About Underpar Lab

We build tools that make practice count.

Most golfers practice without knowing what actually happened. You hit a bucket of balls, but by the next swing you've already forgotten the last one. The feedback loop — the thing that actually makes you better — is broken.

Shot Trainer fixes that. Set your phone down and every swing is recorded, traced, and analyzed automatically. No buttons, no extra hardware. Just practice, and let the data show you what's working and what isn't.

What we believe

Improvement comes from honest feedback, repeated often. The best practice tool is the one you'll actually use — so we obsess over making it effortless. Prop, practice, review. That's it.

Who we are

Underpar Lab is a small team building software for golfers who care about getting better. Shot Trainer is our first app, and we're just getting started.

Questions, feedback, or ideas? We'd love to hear from you — support@underparlab.com.
