Visual Analog Scale diagnostics in any language

The VAS translator or VAS tool is a means to bridge the language barrier that can arise between a health care worker and a patient. With this app the health worker can adapt the question to the language of the patient. The app does not automatically translate any texts but allows the specialist to add any question in any language that suits his practice. The VAS translator contains a slider indicator that can be used to indicate a value between zero and one hundred. The ruler can be used as a VAS or an NRS scale. VAS stands for Visual Analogue Scale and is frequently used by physicians, specialists, doctors and treatment officers to have the patient indicate a level of pain.
