## Most critical reviews (6 lowest-rated)

### 1/5 — French size not available

*2025-05-24*

You have to delete and redownload for French and gauge size to appear… so strange!

### 2/5 — Catheter Size

*2025-09-17*

Catheter size disappears after closing the app and requires the app to be deleted and redownloaded.

### 2/5 — Improvements

*2025-05-08*

Would love for it to show cm, not mm. Also I find our team has to delete and redownload a lot to get gauge list to appear

### 3/5 — Inaccurate

*2024-04-18*

CVR calculations on top right = catheter to vein occupancy. There should be an option to change it and should be corrected

### 5/5 — CVR Calc is great

*2024-08-07*

This app helps clinicians to get the correct ratio between catheter and vessel. 
Works great, simple to use and makes it alot easier than having to do that math manually.

### 5/5 — Awesome!

*2019-02-26*

Great app that every Vascular Access Specialist should use to document CVR.
