Offline CAPI Surveys

RotatorSurvey Mobile interview is the CAPI module of the Rotator platform, designed for surveys that require the use of mobile devices in the field, such as Tablets, Smartphones, celular telephones (cel phones), notebooks or Laptops. This module provides easy-to-use, but powerful interfaces to achieve a high level of efficiency and data quality through the entire data collection process. The process of creating an offline mobile survey with RotatorSurvey, starts with the use of the "Rotator Study Modeler" component, which offers a great flexibility and speed in the design of the interview, its planning and administration. Once the questionnaire has been created, it may be uploaded to the cloud and then downloaded to any mobile device running the Google's Chrome browser. The questionnaire downloaded on the mobile device, mostly HTML and JavaScript code is very readable, easy to use and powerful.
