Verdict
The clearest difference is price: fivelevel at Free against Zulu Time's $0.99. fivelevel also leads on update cadence (every 4 weeks vs every 3 months) and iOS requirement (13.0 vs 17.6). Zulu Time's advantage is ratings volume (2.6K vs 7) and chart position (#57 vs unranked). On rating, ads, in-app purchases and monetization model there is nothing between them.
