- 📦CkdCalc version 4.0This version enables use not only in Japanese-speaking but also English-speaking countries, and by using the KFRE formula for non-North Americans, it is possible to determine the risk of progression to end-stage renal failure recommended by the KDIGO 2021 CKD guidelines. This allows for referrals to nephrologists, referrals to preventive clinics for renal replacement therapy by a multidisciplinary team, and the timing for selecting renal replacement therapy. Additionally, prognostic prediction formulas specialized for IgA nephropathy help avoid excessive immunosuppressive therapy in low-risk cases, while conversely, it is possible to determine when to initiate aggressive treatment in high-risk cases. Additionally, the new formula for estimating GFR by the 2021 CKD-EPI provides more accurate GFR for all races and people with uneven body types. It is especially useful for patients around GFR 60 with negative urine abnormality and can help prevent overdiagnosis as CKD.… more

Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Medical apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
