Comments on Calculate by QxMD for Android

★★★★☆ Muhamad Alherk · Feb 27, 2024
Perfect App., I have rated with 4 stars, thanks for adding the both versions of MDRD eGFR. But why you didn't do the same for CKD-EPI, as NICE UK is still recommending CKD-EPI 2009 version
★★★★☆ Muhamad Alherk · Aug 31, 2021
Perfect App., I have rated with 4 stars, as there is wrong in MDRD eGGR calculation. You are using the old formula, which is for non IDMS creatinine methods. Please change and use factor 175 instead of 186, as the majority of methods worldwide are IDMS TRACEABLE now
★★★★★ Ahmed Mohammed Umar · Dec 17, 2021
Very Nice Medical App. I would love that you add FOURNIER'S GANGRENE severity index (FGSI) and Uludag FGSI. Thank you
★★★★☆ deepa ramasamy · Jun 4, 2021
Great app.but please add Cabg + VSR surgery in cardiac surgery.and need to add more co-morbidities for cabg, isolated valve surgeries and aortic surgeries
★★★★★ Mahmoud Dabis · May 13, 2025
Best free medical calculator from Meds cape and 1st of its kind!
★☆☆☆☆ Om Prakash Singh · Jan 17, 2022
Now not opening properly after update... just showing white blank page
★☆☆☆☆ Pako Azhanani Ketlhabanetswe · Sep 5, 2021
Honestly this app has been amazing, but working in a rural hospital I don't always have access to continuous Wi-Fi or internet, and now I can't access the useful information when I need it. Please allow offline use again
★☆☆☆☆ Eduard K · Oct 9, 2021
Why does the app require an Internet connection all the time? I used it abroad and in a plane without the possibility of getting online. Now it's useless for me. I wait a couple of weeks for an update, but if it doesn't change, I will uninstall it.
★☆☆☆☆ Gottipati Pushpak Venkat Chowdary · Nov 22, 2021
It's working fine till the last update. Now it's showing a blank page when I try to open it.
