Verdict
The clearest difference is price: DoD Systems Engineering at Free against Army Engineer Guide's $0.99. DoD Systems Engineering also leads on review sentiment (50% vs 33%). Army Engineer Guide's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 26.0). On update cadence, ads and in-app purchases there is nothing between them.
