Upload a photo of a swing analyzer screen (Trackman and the like) and we'll read the club and ball data to point out problems that come from your current driver and shaft. The screen below is filled with example data — upload a photo or enter the numbers yourself and it switches to your real analysis.
We keep your history under your phone number and a 4-digit PIN you choose. Enter the same number and PIN next time and your past results come back.

No launch monitor screen? That's fine. If you know your usual driver distance, you can start. We don't ask your age or weight — they don't decide shaft specs.
Enter your driver distance.
Total distance — carry plus roll, on a normal day rather than your best one.
If you know them, this way is more accurate. Enter the values you saw on GOLFZON or Trackman.
Pick your recent round average, not your best. It feeds into how forgiving the recommended shafts are.
Pick how your ball usually flies.
You don't have to know. If you do, we can compare it — "heavier than now" or "lighter than now".
Enter your usual driver distance.
Photograph your swing result screen like the image below and upload it. One photo per swing, up to five. The clearer the numbers, the more accurate the result.
No photos, or the analysis isn't working? ·
You can edit the extracted values freely. Some devices label clubhead speed as "club speed" — it's the same number. Spin loft is calculated automatically from dynamic loft and angle of attack.
The table is wider than the screen — swipe sideways for the rest of the shots.
Select, in order, the clubs you used for the shot results you just uploaded. If you're not sure about something, choose "Other (not sure)" and move on.
We take your five-swing averages, your current club specs, and the concerns you picked in step 3, and narrow the catalog down to the three shafts that fit best.
What goes into it — four things: your current club specs, your five-swing averages, the "concerns" you picked in step 3, and the "average score level" you choose below.
What the score level does — the higher the handicap, the more weight we give to forgiving, easy-launching profiles and lighter weights; the lower the handicap, the more weight we give to lower-spin, control-oriented profiles and steadier weights. What your actual swing data calls for comes first; this is an adjustment layered on top of it.
The pentagon chart — it compares your current specs (blue line) with the change you could expect after switching to that shaft (orange line) across five measures.
The three boxes below it — the same amount of change converted into an expected stroke change over 18 holes, weighted by course type.
Both numbers are reference estimates and can shift with how the head and your swing actually match up, with course management, with putting, and so on.
This reflects the tendency for the same improvement to save more strokes at a higher handicap. Change the level and the expected strokes by course update with it.
This compares you with the general fitting guidelines for your club speed range. The actual optimum can differ with ball flight optimization data and your own characteristics.
Working from the data and specs above, this lays out priorities, causes, directions for improvement, and which way to go on shafts and heads, in sentences. Unlike the rule-based check, this part is written by AI, so the wording can vary a little even with the same data.
