Here comes a description of the GPSLogIt-app for Android smart phones (the promo-version is free and works until 15.07.2018). For online transmission a SIM-card and a data-rate are required of course. An Aqua pac is also needed and the smart phone must not be carried under the wetsuit, but on the upper arm and should have free view of the sky.
Online ranking is available on http://www.gps-speed.com/upload/TrackSpeed.php
the DEFI 500m results are visible without further settings.

and switch on online tracking, put in your sail number and spot name (minimum speed should be set to 20knots, this value is used to determine the category-speeds and 50% of this value (10knots) is the minimum speed used for the online transmission of the data to save data volume, the zoom category is for display purposes only), then click OK:
4. before going on the water, start the GPSLogIt-App, start the GPS service on you smart phone, verify a valid GPS-fix by checking displayed time and number of tracked satellites, then click START RECORDING to save the GPS-data to the smart phone memory as a back-up (GPSLogIt-folder)(optionally select the zoom-category for better visibility of the zoom-category on the water), put the smart phone into your Aqua pac and don't touch any buttons or the screen anymore:
