Medicalcul is a free medical calculator application for Android devices. It allows you to calculate various scores and formulas including creatinine clearance, Apgar score, and burn surface area. The complete list of scores and formulas can be found on the developer's website. Once installed, the app prompts you to update the data from the website to use it offline. The app checks for updates regularly and notifies you if a new update is available. You can choose to update the data when you have a Wi-Fi connection to save cellular data usage.

You can also add new scores or formulas to the app by contacting the developer. If you have any references for new additions, you can send them to the developer to speed up the research process. However, this app is only available in French. Users in the Maghreb region (Morocco, Algeria, Tunisia) may face difficulty in importing data from the servers due to internet provider blacklisting issues.

Note that Samsung mobile users may encounter a bug that prevents them from entering decimal numbers, but the app provides a workaround by using the right icon in the shortcut bar to enter the decimal point.
