A vírgula entre os números não sai! (,) e o cálculo sai errado ficou péssimo ### 1/5 — Error *2021-09-30* We can’t introduce decimals in creatinine data!!! It’s a bug?? ### 1/5 — Utterly useless unlike the calculator on their website. *2021-06-04* I need - no, REQUIRE - a GFR calculator that lets me individualize results to my patient’s individual height and weight. Too many of my patients are way off of ‘standard’ parameters for that to make sense. I had an ancient app that would do this but it no longer works on the current iOS upgrade. I was hoping this app would do so since the cGFR calculator on their website has that as an option. No such luck - and that makes this app useless to me. It was removed immediately after downloading. ### 3/5 — eGFR but no BSA *2022-05-03* This gives you the current 2021 CKD-EPI calculator, however, it does not include the ability to factor in BSA (body surface area - height/weight). The National Kidney Foundation web site has the 2021 calculator with the ability to include BSA. If you do not factor in BSA, you may get a less precise eGFR value. Most national labs also do not factor in BSA, so you might have a conversation with your physician to see her/his thoughts. Just accepting the basic CKD-EPI 2021 formula, may place you in a GFR category and ACR category, you do not deserve. The discussion within this app notes the necessity to factor in BSA to the CKD-EPI 2021 equation, but the equation included with this app does not allow this option. ### 3/5 — Não é possível digitar o valor correto da creatinina e outros *2021-09-27* Pelo no iPhone com iOS 15 , não é possível digitar o valor numérico correto , apenas inteiros ( creatinina 1.5, digita-se apenas 15 ) , gerando cálculos incorretos ### 3/5 — Confusion *2020-12-09* Just clear when we select male/female and black/other the grey option is selected one or the white one? ### 3/5 — Nurse *2019-08-14* Very handy, but there is a flaw that must be addressed. The race and sex fields change when they should not. Tap on “male” for example and tap on on it a second, third, fourth time. Why does it change back and forth and back and forth? Please fix that behavior. Thanks. ### 3/5 — Not bad *2016-10-30* Useful app, but due to the colours used on the slider switches for male/female and black/other it's difficult to see what option you've actually picked. ### 5/5 — Help *2021-09-28* We can’t introduce the coma in creatinine data. ### 5/5 — Excellente *2019-05-03* La plus simple d’usage et très propédeutique . Un référence ## Most praised reviews (7 highest-rated) ### 5/5 — CKD pt + former Med Professional *2017-10-30* I wish I’d known about this several years ago-it would have saved a few grey hairs. I’m 57, a former RN-Paramedic who had to leave Medical School in my final year due to growing health issues related to my genetic disorder, nail-patella syndrome. I (and mySon) were also born with just 1, affected kidney. It wasn’t until the last two years that the proteinuria and overall function began to decline. Because I’m not a transplant candidate, we’re keeping an extremely close eye on everything. Thank you for making this available-AND for everything else you guys do to help patients like myself!! PS I sent the link to this app to my primary & nephro -neither of whom had been previously aware of it. ### 5/5 — Great app! *2016-02-10* Use this app everyday. Only wish you had a Apple Watch companion. ### 5/5 — Just what I need *2013-08-28* Great app and useful for me as a student pharmacist! ### 5/5 — Brief &easy *2012-10-09* Thanks.brief&easy to use. ### 5/5 — Everyone in internal medicine should have this app *2012-03-21* Simple and accurate way to calculate GFR, recommended! ### 5/5 — Fantastic app! *2011-12-26* Worked flawlessly, thank you. ### 5/5 — Clinical director *2011-12-26* Found information extremely helpful. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
