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.

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 call

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.
