What's New in Periodic Table and Chemistry
2.0.1
October 3, 2026
Periodic Table is back on the App Store. I first published it in 2019 as a personal project, and for years it couldn't be downloaded. Version 2.0 is rebuilt from scratch for the people studying chemistry today: • Data checked against PubChem, IUPAC, NIST and the IAEA, with the sources in plain sight. What isn't known shows as unknown. • A new data sheet for every element: orbital diagram, isotopes, oxidation states, NFPA 704 diamond, photo and emission spectrum. • Search by name, symbol, atomic number, CAS number or family. • Eleven calculators with history: molar mass, empirical formula, inorganic and organic nomenclature, equation balancing (redox too), solutions, gases, colligative properties, chemical equilibrium, pH, electrochemical cells and analytical statistics. • 147 reactions with their ΔH°, ΔS°, ΔG° and K, 22 lab tables and a 173-term glossary. • Quizzes generated from the app's own data. • Sortable lists, trends, a heat map, element comparison and, with Pro, PDF export. • Apple Watch app, widgets, Siri, Shortcuts and Spotlight. • iPad and Mac, 20 languages, Dark Mode, VoiceOver, larger text, shapes that tell families apart without color, and thirteen themes named after scientists (three free, one of them color-blind friendly). Everything that was free is still free. Pro is a one-time purchase for life or, if you prefer, a monthly or yearly subscription. If you bought Premium in the previous version, it's still yours: it comes back when you open the app, or from More › Restore purchases. Spotted a value that looks wrong?
