Numas Study vs Chemical Equations Trainer

Numas Study is the smart study app for university students and anyone preparing for an exam, a public competition, or a certification. Upload your materials, import your question bank, and organize your revision effectively. The core features are ready to use, with no setup required. WHAT YOU CAN DO: READING AND MATERIAL MANAGEMENT Upload your PDFs and read them whenever you want. Listen to your materials as audio while you're on the go, with built-in text-to-speech. HEADPHONE REVIEW Review a handout hands-free, even with the screen locked: the voice reads it step by step and asks you the review questions, with a pause to think and then the answer. Use your headphone buttons to say whether you knew it, and your answers count in your reviews. QUIZZES FROM YOUR QUESTION BANK Import your question bank and start practicing right away. Answer checking works directly on your device, with nothing external required. FOCUSED REVIEW The app analyzes your quizzes and materials and shows you which topics to focus on, ranked by priority. Tap a topic to jump straight to the material that explains it. STUDY PLAN Enter your exam date and organize your study day by day, balancing reading, quizzes, and review. Choose the handout order (balanced, course order or most asked in the question bank) and reorder readings by hand: days and minutes are worked out again automatically. MAP OF THE DAY With Pro, for each day of your plan, a diagram of the ideas in that day's handouts and how they connect. Each block carries the sentence from your handout it comes from, with the page; anything suggested by the AI is marked as such. Hide the blocks and test yourself: the ones you didn't know become review questions. MOLECULAR STRUCTURES For scientific materials, the app recognizes molecules and displays them in 2D. SCIENCE TOOLS Interactive periodic table with 118 elements and chemistry calculators: concentrations and dilutions, pH of acids and bases, buffer solutions. Open them right where you study — while reading a document, taking a quiz or working in the lab — with contextual help in every tool. All calculations run on-device, no connection needed. ICLOUD SYNC Your materials and progress sync automatically across iPhone, iPad, and Mac. OPTIONAL AI FEATURES Numas Study can add advanced artificial intelligence features — such as generating summaries, quizzes from your own materials, and oral exam simulations — by connecting your personal key from a supported AI provider. These features are entirely optional: the app is fully usable without them. PLANS: Free: 1 course, 5 materials, 5 elaborations per day Pro: everything unlimited Start studying more effectively today with Numas Study.
