Verdict
The clearest difference is in-app purchases: Revolution Prep at none against OnePrep's 24. Revolution Prep also leads on ads (none vs shown) and review sentiment (63% vs 41%). OnePrep's advantage is update cadence (every 5 days vs every 3 months). On price, rating, ratings volume and device support there is nothing between them.
