S Health: Show Min/km and not km/h splits?

[nuff_said5]

Hi all,
I have recently started using S Health for running, paired with my Samsung Gear 3 Frontier.

When it shows split speeds (i.e. speed per km) it shows it in km/h, how do I change the app to show it as min/km?

I know you can manually convert but i would really prefer not to.

Lastly - if this change is not possible - what other app do you recommend that is compatible with the Gear 3?

Thanks
