Most golfers don't improve too slowly because they practice too little. They improve too slowly because they train in a way that prevents skill from transferring to the course. Loop fixes the training. Not the swing. Constraint-based practice. No sensors. No equipment. Just your phone. Most practice is instruction-based: watch a video, copy a position, repeat a drill. It feels productive. It rarely transfers. Loop is built on a different model. Each drill gives you a specific constraint — a condition that forces your brain and body to find a solution. That's how skill forms. That's what holds up on the course, under pressure, when it counts. Driven by your data. Not your best guess. Log your rounds hole by hole — fairway, GIR, putts, strokes. One screen per hole, simple taps. Loop scores your putting, approach, and driving — and identifies where you're actually losing shots. Every session is built around your biggest leaks. No technique tips. Drills are assigned, not browsed. Loop tells you what to train. You train it. Who it's for. Loop is built for independent golfers who've already tried tips, YouTube, and the occasional lesson — and hit diminishing returns. Practicing alone, wanting to improve without thinking about their swing more. If that's you, Loop will feel like a relief. If you're looking for swing fixes or technique content, this isn't it.
