Verdict
The clearest difference is price: iDatabase at Free against PixelCalc's $2.99. iDatabase also leads on update cadence (fortnightly vs every 3 months) and review sentiment (52% vs 42%). PixelCalc's advantage is in-app purchases (none vs 3) and iOS requirement (11.0 vs 18.6). On ads, monetization model and device support there is nothing between them.
