Distance apps hand a golfer the tour average for a 7 iron. That number is useless if your 7 iron goes 158 and the chart says 172, and it is worse than useless because you club down and come up short.
The other problem is the course itself. Signal is bad, and nobody is creating an account standing on a tee box.
Log what you carry with each club and the numbers become yours.
Everything runs on the phone, because a course reliably has no bars.
Open it and use it. Nothing to sign up for before it is useful.
It shows the distances you have nothing proven for, so you know what to practice.
