A visual periodic table app covering all 118 elements. 2D PERIODIC TABLE A grid layout by group and period. Categories like alkali metals, halogens and transition metals are color-coded, so you can see an element's classification at a glance. Pinch to zoom into crowded blocks of elements for a closer look. ELEMENT DETAILS Tap an element to see its electron configuration through an intuitive rotating shell animation. Dig deeper with atomic number, mass, melting and boiling points, density, electronegativity, year of discovery, real-world photos with usage examples (sourced and licensed), a list of isotopes, molecular structures of representative compounds (water, carbon dioxide, ozone and more), and electron configuration changes for common ions. WHO IT IS FOR - Students studying basic or advanced chemistry - Anyone curious about elements and chemistry - Looking for reference material for a school project or class FEATURES - All 118 elements and 96 real photos bundled from the start — every feature works offline - Japanese and English supported (switches automatically with your device language) - No ads, no account required, no additional purchases - All photos are public domain or Creative Commons, with sources credited

Verdict
The clearest difference is in-app purchases: Elements Gallery at none against Atomo's 1. Atomo's advantage is iOS requirement (13.0 vs 26.0). On price, update cadence, ads and device support there is nothing between them.
