Tempo Line is a free putting tempo trainer designed to help golfers build better rhythm, distance control, and consistency on the greens. Set your tempo and backswing-to-downswing ratio, then follow synchronized visual and audio cues while you practice. I built Tempo Line because putting tempo has been one of the simplest things I’ve seen help golfers control distance more consistently. I’ve spent most of my life around golf, first as a competitive player and now as a coach. Over the years, I kept seeing golfers struggle with distance control, but the tools available to train tempo were often expensive, complicated, or inaccessible. So I decided to build something simpler. Tempo Line is my small way of giving back to a game that has given me so much. I want more golfers to have access to useful practice tools without needing to buy another expensive training aid. That’s why Tempo Line is free. Features include: • Adjustable putting tempo • Custom backswing-to-downswing ratios • Synchronized visual and audio cues • Adjustable stroke length • Saved tempo profiles • Continuous practice mode Whether you’re practicing at home or on the putting green, Tempo Line is designed to make tempo training simple, accessible, and easy to use. I hope it helps you enjoy putting a little more.
