Verdict

The call

The clearest difference is rating: Fourby at 4.0 against 3pLevel Pro's 3.5. Fourby also leads on price ($1.99 vs $4.99) and iOS requirement (13.6 vs 17.6). 3pLevel Pro's advantage is update cadence (weekly vs every 26 months) and review sentiment (100% vs 75%). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
