Mathias Tschopp's super-useful (and still free) medical calculator MedCalc has been updated.
Version 5.0 adds 3 formulas (target height, pressure gradient, two-way table), a new onscreen numeric keypad on most formulas to ease data input (Finally!), an option to view detailed information in place of the virtual Graffiti area on compatible devices, support for the collapsible input area on Sony devices, and the usual bug fixes.
