Verdict
The clearest difference is rating: Prometheus at 5.0 against Age Clock's 3.1. Prometheus also leads on update cadence (every 3 months vs every 21 months). Age Clock's advantage is ratings volume (10 vs 1) and device support (5 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
