Verdict

The call

The clearest difference is price: PrayDOS at Free against The Catechism's $4.99. The Catechism's advantage is update cadence (every 5 days vs fortnightly) and chart position (#20 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
