Verdict
The clearest difference is price: CTOT at Free against Density Converter's $1.99. CTOT also leads on update cadence (monthly vs every 38 months). Density Converter's advantage is in-app purchases (none vs 2) and iOS requirement (13.4 vs 16.4). On ads and device support there is nothing between them.
