A portable apparatus for transferring data using proximity wireless connection is presented. The portable apparatus comprises a proximity wireless connection circuitry configured to detect a second apparatus in proximity and communicate reference data to the second apparatus, wherein the reference data causes the second apparatus to fetch and illustrate a user editable configuration template associated with the reference data, and wherein the proximity wireless connection circuitry is further configured to read at least some information of the user editable configuration template from the second apparatus. The portable apparatus further comprises a processing circuitry configured to receive physical activity-related measurement data and to process the data, based at least partly on the information of the user editable configuration template, to a physical activity-related parameter characterizing the physical activity. Furthermore, there is provided a computer program executing the above-mentioned functions of the portable apparatus, and a system comprising the second apparatus.
