When Fitbit launched its first true smartwatch last year, it had something to prove. The company had just bought beloved smartwatch pioneer Pebble, and up till then had struggled to produce a wearable with a proper operating system. So it's no surprise that the Ionic was stuffed full of features. It not only tracks a comprehensive range of fitness metrics and provides onscreen workout tutorials, but also stores your music, streams to Bluetooth headphones, runs third-party apps and makes contactless payments. It even has a blood-oxygen sensor just waiting for the company to turn it on (but right now is completely useless).

It's also not a surprise, then, that the Ionic wasn't cheap. While $300 isn't much compared to the Apple Watch and Samsung's Gear Sport, it might put off people who are fitness novices looking for a simpler device. The Ionic also didn't look like a regular watch, thanks to its hexagonal design that screams "Fitbit."
