I’m guessing it’s an easy fix. It is supposed to add up all the categories but it only sums up the last information added not each of the 6 boxes. ### 5/5 — Important tool *2025-12-25, version 5.4.8* It is extremely helpful to have all of these measuring variables available address the severity of possible diseases. Thank you MDCalc!! ### 4/5 — Make the favorites the default list. *2025-12-14, version 5.4.7* The app is awesome, and a great way to add to my clinical decision-making and justifications. Just for ease of access, though, I would love to have my favorites list as the default list. ### 4/5 — Meld child whites *2025-11-24, version 5.4.7* If the entries are organized like Na creat albumin bill INR rather than them all over would help . ### 5/5 — Excelente *2025-11-13* Aplicativo fácil de utilizar, ferramenta muito útil na prática médica! ### 5/5 — Excellent *2025-11-09, version 5.4.7* I find this app very useful and I tell my students to download it.

Clinical practice for the last 4 years and I still use it. Unless an AI version comes out this is a must have. ### 5/5 — Linda (Ascension) *2025-09-30, version 5.4.6* I really appreciate this App, I use it all the time with my critical patients, Especially my favorite Heart Patients!!!!!

I can use one calculator and when I go back to the main page I can’t access any others. I have to leave the app every time. Very annoying ### 5/5 — Prof Dr Saraf mbbs ms frcs *2025-05-11* 2021 ckd epi creatinine formula pl make it work with mg% & not umol/L ## Most critical reviews (10 lowest-rated) ### 1/5 — Deception *2026-04-18* I fill all fields, but I don’t have any results ( that happened to me with SCORE2 for example) , I have always the same message ( please fill out required fields ) ! **Developer response:** Hello, We apologize for the negative experience.

Best, The MDCalc Team ### 1/5 — Unusable, crashes *2026-03-11, version 5.4.9* It won't open. Ongoing issue with multiple versions, including newest ### 1/5 — Traduction en autres langues *2026-03-05* Mettez aussi en français ### 1/5 — Crashes *2026-01-29, version 5.4.8* Does not open on iPhone despite multiple software updates / app updates ### 1/5 — Unnötiger Anmeldezwang *2024-11-03* Komplett unnötiger Zwang zur Registrierung und Anmeldung. Sonst keine Funktion. App gelöscht. ### 1/5 — UI is trash *2024-01-05, version 5.2.28* 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. ### 1/5 — Good resource, but shouldn’t require registration *2023-12-15, version 5.2.28* 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. ### 1/5 — Broken After Update *2023-10-11, version 5.2.17* 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 ### 1/5 — Not for iOS *2023-08-25* Hardly ever opens on my iPhone ### 1/5 — Not working after update *2023-08-20, version 5.2.11* Constantly crashing after the update. Will show the logo and then crash ## Most praised reviews (10 highest-rated) ### 5/5 — Md cal medical cal *2026-08-10, version 5.4.9* The best advice to follow and look into ### 5/5 — Great tool *2026-08-03, version 5.4.9* Hospital medicine; I use MDCalc all the time ### 5/5 — Tradução *2026-07-28* Ótimo aplicativo só falta ter tradução para português ### 5/5 — FNP *2026-07-06, version 5.4.9* I rely on med calc for calculation support when treating patients and making decisions to treat those who can go either way in treatment. ### 5/5 — NP *2026-06-25, version 5.4.9* I’ve been using this calculator for years. It’s great! ### 5/5 — An absolute must *2026-06-16, version 5.4.9* This is an absolute must for all clinicians. It adds so much depth to your evaluation and charting. ### 5/5 — Favorite medical calculator *2026-06-01, version 5.4.9* MDCalc is the best medical calculator available.
