Navigation company TomTom has delivered a new line of wearable fitness trackers, offering new devices including one that capitalizes on the company’s expertise in GPS and map technology. The devices aren't yet available for purchase, but those interested can sign up on the company’s website to be alerted the moment they are released.

There are three wristworn devices in the line: The TomTom Touch, which can measure both heart rate and body composition all day; the TomTom Adventurer, a “rugged watch” with all of the features of the company’s earlier iteration Spark 3, plus a built-in barometer; and the TomTom Spark 3, a GPS-enabled fitness watch that uses route exploration features so users can explore new places.

“TomTom once again stands out in the wearables market by offering unique feature-rich products at competitive prices, leveraging our heritage in GPS and map technology,” Jocelyn Vigreux, President of TomTom said in a statement. “The line of products that launched today is well-designed, versatile and smart, packed with disruptive innovation that will inspire fitness enthusiasts.”

The route exploration function is perhaps the most unique, and comes in both the Spark 3 and Adventurer. The Spark 3 enables users to upload up to 15 routes from their TomTom MySports apps and platforms such as Strava. Every time they set out on a new path, their GPS trace is displayed on the watch, preventing people from getting lost on new trails. The Spark 3 also has the ability to store up to 500 songs transferred from iTunes or Windows Media Player, and comes with wireless Bluetooth headphones.

The Adventurer is made specifically for those who prefer to be active outside including hikers, trail runners and skiers. The barometer, compass, heart rate monitor, on-board music player and additional dedicated sports modes can that can automatically detect which activity the user is doing. It can also detect ski slope runs and provide altitude for ascent and descent metrics. 

TomTom's move from GPSes into fitness wearables is a natural one that mirrors that of Garmin, which has been in the fitness wearable space for a little while now. Garmin launched its latest device, the Forerunner 35, yesterday. It's a GPS-enabled running watch with a built-in heart rate sensor that allows runners to monitor their heart rate 24/7 without a chest strap.
