Mizuno brings club fitting to a new level with the Performance Fitting System. Our patented technology quickly measures the five areas of the player's swing: headspeed, tempo, toe down, kick angle, and release factor. This determines one's "Swing DNA" to recommend the perfect shaft and set makeup for your individual swing.
Please note this app is used by Mizuno fitting dealers only, and some features are not available in all countries.
Our redesigned app puts even more knowledge at your fingertips:
- Refined fitting technology with recommendations better tailored to the player's unique swing
- Compare E.I. curves of shafts of any flex or weight showing your personal Bending Profile
- 3D Shaft Chart highlights the science behind fittings like never before
- Build a full set, including Irons, DLRs, Wedges, and Woods
- Simple, intuitive design works well across all platforms
Works great as long as you don’t have a newer iPhone. Mizuno will not fix their app to work with iPhone that has dynamic island. Extremely lazy on their IT department.
Fitting Canceled due to “Sensor Error”
Bill@VGC
The software seems to be stuck with a “Sensor Error” message on the screen. My customer left because Optimizer unable to function properly. Losing a sale is disappointing.I have deleted the app and will reinstall….hoping this will be the solution.When functional….the Optimizer is a great tool.
Really helpful

Use it to calibrate some swings and get clients dialed in for a fitting.
