Verdict
The clearest difference is price: Khmer Angkor at Free against Engineering AI's $3.99. Khmer Angkor also leads on in-app purchases (none vs 3) and iOS requirement (12.0 vs 26.0). Engineering AI's advantage is update cadence (every 9 days vs every 2 months). On ads and device support there is nothing between them.
