1. Fitbit Charge 5: The Best Fitbit Overall

Fitbit Charge 5

  • Display:04-inch AMOLED
  • Water Resistance: Up to 50 Meters (5 ATM)
  • Heart Rate Monitoring: Yes
  • ECG Monitoring: Yes
  • Swim Tracking: Yes
  • Contactless Payments: Yes
  • Battery Life: Up to 7 Days

The Charge 5 is one of Fitbit’s newest trackers and, in our opinion, the best overall Fitbit model. It borrows an impressive array of sensors and features from its predecessors and Fitbit’s other smartwatches and wraps it in a slim and stylish stainless-steel casing.

Charge 5’s most noticeable improvement over Charge 4 is its AMOLED display, now 11% larger too. It’s easy to read under bright conditions, making it ideal to use outdoors. However, the lack of physical buttons takes some points off the usability score.

The Charge 5 features ECG and EDA stress sensors, the first time we’ve seen these on this particular wearable form factor. The latter can record irregularities in your skin’s electrodermal activity and estimate your stress levels to let you know when to relax.

It also has built-in GPS to track your running and biking routines, alongside the good-old suite of 24/8 HR tracking, Active Zone Minutes, and sleep and stress tracking. And based on heart rate variability, sleep time, and fatigue, the tracker provides a “Daily Readiness Score” to its wearers.

If you’re looking for a fitness tracker that does a phenomenal job tracking your fitness while also looking stylish on your wrist, the Fitbit Charge 5 is your best bet at the sub-$150 mark.

Pros Cons
Bright and vivid AMOLED display Navigation can get laggy sometimes
Impressive sensors array No physical navigation buttons
Loads of health/fitness tracking features Altimeter from Charge 4 is missing
Built-in GPS No onboard music

2. Fitbit Sense: Flagship Smartwatch With Premium Features

Fitbit Sense

  • Display:58-inch OLED
  • Water Resistance: Up to 50 Meters (5 ATM)
  • Heart Rate Monitoring: Yes
  • ECG Monitoring: Yes
  • Swim Tracking: Yes
  • Contactless Payments: Yes
  • Battery Life: Up to 6 Days

The Fitbit Sense is the brand’s premium smartwatch that somewhat shares the same design and feature set as the Versa lineup, but with more advanced wellbeing features. It’s also the costliest Fitbit model in the bunch but worth it if you’re looking for a bit more detail than just your daily step count.

The Fitbit Sense comes with an FDA-certified ECG sensor to check for irregularities in heart rhythms and supports blood oxygen reading. It also has an EDA sensor that can measure electrodermal activity and skin temperature for stress monitoring and indicate the onset of common illnesses.

Of course, the watch also has all-day heart rate monitoring and sleep tracking capabilities. In fact, it has all the fitness features from the other Fitbit and is the best Fitbit smartwatch for in-depth health insights.

Sense users will also find the Fitbit Premium subscription most useful. It unlocks access to detailed graphs of resting heart rate, respiratory rate, blood oxygen saturation, heart rate variability (HRV), skin temperature, and more, presented in the streamlined “Health Metrics” dashboard in the Fitbit app. Such readings can help users paint a picture of their overall health and wellness.

Additional features of the Fitbit Sense include apps support, notifications with quick replies, built-in GPS, Alexa, and Fitbit Pay. Fitbit claims six days of battery life with the Sense and less than 12 hours with GPS turned on. It does support fast charging.

Pros Cons
Comprehensive health and fitness features Pricey
On-wrist calls and notifications Average battery life
Big and bright OLED display Additional health data locked behind paywall
Amazon Alexa for hands-free voice prompts

3. Fitbit Luxe: The Most Fashionable Fitbit

Fitbit Luxe

  • Display:76-inch AMOLED
  • Water Resistance: Up to 50 Meters (5 ATM)
  • Heart Rate Monitoring: Yes
  • ECG Monitoring: No
  • Swim Tracking: Yes
  • Contactless Payments: No
  • Battery Life: Up to 5 Days

Functionality-wise, the Fitbit Luxe is quite similar to the Inspire 2, but what separates it from the latter are the aesthetics and slightly slimmer build. Inspired by jewelry and other fashion accessories, Luxe’s design is more about fashion statement compared to its more sporty alternatives.

However, at the same time, it’s very competent at fitness tracking. It has an optical heart rate monitor, red and infrared sensors for SpO2 monitoring, and other essential components for your typical daily step counts and exercise tracking. It doesn’t have GPS and relies on your phone’s tracker.

The Luxe also supports well-being features like sleep monitoring, stress management, guided breathing sessions, menstrual cycle tracking, and additional health metrics in the Fitbit app. However, one must pay for the Fitbit Premium subscription to access most of the following features.

The Fitbit Luxe’s design aims to appeal to female users with its stainless steel housing and jewelry-inspired accessories. A wide variety of accessory bands is available for the Luxe, including a soft-gold colored stainless-steel Parker Link bracelet from jewelry brand Gorjana and a Peony waterproof silicone band.

The Fitbit Luxe is an excellent pick if you’re a fashion-forward person looking to stay fit and healthy. Other than the Special Edition, it’s available in three distinct colors: Lunar White (Soft Gold Stainless Steel), Black (Graphite Stainless Steel), and Orchid (Platinum Stainless Steel).

Pros Cons
Slender and stylish design No Altimeter and GPS
Basic fitness tracking No Fitbit Pay
Color AMOLED touchscreen Somewhat limited health monitoring suite
20+ built-in exercise modes

4. Fitbit Versa 3: Fitness Smartwatch For The Masses

Fitbit Versa 3

  • Display: 58-inch AMOLED
  • Water Resistance: Up to 50 Meters
  • Heart Rate Monitoring: Yes
  • ECG Monitoring: No
  • Swim Tracking: Yes
  • Contactless Payments: Yes
  • Battery Life: Up to 6 Days

The Fitbit Versa 3 is the company’s mid-range wearable that builds upon its predecessors, covering nearly every critical aspect of a fitness tracker and adding them in a typical smartwatch form factor. Its larger, curvier screen and onboard GPS are two of the most significant upgrades over the previous Versa 2.

The Versa 3, like the Fitbit Sense, runs Fitbit OS, enabling handy features such as on-wrist notifications, music controls, apps marketplace, smart home controls, Alexa and Google Assistant voice assistant integration, etc.

Users can also connect Bluetooth headphones directly to the watch and listen to their Spotify, Pandora, and Deezer playlists. And thanks to its built-in speaker and microphone, users can answer and respond to phone calls. The big and bright screen also allows monitoring goal progress without the phone.

Unlike Sense, Versa 3 doesn’t have the EDA and ECG sensors for stress monitoring, skin temperature measurements, and detecting irregular heart rhythms.

Thankfully, it can still measure the rest of the vital metrics like steps, heart rate, calorie burns, active zone minutes, SpO2, cardio zones, and sleep. It also has 20+ built-in exercise and workout modes. Heart Rate Notifications, previously a Sense-exclusive feature, is now available on Versa 3.

If the Fitbit Sense is out of your budget range and you’re willing to miss out on stress management and ECG readings, go for the Versa 3. It’s significantly cheaper and delivers nearly all the fitness features as the top-end Fitbit model.

Pros Cons
Extensive fitness tracking capabilities HR measurements can be imprecise sometimes
On-wrist calls and notifications with replies Iffy navigation
Onboard storage for music Average battery performance
Built-in GPS

5. Fitbit Inspire 2: Covers All The Basics

Fitbit Inspire 2

  • Display: 7-inch Grayscale OLED
  • Water Resistance: Up to 50 Meters
  • Heart Rate Monitoring: Yes
  • ECG Monitoring: No
  • Swim Tracking: Yes
  • Contactless Payments: No
  • Battery Life: Up to 10 Days

Fitbit’s entry-level model, Inspire 2, is ideal for those trying to get into the Fitbit ecosystem without completely emptying their wallets. It’s a slight upgrade to the Inspire HR with its marginally better screen and support for Fitbit’s Active Zone Minutes feature.

Tracking-wise, the Inspire 2 covers pretty much all the essentials: steps, heart rate, sleep stage measurements, covered distance, swim tracking, auto workout detection, on-wrist notifications, and more. It’s as capable as its more expensive Charge counterparts except for the Altimeter and GPS capabilities. There’s no app support either, and it also lacks support for contactless payments.

After all, the Inspire 2 is one of Fitbit’s cheapest fitness trackers. It makes for the following omissions by providing access to detailed health and fitness data through the Fitbit mobile app. Having less hardware also contributes to the tracker’s 10-day battery life, making it the longest-lasting Fitbit in the bunch.

Pros Cons
Reasonable price Somewhat generic design
Slender and lightweight Lackluster screen
Ideal fitness tracker for novices No GPS built-in
Fitbit Pay is missing

6. Fitbit Versa 2: Old, But No Slouch Either

Fitbit Versa 2

  • Display: 34-inch AMOLED
  • Water Resistance: Up to 50 Meters
  • Heart Rate Monitoring: Yes
  • ECG Monitoring: No
  • Swim Tracking: Yes
  • Contactless Payments: Yes
  • Battery Life: Up to 4 Days

If you’re budget-constrained but still want a Fitbit smartwatch, the Versa 2 is a godsend. Since the debut of its successor, Fitbit has permanently slashed the price of this model.

Sure, it has a slightly smaller screen, a less accurate HR sensor, lacks built-in GPS, and doesn’t support on-wrist calls, but other than that, it can do almost everything that the Versa 3 can. Apart from the typical heart rate and sleep tracking features, the Versa 2 can also monitor blood oxygen saturation levels and alert users about certain sleeping disorders.

Not to mention, the Versa 2 runs Fitbit OS and has onboard storage for up to 300 songs, meaning you can leave your phone at home and listen to your beats on the go. It also has third-party app support and Fitbit Pay.

As long as you can find a Versa 2 at its discounted price (Fitbit still sells it on their official store at the time of writing), it remains an excellent choice for a fitness smartwatch.

Pros Cons
Large and vivid display Mediocre battery life
Runs Fitbit OS No integrated GPS
Rich fitness and sleep tracking features Clumsy Alexa integration
Available at discounted prices

7. Fitbit Ace 3: Best Fitbit For Kids

Fitbit Ace 3

  • Display: 7-inch OLED
  • Water Resistance: Up to 50 Meters
  • Heart Rate Monitoring: Sensor present but disabled
  • ECG Monitoring: No
  • Swim Tracking: No
  • Contactless Payments: No
  • Battery Life: Up to 8 Days

The Fitbit Ace 3 is a rudimentary fitness tracker for children of age between 6 and 13. Designed to encourage kids to exercise, Ace 3 allows parents to set health goals for their children in a fun and engaging way. Instead of just showing boring metrics, the Ace 3 also offers achievements that kids can unlock by completing various activities.

The Ace 3 features a rugged outer shell and a flexible silicone wrist band. It’s lightweight, comfortable, and safe to wear for prolonged periods. It’s also water-resistant to 50 meters, meaning kids can wear it in the pool without damaging the tracker.

The tracker displays key activity stats like steps and active minutes on the screen and has 8-day battery life. Furthermore, kids can pick from dozens of animated clock faces through the Fitbit app when set to Kid View. Parents can set bedtime reminders and sleep schedules from the Fitbit app’s Parent View, as well as use the timer and stopwatch features to guide homework time.

Getting a Fitbit Ace 3 for your kids is a fun way to grab their attention and encourage them to go play outside. It’s also fairly affordable for a basic fitness tracker.

Pros Cons
Kid-friendly fitness tracking Monochrome screen
Rugged and lightweight Heart rate sensor is present, but disabled
Excellent parental controls
Long-lasting battery

FAQ: Which Fitbit Offers The Best Battery Life?

All Fitbit models come with non-removable rechargeable batteries. If you’re looking for the best battery life from a Fitbit, the Inspire 2 with its staggering 10-day runtime is your best option. Of course, you can get similar battery performance from a Charge, Versa, or Sense model too by disabling resource-intensive features like Always-on-Display and GPS. Here’s how long each Fitbit model can last on a single charge:

  • Charge 5: Up to 7 Days
  • Sense: Up to 6 Days
  • Luxe: Up to 5 Days
  • Versa 3: Up to 6 Days
  • Inspire 2: Up to 10 Days
  • Versa 2: Up to 4 Days
  • Ace 3: Up to 8 Days

Once again, it’s worth noting that AOD and GPS on supported Fitbits will significantly reduce the battery life when turned on.

FAQ: Does The Fitbit App Work With All Models?

Yes, the Fitbit app works with all Fitbit models and is compatible with Android, iPhones, iPads, and Windows. Regarded as one of the best and most mature health apps in the industry, the official Fitbit app arranges all your daily stats and data collected in the past in beautiful, streamlined graphs.

Additionally, users can sign up for the Fitbit Premium subscription to unlock personalized health and fitness programs, video workout guides, etc. It also gives access to more in-depth data analysis, providing users with daily wellness reports and more.

Finally, you can set daily, weekly, and monthly fitness goals from the Fitbit app. And if you happen to have friends and families using Fitbit, you can connect to compete against them on the leaderboard and participate in various fitness challenges.
