Verdict
The clearest difference is review sentiment: SIM at 43% against CAMMUS's 0%. SIM also leads on rating (4.6 vs 2.1) and ratings volume (445 vs 8). CAMMUS's advantage is in-app purchases (none vs 24) and iOS requirement (12.0 vs 15.0). On price, update cadence, ads and device support there is nothing between them.
