This is a formation skydiving and indoor FS/VFS timing app. It allows you to tally how much time was spent building different points or flying inters in a matter of a single slowed down playthrough of the round.

Your videos are not uploaded to any servers, this is entirely client side application and can work completely offline, just download the css/html.

Tested in Firefox 120 on Mac OS (works) and Chromium 121 on Mac OS (does not work, video player is gray).
