Method
From swing data to a shaft shortlist
Add your session
Upload a supported CSV, or enter the measurements yourself. Club speed is enough to start. The iOS and Android apps also accept Excel.
Set your fitting goal
Pick Distance, Dispersion, or Balanced. The result records that goal, then shows a candidate score and the fit factors for each shaft.
Review your shortlist
Compare the shafts, save the fitting, and share it with one person. Download a PDF when your plan or credit balance allows it, or browse the shop.

The candidate score runs from 0 to 1 and rates that shaft against this session. Overall confidence is a separate percentage for the session itself. A score of 1.00 is not 100% confidence.
These rows are product output from 17 to 20 October 2026, with player details removed. They are a starting shortlist for testing, not a guarantee of distance, dispersion, or scoring, and not a customer review. Names are shown as the app returned them.
Engine
Every result is a ranked shortlist with a short reason for each shaft. Review the factors the app actually shows.
- The goal changes the weights
- Distance, Dispersion, and Balanced each use a fixed mix of flex, weight, launch, spin, and torque. The goal does not add or remove shafts. This is a scoring rule, not a trained model.
- Two numbers, two jobs
- The candidate score is 0 to 1 for that shaft. Overall confidence is a separate percentage for the session, from the shot count and how steady smash factor was.
- Missing data stays missing
- A shaft only lists the factors that result actually has. Estimated spin, including Garmin's calculated spin, is matched more loosely and the session confidence is lower.

Questions
Before you start
How do I start?
Create an account in the app or on the web. A new account includes 3 fitting credits, and no card is required. One credit runs one analysis on pay as you go. Monthly, Annual, and Lifetime plans do not spend credits. Finishing your fitting profile later adds 3 more credits, once.
What if I don't have a launch-monitor file?
Enter the session by hand. Club speed is required. Launch, spin, and the other measurements are optional, and they tighten the shortlist when you have them.
Which launch monitors and file formats are supported?
CSV exports from Garmin Approach R10, GSPro, Rapsodo MLM2PRO, and Square Golf. The iOS and Android apps also accept Excel. TrackMan and FlightScope files are not supported. See the tested monitors
Does ShaftFitters guarantee more distance or a perfect fit?
No. It builds a shortlist from your data so you can decide what is worth testing. Check the options on a launch monitor or with a club fitter before you buy.
How do the fitting scores work?
Each shaft gets a candidate score from 0 to 1. That score blends flex, weight, launch, spin, and torque, using fixed weights for the goal you picked: Distance, Dispersion, or Balanced. Overall confidence is separate. It comes from how many shots you sent and how consistent smash factor was, and it is shown as a percentage with a High, Medium, or Low label. Medium starts at 55%. A Garmin session is marked down because its spin is estimated. A score of 1.00 is not 100% confidence, and this is not a trained model.
What happens when the free credits are used?
On pay as you go, $10 buys 3 more credits. Credits do not expire. You can also move to Monthly at $15 per month, Annual at $75 per year, or Lifetime at $300 once. Those plans include unlimited uploads.
Can I save or share a fitting?
Fittings are saved to the account. Sharing with one person is free and does not spend a credit. Opening a shared fitting, or downloading the PDF, needs a paid plan or a credit balance. The PDF download itself does not spend a credit.
Can I buy equipment in the app?
Yes. The shop sells clubs and gear, checkout runs in the app, and orders ship in the United States from the supplier.
How do I get help with an import?
A rejected file usually means the export is a summary rather than raw shot data, or it is a monitor we do not read yet. Open support
Your next fitting can start with the data you already have.
Add a manual session or a supported file, review the first shortlist, and decide what is worth testing.
