The clearest difference is review sentiment: Singularity at 100% against Just Blocks's 24%. Singularity also leads on rating (5.0 vs 4.2) and update cadence (every 5 days vs monthly). Just Blocks's advantage is ratings volume (3.1K vs 1) and iOS requirement (12.5 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
