Verdict
The clearest difference is review sentiment: U at 100% against BLEDIM's 23%. U also leads on rating (3.7 vs 2.0) and update cadence (every 3 weeks vs every 2 months). BLEDIM's advantage is ratings volume (715 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.
