Verdict

The call

The clearest difference is rating: E at 5.0 against 320 Guide's 4.6. E also leads on update cadence (weekly vs monthly) and iOS requirement (12.0 vs 14.0.0). 320 Guide's advantage is ratings volume (44 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
