## Most critical reviews (7 lowest-rated)

### 1/5 — App crashing

*2021-11-25*

App still crashes on first shot.

### 1/5 — Crashes when receiving shot data

*2021-05-29*

App continues to crash on first or second of the three shots. I have deleted the app and reinstalled and same issue. Please find the bug!

### 1/5 — Crashes on ‘continue to set makeup’

*2020-08-17*

Latest version (8/16/20) crashes when touching ‘continue to set makeup’ when fitting for left handed clubs.  

Generally the promised  functionality is wonderful; but the implementation is horrible.  Buttons don’t work except with multiple touches.  Selected wood shafts don’t show up in the Summary view.  Navigation between iron and wood fitting doesn’t show the top three wood shafts. Hybrid shafts cannot be chosen.

### 3/5 — Fitting Canceled due to “Sensor Error”

*2021-10-02*

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.

### 4/5 — Club fitter

*2023-08-29*

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.

### 4/5 — Really helpful

*2022-10-28*

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

### 5/5 — Great Fitting device

*2021-04-09*

A very cool tool helping make my fittings more informative for the customer while making my job easier.
