Verdict
The clearest difference is price: Engineered Per4mance at Free against Aikido Encyclopedia's $9.99. Engineered Per4mance also leads on update cadence (every 46 months vs every 97 months). Aikido Encyclopedia's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15). On in-app purchases and device support there is nothing between them.
