Confused on where to purchase e6 yearly subscription for PC

Hi all,

I would like to purchase the e6 yearly (27 course) subscription for PC to use with my r10. Not sure if I am suppose to buy it in iOS or if I am suppose to go to the Tru golf website?

I noticed it is $200 if I buy thru iOS and it is $300 on Trugolf site but not sure if the $200 version will only allow me to play on iOS?

Thanks,

Roger
