Using a smartwatch or fitness tracker to detect tempo while running

[potnoodle19]

Most recently I have been trying to do much more cardio in the gym to try and get fit - and I am considering buying a smartwatch or a fitness tracker for heart rate monitering. My phone is quite bulky and I don't like wearing a running armband as it is uncomfortable and gets very sweaty. I was wondering whether if I were to buy a fitness tracker, that spotify running is able to detect running tempo using the fitness tracker rather than the phone itself (so I don't have to set manual tempos before I run, as my tempos tend to change, or I don't have to run with the phone in my hand while I'm sweating buckets) ?

I would also love the ability to run spotify running directly from a fitness tracker and play wirelessly via bluetooth headphones, eliminating the need for me to take my phone into the gym at all, but I don't think that is possible either?

Look forward to your replies. Thanks.

I'm pretty sure it doesn't work with smart watches or fitness trackers yet.

Maybe you should suggest it in the ideas section?
