What it is
The Fix Stack is how a diagnosis becomes actual improvement. It takes your single highest-impact issue and turns it into a tight three-step loop: one body cue to feel, the best-matched drill for your level and the equipment you actually have, and an honest before/after retest to prove whether it worked.
The discipline of "one fix at a time" is deliberate. Improvement comes from focused repetition on the thing that matters most, not from juggling a checklist. By collapsing your whole diagnosis into a single feel, a single drill, and a single test, the Fix Stack removes the paralysis of not knowing what to practice.
It is deterministic, meaning it follows fixed rules, and local-first, meaning it runs on your device. It learns from what worked for you specifically, so its drill matching gets better the more you mark whether a drill helped.
Who it’s for
- Anyone who freezes at "I have ten things to fix — where do I start?"
- Self-coached players who want a concrete, repeatable practice loop
How to take full advantage
A step-by-step guide to getting everything out of Fix Stack.
- 1
Open your priority fix
From a diagnosis, open the Fix Stack for the top-ranked fault. It gives you exactly one thing to work on.
- 2
Feel the body cue
Internalize the single cue before you start hitting — it’s the feeling that drives the change, not a swing thought to overthink.
- 3
Run the matched drill
Do the recommended drill, which is chosen for your level and the gear you have. Then mark whether it helped — this teaches the system what works for you.
- 4
Retest honestly
Re-capture under the same conditions and let the before/after retest show whether the fault actually moved. Only then move to the next fix.
Pro tips
- →Mark every drill verdict (helped / too hard / not relevant) — that feedback is what personalizes future matches.
- →Resist stacking a second fix before retesting the first; the whole point is one lever at a time.
Good to know
Deterministic and local-first — it learns from what worked for you.
- • It surfaces one fix by design — if you want the full fault list, the diagnosis still shows everything.
Frequently asked questions
Why only one fix at a time?
Because focused repetition on the highest-leverage fault produces change; scattering attention across many does not. The Fix Stack enforces focus, then lets you move on once you’ve proven the first fix with a retest.
Does it need an account?
No. The Fix Stack is deterministic and local-first. It works offline and learns from your drill feedback on your device.

Personalized Drill Recommendations
Every diagnosis generates 3–5 sport-specific drills tailored to your exact fault pattern. Each drill includes a YouTube search link so you can immediately find video demonstrations.
Retest — Prove the Change
SwingVantage reminds you when a diagnosed finding is due for a retest, then — after you re-analyze under the same conditions — shows an honest before-and-after read of whether it actually changed.
Player Arc
The story of your improvement over time — the faults that keep coming back, which drills actually worked for you, and honest proof of what each retest changed. It builds with every session.
AI Diagnostic Engine
A rules-based engine compares your data against sport-specific benchmarks and identifies your highest-priority swing fault — ranked by severity, confidence, and impact on performance.
