POLAR A370

Committing to a fitness tracker is no easy business. It’s a very personal relationship after all, full of intimacy and day-long skin contact. Luckily, Polar’s latest band has a Tinder bio to turn heads – something like this: ‘Finnish fitness instructor, enjoys all-day heart-rate tracking, particularly during exercise, and is now even better at night thanks to weekly sleep feedback and ratings.’ That might sound a little bit creepy, but there’s a good chance the A370’s updated wardrobe of colours will still tempt you to swipe right ahead of the Garmin Vivosmart HR. £170 / polar.com
