The green binder, rebuilt for your pocket. Leaders Book is a digital leader's book for Army leaders, from fire team to battery. It keeps your people, your trackers, and your unit's word in one place, and it keeps working in the field with zero signal. YOUR WHOLE UNIT, ONE BOOK Build your structure the way it actually sits: battery or company, platoons, sections, squads, crews. Every Soldier profile carries real rank insignia, duty position, contact info, AFT score, weapons qualifications with dates, medical readiness with due dates, schools, badges, and assigned equipment serial numbers. PROFILES THAT FILL THEMSELVES Point the camera at a printed Soldier Record Brief and watch name, rank, MOS, ETS, and more autofill. You review every field before it saves. Or skip typing entirely: every account has a personal join code, a leader enters it once, and the Soldier lands in the organization with their profile already linked. ONE-TAP PERSTAT Start a check-in and watch the roll-up fill live. Everyone gets one big I'M PRESENT button. Leaders can mark anyone present by hand for verbal or radio accountability, and tap any status box to see names, not just numbers. TRACKERS THAT LAND ON A CALENDAR Leave, duty, taskings with multiple Soldiers, vehicle manifests with driver, TC, and gunner seats, appointments, tests, counseling, flags. Slide a row to set status. Tap it to see everyone on the tasking. Filter the calendar by any element. A FEED YOUR UNIT ACTUALLY READS Post updates and alerts. Tag elements or people. Attach polls or tracked tasks with a live done counter and a remind button. React with any emoji. Pin what matters. Alerts can go through the app, group text, or both. BUILT FOR THE FIELD Prepare for the field pins your whole book to the phone and syncs when you are back. Night vision turns the entire app red so you can read without lighting up your position. Export the whole book to a printable PDF for the CQ desk. CHANGE OF RESPONSIBILITY IN ONE CODE Hand the entire book to the next leader with a one-time code. Move one Soldier with a share code. Move a whole unit at once with an export code. Your data belongs to your unit. No ads, no data sales. Do not store full SSNs, full DoD ID numbers, or classified material. Leaders Book is not a secure communications channel and is not an official U.S. Army or DoD product.

Verdict
The clearest difference is in-app purchases: Leaders Book at none against PMCS Guide's 1. PMCS Guide's advantage is iOS requirement (15.1 vs 18.0). On price, ads and device support there is nothing between them.
