The improvement loop
How one fix becomes a better swing
Most swing tools hand you a wall of numbers. SwingVantage hands you a decision — and closes the loop.
Problem
Something's off — slice, mishits, lost pace.
Diagnosis
Upload one swing. Coaching rules rank faults by impact.
Fix
One priority fix — with evidence and confidence.
Practice
Three drills, a 7-day plan, daily tasks.
Retest
Re-upload. Measure the change — or adjust.
Why one fix
Ten tips break a swing. One fix builds it.
One priority fix
Not ten swing thoughts. The single highest-impact issue, ranked by evidence from your own footage.
Drills that match
Three drills tied directly to your fix, with clear reps and how-to — not a generic library.
A retest that proves it
The 7-day plan ends in a retest, so you see the change in your numbers — or adjust the plan.

A decision, not a wall of numbers
One fix
Your highest-impact fault — ranked by how often and how clearly it shows up.
Confidence
Every claim carries a level: High, Moderate, or Low — and an honest note on limits.
Drills + plan
Three matched drills and a 7-day practice plan, ending in a retest day.
What it can't know
Grip pressure, injury history, game-day pressure — honestly listed every time.
Drills tied to your fix
Estimates are heuristic and improve with video quality. SwingVantage pairs with a coach — it doesn’t replace one. It never gives medical advice.
