Verdict
The clearest difference is update cadence: J at every 5 weeks against SEMICOM SMART's every 7 months. J also leads on rating (5.0 vs 4.8) and iOS requirement (9.0 vs 14.0). SEMICOM SMART's advantage is ratings volume (19 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
