PRIVATE AND OFFLINE No account and no sign-in. The values you enter stay on your phone and are not saved or sent anywhere. The calculators work without internet. IMPORTANT MedCal is a reference tool. It is not a medical device and does not diagnose or treat any condition. Results do not replace the judgement of a qualified health professional. In an emergency, call 1122 or go to the nearest hospital. The app is free and shows a small banner ad on the home and settings screens only, never on a calculator. Made by HomiLabs.
