ARMET (Augmented Reality METabolic pathways) uses the camera to show, in augmented reality, the molecules of metabolic pathways on printed cards. Point your device at the cards: each one shows the 3D model of its molecule, and you build the pathway by answering questions. • Study Mode: step-by-step questions through glycolysis, the Krebs cycle and steroid hormone synthesis (aldosterone, cortisol, estradiol, estrone and testosterone). Tap the right molecule to move on. • Game Mode: random questions with several answers and a timer; you get a score at the end. • 53 molecules in 3D (ball and stick), from sugar phosphates to cholesterol. • The printed board works as an augmented reality menu; on-screen buttons work too. • No cards or no camera? Choose the molecules from a list with 3D thumbnails. • Classes: teachers create a class and follow their students' answers; students join with the class code. You can also use it without signing up (anonymous mode). • Portuguese, English and Spanish. The board and the cards can be printed from the Documents menu, together with a worksheet for each pathway. Developed at the Educational Technology Laboratory (LTE), Institute of Biology, University of Campinas (Unicamp), Brazil. Concept: Juan Carlos Vega Garzón, Márcio Luiz Magrini, Brian Cohen and Eduardo Galembeck. New version (2026) rewritten in HTML5, with its own reader for the original card markers — the 2014–2016 cards and board still work.

Make complex biology click, and make it stick. Short, illustrated lessons explain one idea at a time, a quick quiz shows you what you've understood, and flashcards bring back what you'd otherwise forget. Module 1 is free, with no account and no subscription. Understand it, one step at a time Each section breaks complex ideas into clear explanations and diagrams, so you can follow even the hard topics. A quiz before you move on shows you where you stand. Lessons, quizzes, flashcards and the glossary all work offline, so you can study anywhere. Stuck? Ask Ribo, your AI study helper You don't have to search the web or wait for the next class. Ribo answers questions about the lesson page, glossary entry or missed quiz question in front of you. A few questions are free every day, and purchased modules give you more. Answers can be wrong, so check them against the lesson. Turn your lecture slides into flashcards Exam coming up? Photograph your slides or import the lecture PDF, and the glossary terms in them become flashcards. Swipe through the pages, zoom in and tap a term to read its entry. It all happens on your device, so your slides stay with you. Keep what you've learned Turn any topic into a flashcard deck: spaced practice brings back what you'd otherwise forget and focuses on the cards you find hardest. The Review tab shows you what to do today: the cards that are due, the quiz questions worth another look, your streak and your progress. Forgot a term? The glossary has the key terms from every module, plus the 20 amino acids and the nucleobases. What you'll learn Module 1: Chemistry of Life – atoms & elements, bonds, water, pH, biomolecules Module 2: Genetics – chromosomes, replication, transcription, translation, regulation Module 3: Evolution – history of life, phylogeny, selection, drift, speciation, molecular evolution Module 4: History of Science – ideas, methods, and experiments that shaped modern biology Module 5: Cell Biology – membranes & transport, organelles & energy, cytoskeleton, signaling, cell division Module 6: Development – fertilization & body plans, differentiation, pattern formation & morphogenesis, growth & repair, evo-devo Additional topics are planned for future updates, including Animal Physiology, Microbiology & Immunology, Plant Biology, and more.
