The M400 not only tracks your pace and the distance you’ve covered while running, it also works as a 24-hour fitness tracker that counts your steps, calories burned, and how long you slept. The smartwatch will also send you customized goals for training, estimates of how you’ll perform in your next race, suggestions for improvement, and tell you how to navigate back to your starting point if you get lost running in remote locations.
Since the Polar M400 has Bluetooth connectivity, it can sync up with your phone or tablet to give you more detailed statistics and analysis of your performance. You’ll also see more in-depth suggestions on what to do to optimize your next workout. At the core, the M400 is completely focused on fitness. Unlike most smartwatches, it doesn’t try to replace your smartphone, but acts more like a very intelligent fitness tracker.
Polar says the battery will last for 9 hours if you’re using the GPS, but when the GPS is turned off, you can get as much as 24 days of battery life. If that’s true, Polar’s M400 might just be one of the longest-lasting smartwatches — let alone wearables — on the market. It also has a pretty decent design. It certainly looks like a sports watch, but since that’s what most buyers will be using it for anyway, it’s not too big a deal.
The Polar M400 is available in black, white, and now red, for $200 on the company’s website. If you want to monitor your heart rate too, you can buy the H7 HRM chest strap, which pairs with the watch for $50 more.
