When I started working towards my A License (almost there), I looked at my Garmin fitness tracker and thought it would be cool if I could use it to log my skydives and do something with it. I ended up building a rudimentary logbook application around it, but I still mainly use it to import my skydive data recorded with my fitness tracker and export to a KML file I could look at in Google Earth. It’s called YANSL (Yet Another Skydiving Log), It’s at the point I feel I can share it in very beta form. I’m sure the fact I’m new to the sport (and a bit naïve) may show through, so suggestions welcome if you try it.
Right now, it imports TCX files from Garmin devices that have a GPS on board. I use a Vivoactive HR tracker I’ve had for over a year. It’s a low fidelity solution (hope to upgrade to a Fenix 5 or 5+ someday). If you can get a TCX file from other trackers (I think you can get TCX from Fitbit devices), feel free to send me an example jump recording and I can make modifications required to support that import.
Here’s a link to the installer (Windows only at this point, I tested on Windows 7 and 10):

Here’s a link to some videos going over basic usage (I may up the volume and regenerate them).

I still have work to do on it. If there are useful additions/modifications, please let me know via a reply post or message. It would not be hard to produce a version compatible with Macs. I haven’t decided whether or not to release source code at some point in the future.

Finally, here are some screenshots from one of my jumps. I also included a graph I built with Excel from the csv export feature of the logbook. Shows pulse rates for student jump 1, 2, and 10.
Enjoy!
