Verdict
The clearest difference is price: DoD Systems Engineering at Free against Religion Encyclopedia's $1.99. DoD Systems Engineering also leads on update cadence (every 5 months vs every 46 months). Religion Encyclopedia's advantage is device support (3 vs 1) and iOS requirement (11.0 vs 26.0). On ads and in-app purchases there is nothing between them.
