Verdict
The clearest difference is in-app purchases: MUST STUDENT at none against Matrix Operations's 1. MUST STUDENT also leads on ads (none vs shown) and rating (5.0 vs 4.7). Matrix Operations's advantage is ratings volume (19 vs 2). On price, update cadence, device support and iOS requirement there is nothing between them.
