Fitbit is one of the most well-known names in the fitness-tracking business, and for good reason: It combines a brilliant UI and attractive design to appeal to a wide range of people. The Fitbit Sense is no exception. It’s range of features and top-notch sleep tracking make it an easy choice for someone looking for a smart fitness watch at a lower price point than something like a Garmin.

The first thing that jumps out about the Fitbit Sense is its design. It has a clean, streamlined build that’s square with rounded edges. It’s not as bulky or gear-like in shape as something like the Garmin Epix, which makes it much more suitable for day-to-day wear, even in more formal environments. Swapping the bands is simple, too.

The back of the Sense is made of metal, which might cause a few problems if you’re allergic. I couldn’t get an answer as to the type of metal, but I did notice a bit of skin irritation after prolonged wear.

One thing to note is that the default band is on the smaller side. If you have larger wrists, you’ll need to trade out the bands for the longer option or it will be too tight (which aside from being uncomfortable can throw off sensor readings.) The latch also annoyed me; it slips through one loop and hooks into a hole on the band, while the excess length slides through a second loop. It wasn’t the easiest to put on or off.

If you have larger wrists, you’ll need to trade out the bands for the longer option or it will be too tight.

While navigating the Fitbit from the watch face is easy, I sometimes found the activation button to be slightly unresponsive, especially when I was sweaty. It also activated by accident on several occasions.

Sleep and health tracking

The Fitbit Sense excels at tracking vital information. There are four main areas it focuses on: Minutes in the “zone,” number of steps and floors, miles traveled, and calories burned. It also tracks the amount of time you spend asleep, as well as how much time you spend in each stage of sleep.

The standard watch face shows you the date, time, number of steps, your sleep score, and your current heart rate. There are multiple faces to choose from, and Fitbit can sync up with your phone to display your calendar, incoming texts and calls, and more.

The Fitbit Sense excels at tracking vital information.

Within the Fitbit app, you can log fluid and calorie intake, set a goal weight, and more. Fitbit reminds you to get up and move, and tries to get you take at least 250 steps each hour.

The Fitbit Sense also has stress management features. It allows you to log how you’re feeling at a given moment to to track your stress throughout the day. If you subscribe to Fitbit Premium, you will have access to even more features that break down your stress management response.

Fitbit Premium is $10 per month or $80 per year. When you purchase a new device, it comes with a six-month free trial to test it out. The subscription includes content from numerous Fitbit partners, including Popsugar, Aura, and more.

It also provides users with more detailed sleep tools, advanced insights into your health, better stress and mindfulness tools, and additional games and challenges to keep you motivated. Premium subscribers get access to information like their breathing rate, heart rate variability, skin temperature, oxygen saturation, and more.

Day-to-day performance

One area where the Fitbit Sense stands out from equivalent Garmin products is in its sleep tracking. While the Garmin struggled to keep up with irregular sleep patterns (especially if I woke up in the middle of the night and go back to sleep), the Fitbit Sense’s automatic detection was much more accurate. It calculates an overall sleep score based on how much I sleep throughout the day. If I only get six hours at night, but take an hour long nap later in the day, it updates the score to reflect that.

With a six-day battery life, I never worried about it running out of charge throughout the day. It only takes a short time to fully charge the Fitbit once it dies.

One of the most useful features is the ability to tap any health metric and get more information on what it means. So many fitness wearables have their own names for each section that it can be hard to keep track, but Fitbit makes it easy to know what you’re looking at.

One of the most useful features is the ability to tap any health metric and get more information on what it means.

For example, “Zone Minutes” is the number of minutes you spent in the Active Zone, or the heart rate range that counts toward exercise. The American Heart Association recommends at least 150 minutes of moderate exercise each week, and the Sense helps you track your progress toward that goal.

If you previously owned a Fitbit, your information is still available. When I activated the Sense and started tracking data, I found information from 2015 and earlier — the last time I wore a Fitbit. Of course, some of the information was lacking (the earlier models didn’t have the same trackers as the ones I wear now).

One final feature to note is that the Fitbit Sense integrates with Alexa and Google Assistant. With a tap of a button, I can give voice commands to my smart assistants from my wrist — a far easier alternative than pulling up the respective apps while on the go.

Social aspects

The Fitbit app includes a Community tab that lets you find a sort of social network for nearly any type of fitness you can think of. It suggests groups based on your activity within the app; for example, it recommended the Sleep Well and Vegetarian groups for me. The Sleep Well group is full of people posting their previous nights’ sleep scores and comparing progress in achieving a good night’s rest, while the Vegetarian group includes pictures of meals and recipe ideas.

You can link your phone’s Contacts with Fitbit to search for any friends who are on the app. You can also individually add people through email or by their username. Keeping in touch with your friends on the app can help keep you motivated.

Other great motivational and social aspects are the Badges and Trophies. These are awards you get for meeting specific fitness goals. For example, the Sneakers Badge is awarded if you walk 10,000 steps in a day. The Penguin March Badge is earned if you walk 70 miles in a lifetime, and the Lighthouse Badge is earned if you walk up more than 50 flights of stairs in one day.

These can be earned more than once and put on display on your profile.

Trophies are earned by completing challenges against other people. You don’t have to be connected with others to participate; instead, the app compares your progress to everyone else in the challenge. The Daily Showdown Challenge, for example, awards the trophy to whoever walks the most steps in one day in a given time zone.

Our take

The Fitbit Sense streamlines vital health tracking into an approachable platform, and its automatic detection makes it perfect for anyone trying to improve their sleep habits. While the interface can seem a little confusing at first, it’s actually easier to navigate that some of the comparable platforms on the market (like Garmin and its two separate apps).

Is there a better alternative?

The Fitbit Sense is an appealing choice because it’s so affordable. At just $300, there aren’t a lot of options with the same level of performance. If you want a smartwatch, the Apple Watch Series 7 is $350. The Garmin Lily has a more attractive design that looks the most like an actual watch of any fitness wearable I’ve ever seen, and it’s just $200.

How long will it last?

The Fitbit Sense is durable, and the screen hasn’t gotten scratched in the time I’ve used it. I suspect it will last for several years at least of day-to-day use. Fitbit offers a 45-day money-back guarantee for all purchases from its website, and the Sense comes with a one-year limited warranty in case something does happen.

Should you buy it?

Yes. At $300, the detailed health and sleep tracking can’t be beat. It’s a far more affordable option than many fitness trackers on the market, and the social community aspect means you’ll have workout partners from around the globe — as well as an attractive watch for daily wear.

Best Prime Day Fitbit Deals for October 2022
Prime Day 2022 fitbit deals graphic.

Are you looking for hot Fitbit deals for yourself or maybe as gifts for others? Well, pay attention because Amazon's two-day Prime Early Access Sale is almost over, it's the last day, which means all those amazing Prime Day Fitbit deals will be gone soon. Amazon calls it an "early access" sale because it gives you an extra-early start at shopping for the holidays well before the annual Black Friday extravaganza. Similar to Prime Day deals, we've seen tons of deep discounts on Amazon-owned brand products such as Echo, Ring, and Blink smart home devices, Kindles, Fire TVs, and Eero mesh Wi-Fi devices. Smartwatches and activity trackers are popular holiday gifts, and Amazon is offering some of the best prices of the year on new Fitbits as well as previous models of the popular wrist wearables.

Amazon isn't the only one having all of the fun though. Other retailers have joined in, as is to be expected, like Walmart's October Rollbacks event, which is basically just a Walmart Prime Day sale in disguise. Nevertheless, Amazon has some of the best offers! We've gathered up the best Prime Day Fitbit deals for you below!

Fitbit Versa 4 vs. Fitbit Sense 2: Which new Fitbit wins?
Lifestyle photo of the Fitbit Versa 4 and Fitbit Sense 2.

Fitbit is back with two new health-focused smartwatches, the Fitbit Versa 4 and the Fitbit Sense 2. Both watches are well-designed tools with health-tracking features, superseding the Fitbit Versa 3 and the original Sense.

While Google purchased Fitbit in the interim between both releases, these still use the company's proprietary Fitbit OS in lieu of Wear OS 3. For that, you'll need to get the Pixel Watch, the Samsung Galaxy Watch 5, or the Montblanc Summit 3. Instead, these releases from Fitbit iterate and refine what made their previous models so good. The good batteries and handsome designs remain, accompanied by changes to heft and feel and minor software tweaks here and there. With so much overlap, there's a question to be raised about which of the two is the better fit for your wrist and wallet, so which is better for you? We found out.

The Fitbit Versa 4 and Sense 2 are coming soon, and without Wear OS
Lifestyle photo of the Fitbit Versa 4 and Fitbit Sense 2.

Fitbit's lineup of smartwatches and fitness trackers is getting larger just in time for the holiday season, with the company announcing the Fitbit Versa 4, Fitbit Sense 2, and Fitbit Inspire 3. The Versa and Sense continue Fitbit's smartwatch focus, while the Inspire remains one of the go-to choices for anyone who wants to eschew too many smart features for a sleeker design and smaller price. And they're likely to be among the best Fitbit wearables you can buy this year.

Right off the bat, none of these wearables are significant new additions to Fitbit's portfolio. They're all very similar to their predecessors, but with a few minor tweaks here and there to make them better than before. And, no, none of the new smartwatches are running Wear OS. Fitbit has made some intriguing hardware and software upgrades across the board, but this latest launch is clearly focused on evolution rather than revolution.
