Verdict

The call

The clearest difference is review sentiment: Lambda calculus at 100% against Electromag's 45%. Lambda calculus also leads on price (Free vs $1.99) and iOS requirement (16.0 vs 18.6). Electromag's advantage is rating (5.0 vs 2.5). On ratings volume, ads, in-app purchases and device support there is nothing between them.

Lambda calculus is free to download; Electromag costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Electromag holds the better App Store score, 5.0 against 2.5. Both are backed by a comparable volume of ratings — 2 and 2 respectively. Written reviews complicate that: 45% of Electromag's written reviews are positive against 100% of Lambda calculus's, so the app with the better star average is not the one people write more warmly about.
