# Neutrons4Science vs Isotope Browser

The clearest difference is rating: Isotope Browser at 4.8 against Neutrons4Science's 4.0. Isotope Browser also leads on update cadence (every 6 weeks vs every 8 months) and ratings volume (27 vs 1). Neutrons4Science's advantage is review sentiment (100% vs 83%) and iOS requirement (8.0 vs 11.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Isotope Browser holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Isotope Browser has 27 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 83% of Isotope Browser'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, Isotope Browser every 6 weeks. The most recent releases landed on October 9, 2026 and October 16, 2026 respectively.
