Fitbit Ionic review

Fitbit has become synonymous with fitness trackers, but now, with the company in its tenth year, it’s decided to expand into a whole new market. Long rumored, we finally have the first Fitbit smartwatch, and it’s called the Ionic.

The company has combined its fitness know-how with the smarts of a variety of companies it’s bought – such as Pebble, which Fitbit acquired in 2016 – and brought it all together to add an impressive new wearable to its range.

Offering similar features to expensive alternatives such as the Apple Watch 2 and Android Wear, the Fitbit Ionic is a serious contender to be the smartwatch you choose to wear when you’re out running or hitting the gym.

However, there's now the additional competition of the new Apple Watch 3, which includes the same LTE connectivity feature as the Fitbit Ionic.

Fitbit Ionic price and release date

• The Fitbit Ionic costs £299.95 / $299.95 / AU$449.95 
• It's an expensive option for a fitness watch
• Out now around the world

The Fitbit Ionic is the most expensive wearable yet from Fitbit. At £299.95 / $299.95 / AU$449.95 it costs more than the Fitbit Surge running watch, but a bit less than the Apple Watch 2 or LG Watch Sport.

You can now buy the Fitbit Ionic now around the world from a variety of different retailers including from the official Fitbit website.

Design and display

• Aluminium build and lighter than most smartwatches
• Either plastic or leather bands that are easy to swap out

The Fitbit Ionic is a comfortable fit on your wrist, and compared to a lot of modern smartwatches is particularly light – so much so that you'll instantly notice how lightweight this feels on your wrist, which makes it a more pleasant to wear while working out than, say, the LG Watch Sport.

It’s a comfortable fit for everyday use too, being comfortable to wear at a keyboard, which should encourage you to wear it all day to ensure the most accurate readings possible.

It’s waterproof, so you can take this in the shower or even go swimming with it – more on that in the fitness section.

The body of the watch is made of aluminum and features very small antenna bands on the sides, but it’s attractive and is easily the best-looking Fitbit product so far. That said, we found the design to be rather divisive, with friends and family either loving the look or hating it.

You may well love the look of the Fitbit Ionic, but if you’re bothered about what others think just bear in mind that it’s not likely to have the universal appeal of, say, the Apple Watch. 

There’s one hardware button on the left-hand side with another two on the right that sit in similar positions to those on the Fitbit Blaze and enable you to move around the watch’s UI.

Each is slightly raised too – Fitbit presumably thinks this will help you find them more easily when you’re fumbling around for the buttons while sweating and gasping for breath when pushing yourself.

We found the buttons worked for making the UI simple, plus it’s a touchscreen, so you can cycle through the apps by swiping.

There are leather and plastic strap options available with secure fasteners on each so the Ionic won't fall off when you're out for a jog.

We used both, and the plastic option is comfortable for when you’re sweating in the gym, while the leather strap is a much more attractive look – so you might want to get both if you want to wear this watch both for working out and dining out.

The display on the Ionic is a full-color screen that’s rectangular, unlike the more square Apple Watch or most Android Wear watches, but it is reminiscent of the Blaze’s screen. This one is quite a bit bigger though, and that’s down to the bezels being thinner.

That said, the bezels are relatively thick on the Fitbit Ionic. It’s one of our major criticisms of the design, and we think there’s a lot of wasted space below and above the screen. Fitbit could have included a much larger and more useful display instead.

Also, the Fitbit logo is annoyingly placed just below the screen, taking up quite a bit of room on the wearable. 

The resolution of the LCD screen is 384 x 250, and we particularly like how bright it is – it reaches 1000 nits, which is the same as the Apple Watch 2 and means you can view it even in bright sunlight when out on a run.

We found the touchscreen to be a little slow to respond sometimes, and we often had to move our wrist fairly violently for the raise-to-wake feature to work. That’s particularly annoying when you’re working out and you need a clear look at your stats fast.

Fitness features

• Suitable for running, cycling, swimming, weights and much more
• Comes with in-built workouts that you can follow on the watch
• We love the built-in GPS and heart rate monitor

All of the fitness features we’ve come to know and love on other Fitbit products are here, and there are a few upgraded elements too.

The Ionic features a heart rate tracker, which according to the company is even more accurate than on other Fitbits thanks to shiny new algorithms behind the scenes and a design that means it sits much closer to the skin.

We found it worked much quicker than on previous Fitbit products, and in our testing we found it to be as accurate as other trackers and watches on the market. This is particularly useful for exercising, and Fitbit will use your heart rate for a lot of the information that’s displayed in its workouts app.

There’s built-in GPS here too, and Fitbit reckons your connection should be better than on the Fitbit Surge as the antenna bands are placed in optimal positions to ensure a better tracking connection.

Connecting to GPS sometimes took a little longer than we’d have liked, but we never lost connection while running or walking. Being able to look through your data after you’ve been on a long run or ride is a big feature too.

New features for running include an automatic pause option, which will notice when, for example, you’ve stopped to cross at some traffic lights and pause your workout, then restart when you begin exercising again.

Fitbit has also included workouts in its new Fitbit Coach feature that is accessible from the watch and will offer a similar service to the Fitstar app you can download on your phone.

These are tailored workouts that will show you exactly what to do, and every time you complete one you can supply feedback so Fitbit Coach can work out whether you need something easier or harder next time.

The aim here is to help you improve, and while it seems like quite a basic system it should encourage you to try different types of exercise. 

Fitbit plans to also bring audio workouts to the Ionic – and they can’t come soon enough, because it’s a big missing feature here. When trying out workouts within the Coach feature, we found ourselves rushed to get onto the next part.

For example, it’ll start you off with 12 push-ups and give you a buzz on your wrist when you’re done, then tell you your next workout position and give you nine seconds to get ready.

Without an audio cue, you have to look at your wrist, study the form of the workout and then be ready to start, all within nine seconds. When you’re sweating and gasping for breath, we often found this was nigh on impossible.

Fitbit has also included an SpO2 sensor here to monitor blood oxygen levels – in a similar way to the Samsung Galaxy S8 – but the feature isn't enabled at launch, and is included as something Fitbit will hopefully push out at a later date.

We also now know the Fitbit Ionic is set to be a useful device for those with diabetes. If you pair the watch with a Dexcom G5 Mobile sensor (a specialist device that costs $900 (about £690, AU$1,120) it'll be able to display your glucose levels so you can monitor them.

It's an interesting concept, and it could make the Fitbit Ionic a must-have device for those with diabetes.

Performance and battery life

• Battery life lasts for four to five days from a single charge
• Some menus take a long time to load and can be frustrating when exercising

The exact internals of the Fitbit Ionic are a little unclear, and we don’t expect to know much about what’s running under the hood. In our testing, however, we found that the Fitbit Ionic user interface can be a little slow at loading.

For example, setting up a workout can take quite a long time compared to other competing devices, and it can also be frustrating when you want to get accurate fitness readings. We haven’t found that apps crash while using it though.

We found that the Fitbit Ionic’s battery lasted between four and five days with limited usage. If you’re going to be working out a lot with the watch it’ll be a lot less, and the battery gets hit especially hard when using GPS.

Fitbit estimates it lasts for 10 hours of constant GPS tracking, and we think that’s about right  – and it’s still around the same amount of time as your average running watch is able to last for.

You can also upload music to the Fitbit Ionic, with 2.5GB of free space at your disposal. That’s not much, and will only allow for around 300 songs, but if you have particular audiobooks, podcasts or albums you're always going back to there should be space for some of them here.

You can then connect Bluetooth headphones and listen to music on the go without having to take your phone on your run. 

We found the Bluetooth connection remained stable, but it’s irritating that you can’t integrate some of the most popular streaming services, such as Spotify or Apple Music, to download any music you want easily.

Instead you have to own the files and upload them manually using a computer, which all feels a touch too complicated, and encouraged us to just take our phone out on the run instead.

Those in the US will be able to link the Ionic up with Pandora, but we’ve yet to test that service and can’t confirm if it works well or not.

Apps and compatibility

• Works on iOS, Android and Windows Phone devices, 
• You'll need to be able to download the Fitbit app from your phone's app store
• Fitbit's App Gallery is currently limited, hopefully will improve soon

The Fitbit Ionic will work alongside the Fitbit app on your phone, which is compatible with most modern iOS, Android and Windows Phone devices.

The Ionic comes with its own App Gallery – Fitbit is insistent this isn’t an app store – that includes Fitbit’s own services as well as third-party apps. Right now it’s unclear what third-party options will be included in the future – it’s only Fitbit services and the Strava app for now.

And Fitbit is opening up the software building tools for third-party developers, so hopefully we’ll see other services such as Spotify get involved in the Fitbit space too, but it’s not yet possible to know how thorough support will be.

At launch, everything on the Ionic App Gallery is set to be free, but there may be paid-for alternative apps at some stage in the future. 

You can also choose a variety of watch faces within the Fitbit app, and there are currently lots of good choices. We hope the selection will be expanded in the future though, as there still aren’t as many options as you can get on alternative wearables.

Personalization isn’t possible here either – it would be nice to have the option to add different widgets to your prefered style of watch face. We have high hopes this will happen eventually, especially as it was a big focus for Pebble wearables in the past.

Fitbit has included mobile payments on the Ionic through its own service called – you guessed it - Fitbit Pay. This is based on tech from a company called Coin, which Fitbit bought a few years back, and will allow you to use NFC to pay on contactless terminals with your wrist.

Fitbit is partnering with Visa, American Express and Mastercard for this, but you’ll need to make sure your bank is offering the service, and we’re yet to hear which banks will be.

The feature has yet to launch officially and will come with a software update soon, but we’ve had time to play around with a beta version of the feature and it works well.

You hold down the button on the right-hand side of the Ionic for a few seconds to make a payment, and you’ll then need to enter a PIN number that you’ve previously set up and place your Ionic near to the reader.

It’s a very similar experience to either Apple Pay on the Apple Watch or Android Pay on Android Wear devices, and it’s especially useful if you need to grab a bottle of water when you’ve gone running without your wallet or phone.

It likely isn’t going to replace your wallet, but it’s a useful extra way of being able to make payments when you’re out exercising.

 Verdict

The Fitbit Ionic is a good wearable, but it’s not the great smartwatch some had expected it to be.

There are lots of positives, including strong battery life, Fitbit Pay and built-in GPS, but there’s also a lot missing, and that leaves this device feeling more like a fitness tracker, rather than a smartwatch in terms of features.

Controversial design is something Fitbit loves as well (remember the Fitbit Blaze?) and this isn’t going to be the most attractive device for everyone.

Who’s it for?

Fitbit has decided to bring a few smaller smartwatch features to a fitness tracker, so you’ve got the added benefits of things like Fitbit Pay, but they’re mostly useful in an exercise capacity – so if you’re looking for a fitness watch that goes the extra mile in terms of features, the Ionic could be for you.

It’s also for you if you like the Fitbit brand and have previously used the app. If you’re looking for something a little more substantial than a Fitbit tracker on your wrist but you don’t want to switch to another platform, this will suit you well.

Should you buy it?

Even if you fall into one of the categories above, however, it’s hard to recommend the Fitbit Ionic when there are so many great options out there for smart wristwear that offer better value.

Fitbit has priced the Ionic at around the same level as the most premium Android Wear and Tizen choices, as well as just below the Apple Watch 3, all of which offer a nicer design and better features.

If you really like the design of the Ionic, and think the fitness features on offer are worth the money, then this will be a good purchase for you, but there are lots of other smartwatches that we prefer.

The competition

Here we're going to run you through some of the alternative watches you may want to buy instead of the Fitbit Ionic.

Apple Watch 3

The latest wearable from Apple, the Watch 3 is its most accomplished smartwatch yet with LTE connectivity to allow you to use it truly without your phone. 

That's something the Fitbit Ionic can't offer either, so if you want to be able to go running without your phone and still receive phone calls you may want to opt for Apple's watch instead.

Fitbit Blaze

The Fitbit Blaze is much cheaper than the Ionic, but is a little more limited and isn't technically a smartwatch. 

It's closer to a fitness tracker, but with a much lower price and a focus on fitness features it may be a good alternative to the Ionic for you.

Samsung Gear S3

Samsung has a lot of experience making smartwatches now and the Gear S3 is arguably its best device yet. We gave it four stars when we first reviewed it citing an intuitive interface and great activity tracking features as the key highlights.

There are some issues such as a lack of apps - something the Ionic suffers from too - but that's something that's improving all of the time.
