This paper describes the research and implementation and validation method of a smartphone application that calculates a vertical jump flight time, using the data collected from the accelerometry sensors in a smartphone. To validate the algorithm results, a statistical number of experiments were performed. While recording the experimental data with a commodity smartphone, a bioPlux Research device equipped with a pressure sensor and with a tri-axial accelerometer was also used to estimate the time the user was airborne while jumping, as a golden standard. The pressure sensor was placed in a jump platform built in the laboratory, and a tri-axial accelerometer was placed on the user’s waist. The data collected by this device were compared with data obtained by smartphone in order to validate the algorithm and make the necessary corrections. The research data and the developed application are available for download and further research in a free and public repository.
