Verdict
The clearest difference is in-app purchases: SFD at none against Dungeon Within's 13. SFD also leads on review sentiment (86% vs 69%) and price ($4.99 vs $5.99). Dungeon Within's advantage is update cadence (every 2 days vs fortnightly) and ratings volume (474 vs 8). On rating, ads, monetization model and device support there is nothing between them.
