The TomTom Spark Cardio + Music is a fitness tracker for just about everyone: Bicyclists, gym rats, runners, and swimmers can all record their workouts and monitor their heart rates with it. But for $249.99, you're paying for more than just the ability to track your trip to the gym—you're also getting the ability to listen to music during your workout without your phone nearby. In addition to a large monochrome display, a lightweight design, and good battery life, the Spark has local storage for your favorite tunes. It's a solid choice if you're looking to seamlessly incorporate music into your workout, though our top activity tracker is still the Fitbit Surge ($228.38 at Amazon)  for its robust companion app and its ability to deliver messages and notifications from your smartphone.

Does that matter much? Well, it’s a telling symptom of the Spark’s insecurity. The app and abilities of the watch paint it as an all-singing ally – including cadence sensor pairing for cyclists, and swim-tracking for water paddlers. But the watch is only truly consistent – and, in fact, addictively usable – as a standalone sleep and daily activity tracker. Enough data is displayed on the device itself to render the app a necessity only for data-driven sportsters, yet the hardware is just too clunky to appeal to such number junkies. Additionally, the Spark is too complex and inefficient a wrist-wrapper to make sense as a simpler sensor of steps and snoozes – with detailed training modes, tracking and tunes, as well as exports to the likes of RunKeeper and Strava. This means the features supposed to make the Spark special are sufficiently unstable as to render them superfluous, leaving TomTom’s ticker neither a jack of all tracking trades, nor a master of one.

There's nothing like hearing the Rocky theme to get your blood pumping. But for several years now, I haven't listened to music while running. Why? I didn't feel like carrying an extra gadget with me. I got a GPS watch so I wouldn't have to bring my iPhone when I went out for those 10-mile jaunts.

Stream music from watch to headphones; Small; slim design; Easy to read outdoors

Annoying charger; Difficult to load music; Poorly designed app; Shorter battery life than competition

TomTom has diverged from personal navigation, seeing the company embrace sports devices in recent years. After an initial partnership with Nike, it stepped out on its own with the Multi-Sport and Multi-Sport Cardio sportswatches, the predecessors to this latest device, the Spark.

Plenty of features; good GPS and heart rate tracking performance; easy to navigate

Music is a little fiddly; dependency on a computer feels dated

Great monitor for a range of activities in and out of the gym. Effective GPS and heart-rate monitor. Not cheap, but purchased in the sale, so happy!

I I'm love with this device it tracks all gym classes brilliantly works with my I phone records run and tracks my routes gives my splits pace how fast my strides were blows the other companies out of the water brilliant Tom Tom with promotion with free headphones sweeten the deal for me great...

Great product.Excellent delivery

Simply the best sport watch you can get! It's got everything: wrist cardio, music, daily trackers (heart rate, steps, calories), multi sport functions and more. It is light, cool, and above all the battery lasts a whole week with average usage.
