We're big fans of the Polar M400 here at Wareable - we gave it a 4 star review back in October - and there's all the more reason to go out and buy one now that notifications have been added to the mix.
The bad news is that it's iOS only for now, but the good news is that all smartphone notifications will appear in your iPhone's Notification Center; that's WhatsApp, Facebook, Instagram, Twitter, the whole shebang.
Full verdict: Check out our Polar M400 review
You can choose whether notifications make a sound or just appear on screen, and there's a handy 'do not disturb' function as well.
Combining a toned-down version of the training features of the heavy-hitting Polar V800 with everyday activity tracking, the M400 is perfect for runners who want a more lifestyle friendly device.
On the fitness side, the multisport-supporting smartwatch offers GPS tracking for accurate run recording but lacks the built in heart-rate monitor of its bigger brother.
The smartwatch skills are available now through the Flowsync portal - just make sure you're running the latest version of both the desktop software and the app.
