Verdict

The call

The clearest difference is review sentiment: E at 83% against Levven Controls's 26%. E also leads on in-app purchases (none vs 1) and update cadence (fortnightly vs every 3 months). Levven Controls's advantage is price (Free vs $14.99) and iOS requirement (18.0 vs 26.0). On ads and device support there is nothing between them.
