Verdict

The call

The clearest difference is in-app purchases: Barcode Dungeon at none against Dark Slayer's 8. Barcode Dungeon also leads on ads (none vs shown) and update cadence (every 3 days vs every 9 days). Dark Slayer's advantage is iOS requirement (15.0 vs 17.0). On price and device support there is nothing between them.
