Now, however, the watch has dropped to only £235, making it an altogether much more tempting proposition.
The newer Fitbit Versa is £40 cheaper still at only £199, but if you want to track your runs or bike rides without taking your phone with you, the Ionic's buit-in GPS makes it the only sensible choice. Otherwise, the two wearables are almost identical in terms of features, so if you're not fussed about GPS, then the decision should come down which model's design you prefer.
Original review continues below:
Fitbit has led the way in the fitness band market for some time now, but in the smartwatch arena, it has struggled. Its first watch was the Surge, which worked well for fitness duties but struggled to compete with smartwatches for style or smart features. Its next effort, the Fitbit Blaze, wasn’t that much better, upping the ante on the style front, but omitting key features such as waterproofing and GPS. Finally, though, it seems as if there's a Fitbit watch that fixes these problems: the Fitbit Ionic. It looks great, has GPS and waterproofing and combines that all with smartwatch-style features.
The Ionic is the smartwatch Fitbit always wanted to make and, given its recent acquisitions of watchmakers Pebble and Vector, one it has also spent big to get right. In many ways, it has achieved this feat with the Ionic, but it's still far from perfect.
So, what are its key features? Well, this is essentially a combination of the Surge and the Blaze all in one sleek package. It looks wonderful – much nicer in the metal than in most of the photographs I’ve seen – and it’s packed with all the features you need in a top-end fitness-cum-smartwatch. There’s a heart-rate monitor, GPS, proper water-proofing to 50m, music playback support, it has a bright, colourful OLED display and even built-in NFC for making contactless payments.
Design, display and battery life
Of all its close competitors, though, it’s the Ionic that stands out for me, both in terms of the way it looks and its comfort on the wrist.
Some might not like its square-edged profile, preferring the softer edges of the Apple Watch or the more traditionalist round faces of the Samsung Gear S3 and Huawei Watch 2. I was of the same opinion – until I pried the Ionic from its box.
It’s available in three different colours – silver, burnt orange and dark metallic grey – it’s topped with a slightly convex Gorilla Glass 3 touchscreen and it looks gorgeous whichever one you go for. By default, the watch is supplied with a textured rubber wristband (both small and large are included in the box), but you can swap this out for the optional, £50 leather wristband or the two-tone £25 rubber sport band if you want a different look.
Alas, although the straps clip in and out neatly and easily, it isn't a standard fitting, so until Fitbit decide to release more strap options, that's all the choice you have.
Many of the Ionic's features are accessed via the touchscreen, but there are also three textured buttons on the sides of the watch: one on the left that activates and deactivates the screen and serves as a back button; and two context-sensitive function buttons on the right edge.
The design is subtly stylish and understated, but the OLED display is the star here. It's amazingly bright, reaching a peak of 1,000nit according to Fitbit and it's super crisp. For me, it's the best display I’ve seen on any smartwatch or fitness wearable. Most importantly it's incredibly readable, whether you’re pounding the pavement on your evening jog or cramming in the lengths at the local pool. Some might take issue with the black border surrounding it, but this does mean there’s room for a light sensor, which adjusts the brightness of the display automatically, depending on the ambient conditions.

On the rear is the watch’s heart rate monitor, plus yet another proprietary Fitbit charging adapter (make sure you don't lose your cable – replacements are £17), and inside the watch case are further sensors. In addition to the usual three-axis accelerometer and gyroscopes, the Ionic has an altimeter so the watch can track the number of staircases you’ve scaled during the day and GLONASS/GPS satellite positioning radios, which should, in theory, improve positional accuracy over regular single GPS devices.
The Fitbit Ionic caps it all with a battery life to put even the best smartwatches in the shade. I’ve been wearing the Ionic for a couple of weeks now and I’ve only had to charge it three times – that’s four to five days per charge. Obviously, if you use the GPS and exercise tracking features more intensively than I have, you’ll need to charge it more frequently. Fitbit states that the watch will last up to ten hours with continuous GPS use, but that's still impressive, especially when you realise the Ionic is continually monitoring your movement and heart rate.
Fitbit’s fitness tracking credentials are second to none and the Ionic takes that to the next level. It’ll track all the usual stuff a Fitbit Charge 2 can, of course, displaying all that in a friendly and accessible manner in the Fitbit app on your smartphone.
It’ll keep tabs on your heart rate during the day and overnight, track your sleep, your steps, floors climbed and if you take it out on a run or a bike ride without your phone it’ll track your speed and distance travelled accurately and plot that on a map within the Fitbit app when you get home.
The GPS tracking is accurate, the heart rate close enough and the rest of the metrics are presented in such a manner that they’re easy to understand and act upon. Better still, the watch's auto-pause mode lets you track only those moments when you're actually moving.
And in terms of exercise types it tracks, that’s pretty comprehensive, too. Full waterproofing means swim-tracking is available here for the first time in one of Fitbit’s smartwatch-style fitness trackers, with the watch keeping tabs on elapsed time, lengths swum and distance.
Plus, you can also ask the Ionic to track cycling, running, treadmill and weights sessions. There’s an interval training mode and a generic “Workout” mode, which tracks your heart rate continually but doesn’t activate the GPS, while the Fitbit Coach app takes you through various workouts, step-by-step, with instructions displayed on-screen.
All good stuff, but what’s great about the Fitbit Ionic isn’t necessarily what it tracks or the data it supplies afterwards – it’s how good it is at picking up on activity automatically. If you forget to select the running mode, for instance, it will detect what you’re doing and activate it automatically, GPS and all.
It’ll do the same if you walk somewhere at a brisk pace, even though there’s no specific walking exercise mode, and when I forgot to hit the Start button on my swim last Saturday morning it worked out what I wanted to do and activated automatically. I had to add a lap because that’s how long it took before recognising what I was doing, but it's still a very useful feature to have. If only it was able to detect stroke types like the Apple Watch now can.
Unfortunately, this is where we get to the slightly more negative things. The big irritation for me is that, once you’ve looked at the summary of your most recent exercise session, then dismissed it, you can’t then look back at that summary again. You can tap to see your Today summary, which shows your activities – steps, heart rate, floors climbed and so on – but for in-depth analysis, you’re forced to check the app.
