I wish it will be better

Ive ran more than 6000 km in 4 years with Runtastic PRO.
I had Apple Watch Sport 1 and till OS 3 your app for watch
wasnt as now.
Last week Ive bought AW series 2 but heart rate is mad.
Once it read half rate, once nothing at all.
I hope you fix that and most of all...
I WANT to be free to have a workout, just with my AW2 and no iPhone.
How many weeks you need to let us use your app just wearing an Apple Watch 2 ?
Im sick to use native app and copy results on Runtastic diary
Thanks
