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.

Atomizer AR turns your iPhone or iPad into a portable quantum chemistry lab. Visualize atomic and molecular orbitals in 3D, render electron density clouds, and step into immersive WebXR augmented reality where molecules sit on your desk at real-world scale. — WHAT YOU CAN DO — • Explore atomic orbitals computed from real hydrogenic wavefunctions: 1s, 2p, 3d, 4f and beyond, with adjustable shell glow and Bohmian trajectory animation. • View any molecule's molecular orbitals (HOMO, LUMO, intermediates) computed via PySCF on the cloud, then rendered as interactive isosurfaces. • See ball-and-stick models in WebXR augmented reality. Tap "View in AR", point at a flat surface, place the molecule on a table, then pinch to scale and drag to rotate. • Pair your phone with the desktop using Atomizer Remote: enter a 4-letter code, then tilt your phone to control the on-screen molecule with your gyroscope. Live preview streams back to your phone in real time. • Browse 40+ molecules — water, glucose, caffeine, benzene, ammonia, ethanol, methane, sulfuric acid and more — with energy diagrams, dipole arrows, lone pairs (VSEPR) and MO correlation diagrams. • Calculate molar mass live from any chemical formula, including parenthesised groups like Ca(OH)₂ and (NH₄)₂SO₄, with per-element breakdown. • Balance equations, run stoichiometry, sketch molecules in 2D, and explore reaction pathways. — SUBSCRIPTIONS — Free: 5 molecule renders per period. All calculator tools and full periodic table. Californium Pass — $2.99/month. 50 renders monthly, priority compute queue. Einsteinium Pass — $6.99/month. Unlimited renders, GLTF export for AR/3D printing, protein visualization, priority support. Auto-renews unless cancelled at least 24 hours before the period ends. Cancel anytime in Settings → Apple ID → Subscriptions. Subscriptions sync across iPhone, iPad, and electronvisual.org.

Verdict
The clearest difference is in-app purchases: Neutrons4Science at none against Atomizer AR's 4. Neutrons4Science also leads on iOS requirement (8.0 vs 15.2). Atomizer AR's advantage is update cadence (every 4 weeks vs every 8 months) and device support (6 vs 3). On price, rating, review sentiment and ads there is nothing between them.
