Verdict
The clearest difference is rating: just sit at 4.9 against fullmoon's 4.4. just sit also leads on review sentiment (100% vs 78%) and update cadence (every 4 days vs every 10 days). fullmoon's advantage is ratings volume (114 vs 11) and device support (4 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
