RCLogbook is an iOS application designed by RC pilot Thomas Willis for RC modelers who need a convenient and effortless logging solution for their RC models and batteries. With RCLogbook, users can easily capture and edit information on flights or races, including total time, location, notes, and average current draw.

One of the key features of RCLogbook is its ability to integrate seamlessly with your modeling activities. The app can travel with you to the flying field, racetrack, or lake, providing a timer that allows you to update your logs as you fly or race your models. It also offers the option to log events manually when you're away from the field.

RCLogbook allows users to keep a detailed log of each flight or race, including duration, notes, location, propeller, style, fuel, and the batteries used. The app automatically tracks the total time on the model, number of flights, and more. The built-in timer is fully integrated with the tracking, supporting count up and down modes and can use voice or musical chimes to alert you when it's time to bring your model back. The timer can be operated through gestures or screen buttons.

In addition to flight and race logs, RCLogbook also tracks battery charge and discharge cycles, resting voltages, internal resistances, discharge durations, charge amounts, and storage charge state. The app automatically updates discharge information at the end of a flight or race and provides battery performance plots to monitor battery health.

RCLogbook also offers features like barcode generation and a built-in barcode scanner for easy selection of batteries and models for events. It also supports maintenance logs and checklists to help users keep their models in top shape.

Overall, RCLogbook is a comprehensive and user-friendly logging solution for RC modelers, offering convenient features and seamless integration with modeling activities.
