Verdict
The clearest difference is in-app purchases: Rock Mapper at none against LiquidText's 13. Rock Mapper also leads on rating (5.0 vs 4.6) and update cadence (every 5 days vs every 2 weeks). LiquidText's advantage is ratings volume (6.4K vs 1) and device support (3 vs 1). On price, ads and monetization model there is nothing between them.
