Verdict
The clearest difference is price: Rhythm at Free against Strongbox Zero's $99.99. Rhythm also leads on rating (5.0 vs 4.3) and review sentiment (100% vs 75%). Strongbox Zero's advantage is update cadence (every 2 weeks vs every 8 months) and ratings volume (21 vs 3). On ads and in-app purchases there is nothing between them.
