Verdict

The call

The clearest difference is price: Electromagnetic Theory Quiz at Free against Electromag's $1.99. Electromagnetic Theory Quiz also leads on update cadence (every 2 weeks vs every 9 months) and iOS requirement (12.0 vs 18.6). Electromag's advantage is in-app purchases (none vs 7) and ads (none vs shown). On rating, ratings volume and device support there is nothing between them.
