to the Inspire lineup. Does this refresh make it a better option? Below, we lay out a quick Fitbit Inspire 3 review while pitting it against its predecessor.

Design and Hardware

The Fitbit Inspire 3 refines the design of the Inspire 3 and adds a color AMOLED display.

On the outside, the Fitbit Inspire 3 simply refines the design of its predecessor. You still get a narrow display but with rounded corners. Its case is also more proportional than the trapezoid-like form of the Fitbit Inspire 2. Plus, the Fitbit Inspire 3’s screen gets a slight bump in size to 1.5 inches from the Inspire 2’s 1.4 inches.

These are still small displays compared to what you get on an Apple Watch or Fitbit Sense. But two haptic buttons on either side of the case should make navigation less tedious. And since they’re haptic, they keep the trackers lightweight.

Power up the Inspire 3’s display, and you immediately see the big change. The third-gen Inspire now features a color AMOLED display similar to the Fitbit Charge 5. It boasts a 124 x 206p resolution and comes protected by Gorilla Glass. The bright color screen works well even under direct sunlight and is a major facelift over the greyscale OLED display on the Inspire 2.

Under the hood, the Fitbit Inspire 3 is equipped with a 3-axis accelerometer, an optical heart rate monitor, and a vibration motor. However, the Inspire 3 also adds an ambient light sensor and red and infrared sensors for blood oxygen monitoring.

Like most Fitbit wearables, the latest Inspire model comes with two bands out of the box — one small and one large. They’re still swappable with other straps, including the dressier stainless steel mesh and made-for-diving translucent bands. And speaking of water, both trackers are water resistant up to 50 meters.

Fitness and Tracking

Building on the features of the Fitbit Inspire 2, the Inspire 3 adds Sleep Profile and SpO2 monitoring.

Fitbit’s bread-and-butter is arguably fitness tracking. Both the Fitbit Inspire 3 and Inspire 2 offer staples, from counting your daily steps to measuring calories burned. The wearables also track real-time pace and distance, although you need to connect them to your phone’s GPS. But as basic fitness trackers go, the Inspire 3 and 2 have you covered.

In terms of workouts, you get over 20 on both models. Some exercises include running, walking, swimming, and yoga. AutoTrack, which automatically detects your activity, remains available on the Inspire 3. And to keep you motivated, Active Zone Minutes is supported by both wearables, advising you of the heart rate zone you enter while working out.

These days fitness trackers are more than just workout companions. Sleep tracking, for instance, is a key feature in many wearables. Fitbit has always excelled in this area, providing users insights like sleep stages and assigning sleep scores. While this is present in the Fitbit Inspire 2, the Inspire 3 adds Sleep Profile, a feature that looks into a month-long analysis of your sleep.

When it comes to other health features, the Fitbit Inspire 3 and 2 are quite similar. Both models track skin temperature variation, 24/7 heart rate, breathing rate, and stress. But for the Inspire 3, the biggest addition in this department is SpO2 monitoring. This brings the tracker up to par with Fitbit’s other models like the Luxe and Charge 5 without the extra cost.

Smart Features

Fitbit’s Inspire 3 and Inspire 2 fitness trackers have basic smart features.

Unlike smartwatches, the Fitbit Inspire 3 and Fitbit Inspire 2 have limited smart features. At best, call, text, and app notifications are supported. Since these are also basic fitness trackers with narrow displays, calling back or texting a reply is simply impractical. You can answer or reject a call but would still need your phone nearby.

The Fitbit Inspire 3 has also ditched the Inspire 2’s Tile app integration. In the latter’s case, this feature came in handy finding a missing tracker out of Bluetooth range. Instead, the Inspire 3 has a Find Phone functionality, arguably because it’s likelier to lose your phone than a tracker you’re wearing on your wrist.

Of course, what’s a Fitbit without customizable clock faces? If you’re one to personalize, the colored options for the Inspire 3 are better than on the Inspire 2. Plus, you get always-on mode on the latest iteration.

Subscription and Battery Life

Both the Fitbit Inspire 3 and 2’s key features are behind a paywall.

To access the Fitbit Inspire 3 and 2’s full features, you need to sign up for Fitbit Premium.

While the fitness and health insights you get from the Fitbit Inspire 3 are impressive, you have to remember this is Fitbit we’re talking about. As expected, the best features from the new iteration are behind the Fitbit Premium paywall. These include Sleep Profile, Wellness Reports, and expanded fitness and health content.

Fitbit Premium currently costs $9.99/month. If you buy the Inspire 3, it already comes with a six-month membership for free. However, that’s half the trial subscription you get from the Fitbit Inspire 2. But if you’re keen on joining Premium, you can get the Inspire 3 bundle with a one-year subscription and two-year protection plan to save money.

Meanwhile, battery life is the same for the two wearables. Like its predecessor, Fitbit advertises the Inspire 3 to deliver up to 10 days of battery. While it’s technically not an upgrade, you have to consider that a color display consumes more energy. So given the change in display tech for the Inspire 3, more than a week of battery life is above average.


For its color display alone, the Fitbit Inspire 3 is a worthy upgrade from the Fitbit Inspire 2.

In terms of features, the Fitbit Inspire 3 isn’t a massive upgrade from the Fitbit Inspire 2. If anything, the deeper Sleep Profile insights and the inclusion of a SpO2 sensor make it a more complete device. Moreover, the advanced functionalities are available only behind a Fitbit Premium subscription. And on the Inspire 3, the trial period is halved from the Inspire 2.

Instead, the Inspire 3 banks on its new color display. And as we’ve seen before, color does make a difference, allowing for more engagement from the user. Given this design update, it’s surprising but also welcome to find the Inspire 3 has the same battery life as its predecessor. Combined with Fitbit Inspire 3 specs, you’re looking at the strong contender for best fitness tracker of the year.
