Muster is a readiness tracker built for U.S. Army Reserve soldiers. See where you stand at a glance, know what's due, and get to the right place to fix it — in under a minute. WHAT MUSTER DOES - Tracks your readiness across personnel, security, training, fitness, and medical requirements in one place - Shows clear status at a glance — current, due soon, or overdue - Points you to the exact system and steps to complete each item - Logs what you've done and when, so you always have your own record BUILT FOR THE 0600 GLANCE Muster is designed to answer one question fast: what do I need to take care of? Open it in the parking lot before formation and know in seconds. LEADER MODE Leaders can build a squad or platoon readiness picture without a server or a spreadsheet. Soldiers share their status by QR code; leaders scan to assemble a roster and roll it up the chain. Status moves by QR, soldier to leader — nothing is uploaded anywhere. YOUR DATA STAYS ON YOUR DEVICE Muster stores everything locally on your phone. It has no account, no login, and no server. Your information never leaves your device unless you choose to share your status by QR code. We collect nothing. Muster is an unofficial tool. It is not affiliated with, endorsed by, or a system of record for the U.S. Army or Department of Defense. Always follow your unit's official guidance and systems of record.
