If you want a straightforward visual representation of how hard you’re working, look to Instabeat, which sits on your existing goggles. It measures heart rate from your temple and uses coloured LED lights projected on to your goggle lens to show what effort you’re expending.
Inside the companion app you can pore over heart-rate analytics, get insights into lap counts and stroke type, and also see rest and workout intervals. It’s been a long road for Instabeat to get its swimming wearable out for the masses, having completed its crowdfunding campaign almost six years ago. They cost $249 (£200) from instabeat.com.by
