Fitbit Charge 3

Unlike the Charge 2, this comes with a premium-feel aluminum body – the last version used stainless steel – which looks good on your wrist, doesn't feel uncomfortable on your skin and comes in the color choices of charcoal black or rose gold.

We'd expect Fitbit to launch some more colors in the future as this is quite a limited selection, but there’s no guarantee of that.

One thing to note is how there aren't any pressable buttons on the Charge 3. That's because this one has a full touchscreen rather than the tap-to-cycle screen we saw on the Charge 2.

You'll do most of your navigating around its features with your finger on the display, but there is also an inductive button on the left side of the tracker.

The tracker is fully waterproof up to 50 meters though, so you'll be able to comfortably take this swimming or in the shower without having to worry about whether it will survive.

Fitness features

All of the top-end fitness features on the Fitbit Charge 2 are back here for the Charge 3, so you’ll have the 24/7 heart rate tracking, workouts, guided breathing, and much more.

The biggest upgrade is the swim tracking you'll get on the device. It doesn't seem to be as robust as on some dedicated swim tracking watches, but it will tell you the duration of your dip in the pool when you look down at your wrist mid-way through your strokes.

Other stats, such as your length time and pace, can be found in the Fitbit app when you get out of the pool.

All workouts are now improved - there are now 15 different sports – as you can set your goal directly from your wrist.

Want to work out for 30 minutes exactly? You can set that as a target and get cycling. Want to burn 500 calories running today? You can set that up and get buzzed on your wrist when you're done.

Runners may be disappointed to learn there isn't any dedicated GPS on this tracker. It is a shame considering far cheaper products on the market are capable of tracking your location without your phone, but the Charge 3 does have Connected GPS, so you'll be able to keep an accurate eye on your distance if you're willing to carry your phone with you.

Female health tracking is now on the wrist too, so you'll be able to use the Fitbit Charge 3 to track your next period. Ovulation tracking is also set to come to the Fitbit app later in the year, but you won't be able to see this on the tracker.

Sleep tracking makes a return here too. It will be able to provide a picture of your night with details on REM, light and deep sleep.

Plus Fitbit is working on a new tool called Sleep Score that will be able to use the SpO2 sensor in this tracker to keep an eye on your breathing as well as using the heart-rate tracker to provide even more insight into your sleep.

Smart features

The Charge 3 is the closest Fitbit has come to merging its smartwatches with the more basic fitness devices it's best known for.

This device will be able to provide you with better smart notifications from all of the third-party apps on your phone than the Charge 2, which is only capable of alerting you to phone calls and a few other things.

You aren't able to download apps to this like you can with the Ionic or Versa, but there are a few features on board, including alarms, timers and weather. Later in the year you'll also be able to accept or reject calls from the device too, plus a calendar and the Fitbit Leaderboard are coming to the Charge 3 soon as well.

If you're using an Android phone, you’ll also soon be able to do quick replies to your messages. Essentially this allows you to reply to instant messages and the like with a number of basic responses, such as to say you're running late.

Fitbit estimates the battery life for the Charge 3 will mean it lasts for seven days rather than the quoted time of five on the Charge 2.
