Abstract

This pilot study attempted to determine the validity and reliability of 2 ios ® applications (Measure® and Ruler App®) in measurements of distances. Ten university students aged between 22-23 years old measured 8 arranged distances with 4 lengths in horizontal and vertical lines with the above two applications. They repeated the measurement at least 1 week apart. Both applications had high inter and intra reliability (ICC = 0.94-1.00) The percentages of error of both application are 3.47-9.36%. No differences were shown between the measurement in horizontal and vertical directions. When the arranged distance was longer than the percentage of errors became higher. Ruler App® tended to have less percentages of error when compared to that of Measure® in long distance measurements.
