Fitbit 4 Review

If you’re looking for a smartwatch that can track your workout, consider the Fitbit Charge 4. This device offers the SpO2 sensor, Swim tracking, and Fitbit Pay and is available for both men and women. With so many features and upgrades, it’s easy to see why the Charge 4 is so popular. In this Fitbit 4 Review, we’ll cover the pros and cons of both watches. Whether you need a heart rate sensor or swim tracking, we’ve reviewed the most important aspects of both devices.

Fitbit Charge 4

If you’re considering purchasing a new fitness watch, you might want to take a closer look at the Fitbit Charge 4. This sleek wristband tracks your heart rate and a wide range of activities, including walking, running, and swimming. Plus, the Charge 4 is water-resistant up to 50 meters. One of its nice features is the ability to program up to six shortcuts to your phone’s fitness app. This is useful for setting goals for runs, such as a specific distance. It can also help you keep track of your workout by allowing you to see how many calories you’ve burned and the amount of time you’ve been inactive.

Despite the Charge 4’s many advantages, the device is not completely accurate. Its data have margins of error, but it can help you set goals for yourself and become more conscious of your health. While the Fitbit Charge 4 doesn’t track heart rates in HD, it’s a great addition to any fitness or health-conscious person’s gear. However, to get the most out of the device, it’s important to learn how to care for it properly.

The Fitbit Charge 4’s proximity-based proximity detection is an excellent feature for active people. It can also be used to make payments without a credit card or wallet. The Charge 4 supports Fitbit Pay, which works like Apple Pay or Google Pay, but has a small number of participating banks. It also includes alarms, a stopwatch, and a timer. It even features a music player. In addition, it can play music from Spotify.

SpO2 sensor

A new feature on the Fitbit 4 lets you track your SpO2 levels throughout the night. The SpO2 scale measures your blood oxygen level on a 10 percent to 100 percent scale. The high 90s mean your levels are normal, while the low 90s are dangerous. The SpO2 sensor on Fitbit watches will activate by 2020. A doctor’s advice is always a good idea before using a fitness band.

The SpO2 sensor on the Fitbit Charge 4 is one of the few fitness trackers that track your blood oxygen levels. Unfortunately, this new feature isn’t available in the Fitbit 4’s pricey premium model, but you can still see your blood oxygen level on your wrist. To see your SpO2 level, swipe up on the home screen and tap on the Pulse Ox icon. Once you have completed this step, your Fitbit will display your blood oxygen level from the previous night.

The SpO2 sensor is available on the Fitbit Charge 4 in the Fitbit app or on the clock face of the device. You can enable or disable the feature depending on your needs. Enabling SpO2 tracking all day will cost you battery life, but you’ll be able to monitor your SpO2 levels at any time. To turn on the SpO2 feature, you’ll need the Fitbit Health Metrics app, which is available in select markets, such as the US.

Swim tracking

The Fitbit swim tracking feature tracks the number of laps you swim, how long you swim, and your pace. It also tracks major exercise activities such as running, cycling, and hiking. In addition to swimming, the swim tracking feature tracks your heart rate, total steps taken, and active minutes. The swim tracking feature works well with swimsuits as it keeps track of your swimming speed and duration. You can also set goals for your workouts and receive real-time reports.

Another great feature of swim tracking on the Fitbit Charge 4 is its water resistance of up to 50m. You can also integrate an exercise swimming app to use the swim tracking feature. The Fitbit Charge 4 also tracks your outdoor runs and bicycle rides. The device also allows you to track your heart rate, distance, and pace, as well as your outdoor runs. You can even listen to music on the go with the swim tracking feature.

If you prefer a sleeker design and more advanced features, the Fitbit Inspire HR is a great option. Its lightweight and seamless design won’t distract you from your workout. The battery life is reasonable, and the watch will stay on your wrist for up to two days on average. The Versa Lite is also cheaper than the Fitbit 4 and is ideal for a daily fitness tracker. While you’re deciding on a swim tracking feature, consider your budget.

Fitbit Pay

The Fitbit 4 review shows some differences compared to the first one. While other fitness trackers use heart-rate zones, the Fitbit uses active minutes, or the time spent in the different zones, to track a person’s progress. One credit is awarded per minute of moderate activity in the Fat Burn zone and two for vigorous activity in the Cardio or Peak zones. The app is easy to navigate and easy to understand. While the Fitbit watch isn’t perfect, it’s pretty darn close.

The first thing to note about the Fitbit Charge 4 is its thin design. The device is about half an inch thick at its thickest point. However, the display doesn’t look particularly great. The screen is also rather dull compared to that of other fitness trackers, and the design isn’t exactly eye-catching. The Fitbit 4 Review looks at the Charge 4’s design in more detail, including the band’s materials.

If you’re considering a fitness tracker, the Fitbit Charge 4 is a good choice. It has GPS capabilities and measures the percentage of time you spend in high heart rate zones. It’s also affordable. The Charge 4’s price tag is just $99, so it’s a good alternative to a smartwatch. In addition, you’ll be able to customize it to fit your wrist. The Fitbit Charge 4 looks great on a wrist and is easy to use. The Fitbit Charge 4 has some features, but it’s still not as advanced as the Fitbit Charge 4 or the Apple Watch.

Battery life

The battery life of Fitbit 4 depends on your usage. Some models can last seven or ten days without recharging, while others can only last five hours when GPS is turned on. In our tests, the Fitbit Charge 4 had an eighty-five percent battery after 24 hours. With GPS turned on, the battery life declined more quickly, though it still lasted a full day. So, it would help if you planned to charge your Fitbit regularly to avoid losing battery life too soon.

The Fitbit Charge 4 has a touchscreen for notifications and other features. It can also be used for Do Not Disturb mode and can last up to seven days on a single charge. In addition, this model supports smartphone notifications and can last up to five hours of continuous GPS usage. The battery life of Fitbit Charge 4 is similar to that of Charge 3, though it is shorter. Battery life is a major concern for many, so it’s best to keep track of your usage habits and set your expectations accordingly.

The Fitbit Charge 4 is also a great option for those who don’t necessarily need a GPS watch but still want a fitness tracker that can track your steps and distance. With the Charge 4’s improved sensors, you can easily track your distance in 50 meters. Its display is also twice as bright as the Charge 4’s. Both models have auto brightness settings and will work without a charger, which can reduce the battery life of both devices.


The Fitbit Charge 4 started at $149 and is currently available for just under $100. The Fitbit Charge 5 is the same device but with additional features. Its price has increased slightly, but the deal is still great. The Fitbit Charge 4 is currently available for under $100, and it regularly goes on sale. The Fitbit Charge 5 is still relatively new, so it hasn’t received many discounts yet. As a result, it’s hard to tell when it’ll hit the $179 mark.

The price of the Fitbit Charge 4 is currently around $150, but you can get it for as low as $130 today at Amazon. While it doesn’t have built-in GPS, it does have a wide range of swappable bands. It also tracks heart rate, sleep, and workouts. However, it’s not as stylish as the Charge 4 or Fitbit Luxe. If you’re looking for a more fashionable smartwatch, consider the Fitbit Luxe, which is currently listed for $130. Both devices can track heart rate, sleep, and workouts, but the Fitbit Luxe is less expensive than the Fitbit Charge 4 and the Charge 4.

Despite the Charge 4’s many improvements over its predecessor, it still falls short when it comes to features. Fitbit hasn’t changed its formula, so the Charge 4 isn’t exactly a breath of fresh air. However, compared to its rivals, it’s hard to find a fitness tracker for under $200. However, the Fitbit Charge 4 is priced similarly to the Apple Watch, so a price reduction is likely coming soon.
