Verdict

The call

The clearest difference is monetization model: Linear Algebra Visualizer at freemium against Frontend Masters's subscription. Linear Algebra Visualizer also leads on rating (5.0 vs 4.7). Frontend Masters's advantage is ratings volume (340 vs 1) and iOS requirement (11.0 vs 18.6). On price, update cadence, ads and in-app purchases there is nothing between them.
