Groundwork

Golf is an outcome. Learning is the product.

What it is

A free iOS practice log for one thing: how cleanly you strike the ball. You grade every range ball with a single tap - flush, playable, deep, or top - and Groundwork turns your own grades into honest numbers: every statistic carries its sample size, says how much it can be trusted, and is allowed to say it does not know yet.

No score tracking, no handicap, no leaderboard. Contact is the layer you can actually change at the range, so contact is the only thing measured.

How it treats you

No account. No network. Nothing leaves your phone - the app works at a range with no signal because it never needs one. Your practice history is yours, exportable as a plain JSON file whenever you want it.
