Read full descriptionHide full description
As an important parameter for assessing kidney function, the glomerular filtration rate, or GFR, is widely used. With the eGFR app, you can calculate an estimated glomerular filtration rate (eGFR) based on serum creatinine. For children and adolescents up to 18 years of age, the Schwartz formula is available. For adults, the CKD-EPI, MDRD and Cockcroft-Gault formulas can be used depending on the desired calculation. In addition, the app provides background information on the individual formulas, guidance on the interpretation of GFR values, and information on risk reduction. The eGFR app is intended solely for calculation and informational purposes and does not replace medical diagnosis, advice or treatment. Medical decisions should not be made solely on the basis of the information provided in the app. In case of health concerns, abnormal values, or before making medical decisions, medical advice should be sought.

Verdict
The clearest difference is update cadence: eGFR at fortnightly against iChoose Kidney's every 14 months. eGFR also leads on review sentiment (100% vs 86%). iChoose Kidney's advantage is rating (5.0 vs 4.8). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
iChoose Kidney holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 4 and 4 respectively. Written reviews complicate that: 86% of iChoose Kidney's written reviews are positive against 100% of eGFR's, so the app with the better star average is not the one people write more warmly about.
iChoose Kidney ships an update every 14 months, eGFR fortnightly. The most recent releases landed on October 21, 2026 and October 29, 2026 respectively.
