## MDCalc Medical Calculator Reviews in United States

### ***** "Good"
Good
-- Rose19474, 2024-12-21

### ***** "Essential for Clinicians"
Wonderful point of care tool that never fails to help during shift when I need it.
-- EmergencyMed7, 2024-12-18

### *---- "UI is trash"
The interface continues to be atrocious and I’m not sure why this hasn’t been addressed. The tap targets are small and invisible. There is no button to rapidly move to the next field for entry. If you need to change the contents of a field in which you’ve already entered a value, god help you and you’re probably better off force quitting the app and starting over. Oh and it defaults to imperial measurements.
-- Jordan Schooler, 2024-01-05

### *---- "Good resource, but shouldn’t require registration"
MDCalc is overall an incredibly valuable resource, but the reason I’m rating the app 1 star is due to the mandatory registration. As a result I use the website instead, which does not require registration.
-- hyderali91, 2023-12-15

### ***-- "Could be better"
Great resource, but user experience could be improved to reduce unnecessary taps. For example, add support for gestures and/or keyboard button to advance to next/previous field. Also, needs setting to make Favorites the default view rather than always starting with Popular.
-- ekrub, 2023-12-10

### *---- "Broken After Update"
Basically unusable after they added a mandatory log in. Every time I open it it spins and it takes more time to load the app than it does to access the same page through my browser. I would love this to be fixed as it was a daily app for me previously
-- gtrghytfh, 2023-10-11

### **--- "Wish I didn’t update"
Always loved this app, had lots of “favorite” pages saved. After new update I had to create an account (annoying but fine, given the free service they provide) but I lost all the favorites I saved! Should have found a way to retain this with the update!
-- Joeyo, 2023-08-28

### *---- "Not working after update"
Constantly crashing after the update. Will show the logo and then crash
-- MJ809, 2023-08-20

### **--- "Used to be good"
Crashes 90% of the time now. Pretty much unusable.
-- esesksks, 2023-08-19

### *---- "App no longer working"
I’m not sure if the new update is not compatible with my iOS but the app was working up until a week ago. Now I am unable to access the app at all, it opens and then immediately crashes. I’ve tried deleting and re-downloading but I’m still having the same issue. Is there anything that can be done to resolve this?
-- k123446k, 2023-08-12

### *---- "App malfunction"
I downloaded the most updated version of the app on my iPhone recently and now it won’t even open. The app just shutting down before it loads. It’s a huge bummer. I used to use this app everyday in internal medicine clinic
-- Melanie Lynn 💖, 2023-08-04

### **--- "Cannot use after update"
I loved this app until it quit working over the weekend during my shift:( I see there was an update which must not be compatible with my iPhone? Help is appreciated.
-- JanSensei, 2023-08-02

### **--- "Unable to sign up"
I am currently in clinicals for my FNP and my preceptor uses this app frequently but I can’t sign up because it requires you input your school and my University isn’t listed. Is there a work around for this? I would love to use this app as it is quite useful in the day to day workings as a FNP and has been so helpful but I can’t use it because of that one requirement.
-- Future FNP!, 2023-07-12

### *---- "Mandatory Account"
Please get rid of mandatory account to access app which does not exist through online browser. Until then will leave as 1 star review.
-- baylorbear9696, 2023-06-19

### ***** "Site Crash"
App is asking me to either log in or sign up.
Cannot do either.  My e mail and previous password both rejected.  Please fix..
Thank you!
-- BiancMD, 2023-06-13

### **--- "Password"
Why do I have to create an account with a password to use your calculator. I already have enough accounts. Who made this decision?
-- Mets4Meatloaf, 2023-06-12

### *---- "Don’t fix what isn’t broken"
Forced to make an account after 5 years of use. Lost all of my saved equations.
-- mcomer09, 2023-06-11

### ***** "Excellent Quick Resourse"
Love using this app as it lets me find what I need fast to calculate all kinds of thing, understand a coma score assigned a patient in the ED, BSA calculation for chemotherapy, Heart scans …
-- Alamosa mom, 2023-03-26

### ***-- "No alphabetical lists?"
It’s hard to criticize the GOAT app for medical students, but they should really make it so the drop down menu for state and specialty are in alphabetical order. Otherwise, amazing app!
-- queenfan66, 2023-03-20

### ***** "Exactly what you want"
The ability to favorite items is key. SUCH a wide range of things too. Thank you, MDCalc!!
-- youngadult3, 2023-03-10
