The skydiving community has long awaited a powerful and easy-to-use logging solution for skydiving-related activities. FDS began development of FDS Logbook in early 2019 in an attempt to create an elegant way of viewing data from FDS altimeters. In the course of development, we ended up adding significant social media capabilities to the Logbook. We see FDS Logbook as a tool to help unite our tight skydiving community and help one another better understand what we do in the sky. In such a way, we can improve safety in skydiving and have more fun at the same time as augmenting our knowledge. FDS Logbook is in BETA, although it is fully functional. Each FDS Altimeter comes with 365 days of free use of FDS Logbook.
