Verdict
The clearest difference is review sentiment: Dr. Osman at 100% against RBClass's 26%. Dr. Osman also leads on rating (5.0 vs 3.1) and monetization model (free vs free with in-app purchases). RBClass's advantage is ratings volume (336 vs 2). On price, ads, in-app purchases and device support there is nothing between them.
