Hi Sean,
We will be releasing an update later this month that will support the Apple Watch, and we hope you are as excited as we are! The update will be available when the watch is released later this month.
Thank you for contacting our support team!

Only downside is that their app is $29.99
This is one of the reasons I used to justify to myself the cost of the Watch.
The only drawback I see if the 30 foot range when it's cart path only. Of course for walkers no issue.
for 90% of the people it won't matter if they pick up at 7 iron or an 6 iron..its still going into the woods (myself included)
