Verdict
The clearest difference is price: Crypt Prices at Free against XLR8's $4.99. Crypt Prices also leads on rating (5.0 vs 2.0) and update cadence (every 6 days vs every 7 months). XLR8's advantage is ratings volume (168 vs 2) and chart position (#129 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.
