# Neutrons4Science vs Physics Lab AR

The clearest difference is review sentiment: Neutrons4Science at 100% against Physics Lab AR's 48%. Neutrons4Science also leads on in-app purchases (none vs 7) and iOS requirement (8.0 vs 15.0). Physics Lab AR's advantage is rating (4.7 vs 4.0) and ratings volume (1.8K vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Physics Lab AR sells 7 in-app purchases, starting at $1.49 per month. Neutrons4Science asks for nothing beyond the download.

Physics Lab AR holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Physics Lab AR has 1.8K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Neutrons4Science's written reviews are positive against 48% of Physics Lab AR's, so the app with the better star average is not the one people write more warmly about.

Neutrons4Science ships an update every 8 months, Physics Lab AR every 2 months. The most recent releases landed on September 23, 2026 and October 14, 2026 respectively.
