## CRSI Rebar Reference Reviews in United States

### *---- "App Doesn’t work"
I paid and the app still doesn’t work.
-- Cuquira1, 2024-10-30

### *---- "Premium Modules Don’t Work"
Had this app for year and development length calculator worked great. Then, I couldn’t access it and could buy another. After buying new phone, I was able to purchase premium app again. But after purchasing, it still doesn’t work
-- Yevla cant find name, 2024-08-09

### *---- "Useless App because you can’t sign in"
The app requires separate account from the web version and if you try to create a sign in at the app then none of the buttons work and you can’t make an account. Giving up after trying so many times.
-- Zeemas, 2024-06-13

### ***-- "Sign-in"
Why would this app start with a sign-in screen? The information it provides to the user does not depend on who that user is. Are they trying to track me? I just choose “guest,” but that is still an extra click before I see what I came for.

Also, the text of that sign-in page overflows to both the left and right sides of my small screen, so you can tell they just tested the app on more capable hardware. Other than those complaints, it performs as advertised.
-- JeffLayman, 2021-10-07

### ***** "Updated to 5 star"
New version fixed problem!
-- dcooper.ce, 2021-03-13

### *---- "Does not work"
Development length calculator does not work. Please fix or provide me a refund
-- rpellbb2, 2021-02-26

### **--- "Lap splice calculator bugs"
All the options for input in the lap splice calculator are blank making this app useless. Please fix it because this feature is a paid one. Thanks.
-- nguyetcres, 2020-07-29

### ***** "CRSI Mobile App"
Great, easy app to have in my pocket for job site visits!!!!!
-- epoxypete, 2019-08-20

### ***** "Great Tool"
This is the official CRSI app !  Must have for anyone working with steel reinforcing bars.
