Skydiving Logbook is a free logbook application designed specifically for skydivers. It allows you to log your jumps with detailed information including jump number, date, DZ, aircraft, gear, jump type, and more. You can even add a diagram to your log. The app also has a feature to allow licensed skydivers to sign entries in your logbook using the touchscreen.

In addition, the app offers a variety of features to help manage your gear, DZs, and aircraft. You can manage your gear components/serial numbers, and set service reminders. You can also manage your DZs, set one as your home DZ, and manage your aircraft with 15 or so built-in aircraft options. The app even has a feature to calculate wing loading, desired canopy size, and extra weight needed to target a desired wing loading.

The app offers an easy-to-use import/export feature for backing up, transferring, and printing your logbook. It also has a logbook history section for entering previous freefall time and number of cutaways. This app is perfect for skydivers of all experience levels.
