The Interval Manager (INTMAN-Mobile Workforce) is a mobile-assisted Utility that replaces the traditional paper-and-pencil strategies to gather fixed c language time-sampled observational information. An initial application that compares INTMAN-Mobile Workforce with the traditional method of paper-and-pencil was presented in this article. Smart Devices were used to run INTMAN-Mobile Workforce data collection application while a Microsoft Windows run using desktop was used to analyse the data. Changed frequencies, durations percent, conditional probabilities, and kappa settlement matrices and values were the analyses carried out. the contrast among INTMAN-Mobile Workforce and the traditional paper-and-pencil technique was primarily based on 5 dimensions: setup time, statistics entry duration, length of inter-observer agreement calculations, accuracy, and price. the outcomes show the efficiency and accurateness of the computer-assisted data collection system over the conventional technique for Time-sampled records.
