Email is the fastest way to reach us. To report an error in one calculator, use “Report an error in this calculator” under its Evidence section — it opens an email with the calculator already named.

On the website every calculator is free without limits. In the app, 5 completed calculations a day are free. MedScore Pro is a one-time purchase (no subscription) that removes the daily limit and adds favourites and a calculation history.

Open Settings → “Restore purchase”, signed in with the same Apple ID or Google account you used for the purchase.

Purchases are processed by Apple and Google, so refunds are requested from them:

Tap the unit next to a value (for example mg/dL or µmol/L) to switch it for that value. The default for all values is set in Settings.

No. Values you enter stay on the screen and are never stored or sent. See the privacy policy for everything the app keeps on your device.

Every calculator implements a published score or guideline and shows its sources under “Evidence”. If you think a value or a source is wrong, please tell us.

MedScore reproduces published clinical scoring systems for healthcare professionals and students. It is a reference and educational tool: it does not provide a diagnosis, treatment recommendations or medication dosing, and it is not a substitute for clinical judgement. Always check results against current guidelines.
