As a fitness enthusiast and wearable technology expert, I was excited to get my hands on the Fitbit Charge 3.

Fitbit is a well-known brand in the fitness tracker industry, consistently delivering quality products that cater to various fitness needs.


In this comprehensive review, I will share my personal experience with the Fitbit Charge 3 and dive into its features, performance, and value for money. Let’s get started!

1. Design and Build Quality

a. Aesthetics and Comfort

The Fitbit Charge 3 boasts a sleek, modern design that’s both visually appealing and comfortable to wear.

With its slim profile and lightweight construction, it’s barely noticeable on my wrist during workouts or daily activities.

The device also features a larger display than its predecessor, the Charge 2, making it easier to read and navigate.

b. Durability and Water Resistance

Built to withstand everyday wear and tear, the Charge 3 is highly durable, featuring a sturdy aluminum case and damage-resistant Gorilla Glass 3 screen.

Additionally, the device is water-resistant up to 50 meters, making it suitable for swimming and showering without worry.

2. Display and Interface

a. Touchscreen and Greyscale OLED

The Charge 3’s greyscale OLED touchscreen is a significant improvement over the Charge 2’s monochrome display.

The touchscreen is highly responsive, and I found it easy to swipe through menus and access various features. The greyscale display allows for better contrast and readability, especially in bright sunlight.

b. Customizable Watch Faces

One feature I appreciate is the ability to customize the watch face. Fitbit offers several options, allowing users to choose a design that best fits their preferences and needs.

Some watch faces prioritize fitness stats, while others focus on time and date.

3. Activity Tracking Features

a. Step Counting and Distance Tracking

As expected, the Fitbit Charge 3 tracks steps and distances with impressive accuracy.

I compared the Charge 3’s step count with my smartphone’s pedometer and found a minimal discrepancy between the two.

The device also calculates calories burned based on the user’s activity levels, age, weight, and height.

b. Heart Rate Monitoring

The Charge 3 features continuous 24/7 heart rate monitoring using Fitbit’s proprietary PurePulse technology.

During my testing, the heart rate readings were consistent with those of a chest strap monitor.

The device also provides resting heart rate measurements, which is a helpful metric for assessing overall cardiovascular health.

c. Sleep Tracking and Analysis

One standout feature is the Charge 3’s sleep-tracking capabilities. The device automatically detects when you’re sleeping and monitors sleep stages (light, deep, and REM) as well as overall sleep quality.

I found the sleep insights provided by the Fitbit app to be informative and helpful in making adjustments to my sleep habits.

d. Automatic Exercise Recognition

The Charge 3 can automatically recognize and record certain exercises, such as running, biking, swimming, and more.

While I found this feature useful for tracking workouts without manual input, it’s worth noting that it may not be as accurate as manually starting a specific exercise mode.

4. Additional Health and Wellness Tools

a. Female Health Tracking

Fitbit’s female health tracking feature is a welcome addition to the Charge 3, allowing women to log their menstrual cycles and track symptoms. This feature helps users gain a better understanding of their cycles and overall reproductive health

b. Guided Breathing Sessions

Another wellness feature I found particularly useful was the guided breathing sessions. The Charge 3 offers 2- and 5-minute sessions designed to help users relax and manage stress. Based on your real-time heart rate, the device guides you through deep-breathing exercises, which I found to be a helpful tool for mindfulness and stress reduction.

c. Personalized Reminders

The Charge 3 allows users to set personalized reminders for various activities, such as hydration, exercise, and sleep. These gentle nudges helped me stay on track with my fitness goals and develop healthier habits.

5. Smart Notifications and Connectivity

a. Call, Text, and Calendar Alerts

The Charge 3 offers smart notifications for calls, texts, and calendar events, which I found convenient for staying connected without constantly checking my smartphone. The device displays notifications on its screen, allowing users to read messages and see caller ID information at a glance.

b. Third-Party App Integration

Fitbit Charge 3 integrates with numerous third-party apps, including MyFitnessPal, Strava, and more. This compatibility allows users to sync their fitness data across platforms, providing a more comprehensive view of their health and wellness journey.

c. Smartphone Compatibility

The Charge 3 is compatible with both iOS and Android smartphones. I had no issues syncing the device with my phone, and the Bluetooth connectivity was reliable throughout my testing.

6. Battery Life and Charging

a. Long-lasting Battery Performance

Fitbit claims that the Charge 3 can last up to 7 days on a single charge, and I found this to be accurate during my testing. The device’s battery life may vary depending on usage, but overall, I was impressed with its performance.

b. Proprietary Charging System

One minor drawback is the Charge 3’s proprietary charging system, which requires a specific charger. While it’s not a deal-breaker, it can be inconvenient if you lose or forget the charger.

7. Customization and Accessories

a. Interchangeable Bands

Fitbit offers a variety of interchangeable bands for the Charge 3, allowing users to personalize their device and match their style. Bands are available in various materials, such as silicone, leather, and metal.

b. Premium Edition Options

For users seeking a more luxurious look, Fitbit offers a Special Edition Charge 3, featuring a woven band and a rose gold or graphite aluminum case.

8. Fitbit App and Social Features

a. Comprehensive Data Analysis

The Fitbit app provides an in-depth analysis of your fitness data, offering insights into your workouts, sleep patterns, and overall health. I found the app to be user-friendly and engaging, making it easy to track my progress and set new goals.

b. Goal Setting and Achievement

The app allows users to set personalized fitness goals and offers achievement badges as milestones are reached. These gamification elements motivated me to push myself and stay committed to my fitness journey.

c. Community Engagement and Challenges

Fitbit’s social features encourage community engagement, allowing users to connect with friends, join groups, and participate in challenges. These aspects fostered a sense of camaraderie and friendly competition, making fitness more enjoyable and social.

9. Price and Value for Money

a. Fitbit Charge 3 Pricing

The Charge 3 is priced competitively, offering a range of features and performance that rivals more expensive fitness trackers.

b. Comparisons to Competing Fitness Trackers

When comparing the Fitbit Charge 3 to other fitness trackers in its price range, I found that it offers a well-rounded feature set and excellent performance. Its combination of reliable activity tracking, sleep monitoring, smart notifications, and wellness tools makes it a great value for money.


The Fitbit Charge 3 is an impressive fitness tracker that offers a wide range of features, excellent performance, and great value for money.

Its sleek design, accurate tracking capabilities, and robust app experience make it a solid choice for anyone looking to monitor their health and fitness journey.

While it does have some minor drawbacks, such as the proprietary charging system and the potential limitations of automatic exercise recognition, these issues are far outweighed by the device’s many advantages.

As a wearable technology expert and fitness enthusiast, I highly recommend the Fitbit Charge 3 to anyone seeking a reliable and feature-rich fitness tracker.
