Enter the world of neutrons! They are a powerful and highly acclaimed tool not only for the study of condensed matter (the world we live in) but also for confirming our current understanding of physics. What's more, you don't even need to be a scientist to use Neutrons4Science. Just be curious! Neutrons and protons are elementary particles constituting the nucleus of atoms. The neutron has no electric charge but has a spin and a magnetic moment. Neutron beams - like beams of X-rays, electrons or muons - are valuable tools for studying the multitude of materials that surround us in our daily lives (alloys, magnets, superconductors, polymers, colloids, proteins, biological systems, …). However, the way neutrons interact with matter is quite unique and, as a result, it can often reveal to us what is normally hidden. With Neutrons4Science you can discover one of the many types of neutron spectroscopy. The neutron also answers questions on the very foundations of physics, helping us to solve some of the great mysteries of the universe (Is the Grand Unified theory valid? Is there a fifth fundamental force? ...) As an example, Neutrons4Science gives you insights to a brand new method of neutron spectroscopy that takes advantage of the quantum states of this light neutral particle. Neutrons4Science lets you experience neutron science through three interactive 3D animations: • ThALES: Use a neutron spectrometer as if you were performing a real experiment. • Magnons: Discover the spin waves that exist inside magnetic materials and understand how ThALES can observe them. • GRANIT: Discover an innovative gravitational spectrometer based on neutron quantum states in a gravitational field. These three educational animations were developed with the help of scientists at the "Institut Laue-Langevin", one of the world's flagship facilities for neutron science.

Provided by the Nuclear Data Section of the International Atomic Energy Agency, the app gives properties of more than 4 000 nuclides and isomers. A Chart of Nuclides, with zooming and tapping enabled, and a Periodic Table of Elements are included to allow easy selection and navigation. Filter criteria on half-life, decay mode, radiation type and energy can be selected. Summary data are presented in a scrolling list, with a details page for each nuclide containing web links to the data sources and further information such as level and decay schema. The filtered nuclides can be visualised on the Chart of Nuclides. Data are taken from the most recent and reliable sources, and optimal search-and-retrieve performance is achieved with an embedded database, meaning that no network connection is required.

Verdict
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.
