Does not work with Apple Watch 6 OS 7.5

I had high hopes for this App. It installed fine. The iPhone app is nice but I was looking for a regatta watch. The iPhone isn’t practical for a small boat. Wish this would work with my Apple Watch… sent an email to support. Waiting for a response.

Getting ready for a regatta, and was psyched to try this thing out. It installed fine on my phone but won’t even appear to allow me to install it on my Apple Watch 4. Don’t think it has been updated for the new watch but it is not disclosed anywhere. Gonna ask for my money back.

Developer Response ,

Ben - we are sorry you are having trouble. This application works fine on all version of the Apple Watch. A possible reason it did not install is if the iOS and watchOS versions were out of sync between your phone and watch. There are other ways to troubleshoot this. Please contact us at support@tack-x.com or through our Facebook page for support.

Doesn’t keep accurate time for starts or elapsed

The watch app loses 20 seconds in 5 minutes. Great if you want to be late for every start and mystified why they aren’t calling OCS on everyone else. iPhone version seems ok.
