EXPLORE 118 ELEMENTS A visual periodic table with properties, electron shells, history and uses. Search by name, symbol or atomic number, and zoom to explore. LEARN AND CALCULATE 182 reference topics, from basic concepts to organic chemistry. 14 solvers show their steps for balancing reactions, redox, oxidation states, molar mass, amounts of substance, solutions, pH and more. Consult solubility and other reference tables. Practise across 15 topics with feedback and explanations. PERIODIC TABLE PRO • Virtual lab: combine atoms and explore nearly 600 substances with animated molecules, properties, uses and safety information. • On-device AI tutor: ask in your own words. Equations and molar masses are checked with the app's calculation engine. • Scanner: photograph a reaction equation and balance it. • Unlimited practice sessions. The periodic table, element cards, handbook and solvers remain free. 20 LANGUAGES The app uses a supported device language on first launch. You can change it in the app; your choice is saved. Formulas retain their standard direction. Light and dark themes. PRIVACY AND AI REQUIREMENTS No accounts, ads, tracking or analytics. Reference content is available offline after installation. The AI tutor requires a compatible iPhone or iPad with iOS/iPadOS 26 or later, enabled Apple Intelligence and a downloaded model. AI language and region availability depend on the device and system version. Questions are processed on the device. Pro is available as a monthly or yearly subscription with a one-week free trial for eligible new subscribers, or a one-time purchase for lifetime access.

Verdict
The clearest difference is ads: Periodic Table at none against Atomo's shown. Periodic Table also leads on update cadence (every 3 days vs monthly). Atomo's advantage is iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.
