Every element, beautifully made - and a study system that actually makes it stick. Periodic Table: Elements pairs all 118 elements with original illustrations, real numbers, sourced isotope data, emission spectra, and a spaced-repetition study system that schedules each card for the moment you're about to forget it. Includes FSRS flashcards, 109 balance-checked reactions, a guided equation balancer, 3D atom view, macro-to-subatomic dive, and widgets. THE TABLE All 118 elements, each with original cover art, a plain-language story, and sourced data you can trust. Every element page shows where its facts come from. Pinch from the poster view into a data-rich focus grid, explore periodic trends, and search isotopes like c-14, carbon 14, and u235. STUDY THAT STICKS Spaced-repetition decks and flashcards adapt to your recall. Curriculum packs support AP, IB, A-Level, GCSE, and MCAT review. Custom drills and Test Rescue help focus study before an exam. Readiness and mastery tracking stay on your device. TOOLS Use the molar-mass calculator for real formulas, hydrates, and brackets. Explore a 3D atom view, element-of-the-day widgets, and classroom-friendly table tools. PRIVATE BY DESIGN No accounts. No ads. No analytics. No tracking. No cloud. The app works fully offline because the table ships inside the app. Available in 50+ languages. One-time purchase includes all current features. No subscriptions, ads, tracking, accounts, or cloud.

The access period does not renew or charge automatically; there is no subscription. Reference and study features work offline after download; purchases, restores, and external links may require internet.
Kimiya

Kimiya is a real chemistry laboratory in your hand. Put any of the 118 elements and hundreds of compounds into a beaker, flask or test tube. Add water, heat, light or electricity. Then watch: bubbles rise, solutions change colour, precipitates settle, metals burn with their own flame colours, and the balanced equation appears with the energy released or absorbed. EVERY ELEMENT, IN 3D • The full periodic table with animated Bohr models • Atomic mass, electronegativity, density, melting and boiling points, electron configuration, oxidation states, discovery and uses • Flame-test colours for every metal that has one A LAB THAT UNDERSTANDS CHEMISTRY • More than 100 curated textbook reactions with the observations you would actually see • A rule engine for everything else: ionic synthesis, the activity series, solubility rules, neutralisation, combustion, thermal decomposition, electrolysis and dissolution • Exact equation balancing and reaction enthalpy from standard formation data • Temperature and pH readouts, safety notes, and a clear explanation when nothing happens LEARN • A searchable reaction library you can run with one tap • Quizzes on symbols, equations, reaction types, colours and energy • A molar-mass calculator and a bilingual glossary KIMIYA PRO (one-time purchase) • AR: place the bench on your table • Electrolysis cell, spectroscope, round-bottom flask, thermometer and pH meter • 3D ball-and-stick molecule viewer for every product • Stoichiometry: limiting reagent and theoretical yield • Lab notebook to save and replay experiments • Timed expert quiz Fully in English and Arabic with true right-to-left layout. No account, no ads, no data collection. Kimiya is an educational simulation. Never attempt these experiments outside a supervised laboratory.

Verdict
The clearest difference is update cadence: Kimiya at every 3 days against Periodic Table's every 11 days. Periodic Table's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Periodic Table sells 2 one-off in-app purchases and Kimiya sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Periodic Table ships an update every 11 days, Kimiya every 3 days. The most recent releases landed on October 1, 2026 and October 9, 2026 respectively.
