# Physics Toolkit vs Photronium

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.

Both are free to download. Photronium sells 1 one-off in-app purchase. Physics Toolkit asks for nothing beyond the download.

Photronium holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Physics Toolkit has 52 ratings behind it against 10, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
