Verdict

The call

The clearest difference is in-app purchases: Physics Toolkit at none against Photronium's 1. Physics Toolkit also leads on ratings volume (52 vs 10) and iOS requirement (11.2 vs 16.4). Photronium's advantage is rating (5.0 vs 4.6). On price, review sentiment, ads and device support there is nothing between them.
