Chemancy
Read full descriptionHide full description
Deep in the rock, under fog and runes, lies the order of the elements. It is waiting for someone to wake it. Chemancy turns chemistry into an adventure. Four games, one rock, not a single worksheet. You set elements until the periodic table grows out of the cave wall. You push atoms together until they become water, ammonia, sulfuric acid. You bring a balance to rest with an equation lying on it. And in the lab you mix whatever you like, just to see what happens. You learned it anyway. That is the trick. WAKE THE PERIODIC TABLE Every element to its place, one after another. What you set is struck into the rock and stays there. Play a perfect round and the rock breaks open โ behind it lies a cave only the best will ever see. BUILD MOLECULES Push the atoms until they find each other. 168 compounds are waiting to be discovered, and each one tells you what it is, where it occurs and why the world needs it. MASTER THE REACTIONS An equation rests on a glowing balance beam, and the beam tips towards the heavier side. Find the right numbers and it hangs level โ then it burns through. 112 equations, from the hydrogen pop test to titration. ENTER THE LAB No task, no rules, no end. Pull atoms out of the periodic table into the pit, add a spark, some heat or light, and watch what forms. Then let water in โ from there it is a different chemistry. Acids break into their ions, alkali metals react with it, salts dissolve. Boil the water away and they crystallise again. 178 reactions are waiting to be found, and not one of them is set as a task anywhere. When you get stuck, the shelf shows the way: for every substance it tells you how it really forms in your lab โ not the textbook synthesis, but the one that works here. PROOF OF YOUR MASTERY Place all 118 elements correctly and the system wakes one last time: lightning strikes, light runs along every path until the whole rock glows. Then you receive a certificate โ an image to share, carrying a code that proves it is real. Anyone who shows it has earned it. And the colour stays: teal, violet or gold, depending on the difficulty, kept in the fog around the menu stone. KNOWLEDGE THAT HOLDS Behind the game sits a learning area that fears no exam. For all 118 elements the values that actually get asked, plus twelve colour views of the whole table. And profiles for all 168 compounds, open from the start. Exam, degree or pure curiosity โ it sticks here, because it was fun. FAIR AND TIDY โข Completely offline โข No data collection, no tracking, no accounts โข Free, with no ads โข 14 languages, on iPhone, iPad and Mac The rock is waiting. Start with one element.

Master the entire periodic table with AtomicRecall โ the chemistry learning app that uses proven mnemonic techniques to help you remember all 118 elements effortlessly. WHY ATOMIC RECALL WORKS Traditional memorization fails because it treats elements as abstract data. AtomicRecall transforms each element into a memorable story using three powerful memory anchors: - Visual Anchor: A vivid mental image connected to the element name - Symbol Anchor: Letters transformed into memorable pictures - Story Anchor: A short narrative combining both anchors For example: Hydrogen (H) becomes "A house-shaped hydrant spraying water" โ linking the symbol H (House) with Hydro (water) in one unforgettable image. FEATURES Learn Mode Browse through all elements with detailed flashcards. Each card reveals the element symbol, name, category, and all three mnemonic anchors. Shuffle cards, mark favorites, and track which elements you have seen. Practice Mode Four different practice styles to strengthen your recall: - Number to Element: See the atomic number, recall the element - Symbol to Name: See the symbol, recall the full name - Name to Symbol: See the name, recall the symbol - Mnemonic to Element: See the story, recall the element Quiz Mode Test your knowledge with multiple-choice questions. Get instant feedback and learn from mistakes with mnemonic hints after each answer. Progress Tracking Monitor your learning journey with detailed statistics. Track elements seen, mastery level, quiz accuracy, and daily streaks. Organized Learning Study elements in groups of 10 (1-10, 11-20, and so on) for focused, systematic learning. FREE TO START Elements 1-20 (Hydrogen to Calcium) are completely free. Unlock all 118 elements with a one-time purchase โ no subscriptions, lifetime access. PERFECT FOR - Chemistry students preparing for exams - Medical and pharmacy students - Science enthusiasts - Anyone who wants to finally master the periodic table Start learning smarter today. Download AtomicRecall and transform how you remember chemistry.
