KOOK SESSION is a logbook for surfers, wingfoilers and other water sports lovers. Log every session with its conditions, keep track of your spots and your quiver, and learn from your own statistics. <b>Your data stays in your Nextcloud.</b> The app works with the KOOK SESSION app for Nextcloud, which must be installed on your server.
