Army Leader's Book (LB) is a free iPhone application designed to help leaders keep track of important information about their soldiers. With LB, you can easily manage your soldiers' APFT/ACFT scores, weapons, body composition, training, and MedPros dates and data. The app also features sections for tracking absences, appointments, flags, ratings, and more.

LB prioritizes security by utilizing Google's cloud database service, Firestore, which encrypts data both during transit and while stored on the server. Additionally, LB implements additional security rules to ensure that only you can access your data. It is important to obtain permission from your soldiers and have them sign a Privacy Act Statement before inputting their information into LB.

For users who require additional features, LB offers a premium subscription for $1.99 per year. This subscription allows you to upload information via Excel files, download data to PDF format for creating a hard-copy leader's book, and removes ads from the app.

Overall, Army Leader's Book provides a comprehensive solution for leaders to efficiently manage and maintain their soldiers' information, ensuring readiness and effective leadership.
