Verdict
The clearest difference is review sentiment: CERV at 100% against MySolArk's 12%. CERV also leads on rating (5.0 vs 2.0) and iOS requirement (10.0 vs 12.0). MySolArk's advantage is ratings volume (123 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.
