Rocket Logs allows users to create and manage a library of all of their hobby rocket models, from low-power model rockets to high-power rockets. Users can input important details like ejection charge sizes, weight, diameter, length, and more, with easy-to-reference info for filling out flight cards or preparing rockets for flight. In addition, Rocket Logs allows you to log flights of your rockets down to altitudes, location, landing coordinates, and more. Live-updating analytics allow you to see how many flights you have, your highest flight, fastest flight, most-flown rocket, most-visited launch sites, overall total impulse, and more via the stats page. It's a simple, no-login-required, easy-to-use app that anyone can learn to use in minutes. In addition, advanced flight features, such as details of research motors, can be enabled for advanced data logging and referencing. Handy tools include inventory, a BP calculator, and an editable checklist that you can export and share with your team to ensure everyone is on the same page for a launch. No logins, no ads, no internet connection required. Even the most remote launch sites will not affect your ability to reference the Rocket Logs app. However, app data is fully exportable for remote backups. So, even if you lose your device, you'll be able to restore your saved data on a separate device so long as you've previously saved and exported it.
