# eGFR vs CKD

The clearest difference is update cadence: eGFR at fortnightly against CKD's every 5 months. eGFR also leads on ratings volume (4 vs 1). CKD's advantage is rating (5.0 vs 4.8) and iOS requirement (13.0 vs 16.4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

CKD holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 4 and 1 respectively.

eGFR ships an update fortnightly, CKD every 5 months. The most recent releases landed on November 1, 2026 and November 6, 2026 respectively.
