Infiltration is the process in which water penetrates the soil surface. The infiltration rate initially high and becomes constant over time is called the basic infiltration velocity (VIB), which is very important for several areas, and is therefore based on the design of irrigation systems, as well as planning actions that minimize environmental impacts caused by erosion. To determine the VIB, the double-ring infiltrometer method is usually used, registering the water level values with a ruler and then adjusting the data on a computer using mathematical models. The objective of this work was the construction of a mobile application compatible with Android system, which can aid in the data acquisition process. Developed in the Thunkable platform, the application called TEdI allows the user to annotate the ruler values quickly and interactively, at the end calculating the parameters of cumulative infiltration and infiltration velocity versus time from the empirical model of Kostiakov (1932). The validation tests showed that the parameters calculated by the TEdI are the same as those obtained in the literature.
