Verdict
The clearest difference is update cadence: BJJ Notes at every 4 days against SENSAY's every 3 weeks. BJJ Notes also leads on ratings volume (178 vs 12). SENSAY's advantage is rating (5.0 vs 4.7) and review sentiment (100% vs 87%). On price, ads, in-app purchases and monetization model there is nothing between them.
