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.

Your data stays in your Nextcloud. The app works with the KOOK SESSION app for Nextcloud, which must be installed on your server. There is no account with a third-party service, no advertising and no tracking. The app works online only: nothing is stored on the phone except your sign-in details, encrypted with the Android Keystore.
