Chemistry Experiment Simulator vs Jia Cube

「化学实验模拟」 is an online chemistry simulation learning tool. Built with digital simulation technology, it creates hazard‑free virtual lab scenarios. It supports independent chemistry practice and in‑class supplementary learning, letting users perform various chemical‑reaction operations without leaving home. Main Features: Interactive Virtual Workbench This feature includes a central simulated beaker and draggable reagent shelf. Particle effects visualize gas generation, solution convection and other reaction processes. Users can directly observe color changes, precipitates, bubble formation and other phenomena, recreating the hands‑on experience of real‑world lab experiments. Thermodynamic Adjustment Built‑in heat source and temperature‑monitoring system. Heating and cooling alter liquid states. Users can explore how temperature affects chemical reactions and liquid phase changes, gaining intuitive understanding of thermally‑driven chemical principles. Smart Experiment Analysis & Guidance The system automatically identifies ions and substance states inside the beaker. It delivers real‑time operation tips and substance descriptions, helping users interpret chemical equations and plan next experimental steps to reinforce foundational chemistry knowledge. Secure Account Management Built‑in access to legal agreements and local‑data storage. Users may log out, delete their account, and submit feedback to support. You control your personal data and can review privacy‑related policies at any time to safeguard your information. No physical lab equipment or safety risks are required. It balances hands‑on simulation and knowledge learning. Download and enjoy engaging chemistry simulation. VIP Auto‑Renew Subscription Terms Subscription period: 1‑week auto‑renewable VIP membership.

Let your hands find order. Jia Cube brings interactive 3D puzzles, illustrated lessons and personal timed challenges together. Take time to understand a move, follow an arrow or start a fresh scramble and challenge your previous result. Turn a sequence of letters into something you can see and try. SEVEN PUZZLES TO EXPLORE Discover 2x2, 3x3, 4x4 and 5x5 cubes, plus 2-, 3- and 4-layer pyramid puzzles. The 2-layer pyramid uses independently turning tips. Explore different structures and build familiarity with corners, edges, centers and layers. LEARN THROUGH PICTURES Compare a starting position with a target diagram, then work through the steps. Lessons introduce beginner layer-by-layer ideas for the 3x3 and concepts such as centers, edge pairing and reduction for larger cubes. Visual examples help you connect a move with its purpose instead of only memorizing notation. KNOW WHAT TO TURN NEXT On-puzzle arrows and next-move prompts show the intended movement. For cubes, U, D, L, R, F and B are explained as up, down, left, right, front and back, alongside turn direction. Guidance for the current scramble retraces its recorded moves in reverse. Illustrated lessons use example positions; this is not a camera scanner or an automatic layer-by-layer solver for any external puzzle. CHOOSE YOUR PACE Learn: combine diagrams, instructions and animated turns. Train: get ready, follow the 3-2-1 countdown and begin a personal timed attempt. A completed solve records time and moves; ending a started attempt early marks it unfinished. Free play: explore turns, change the view and scramble again without a running challenge timer. BUILT FOR TOUCH Swipe tiles to turn a layer, drag empty space to orbit the puzzle and pinch to zoom. Cubes also offer six face buttons and reverse-turn controls. Practice on iPhone or enjoy a roomier view on iPad. KEEP A HISTORY OF YOUR PRACTICE Review dates, times, move counts and scramble sequences. Filter results by puzzle and revisit completed and unfinished attempts. Use your history to set a clear goal for your next practice session. A SOUNDTRACK YOU CONTROL Optional ticking gives timed practice a steady rhythm. Ambient music starts switched off and can be enabled when you want it. Adjust both in your profile. CONTINUE IN YOUR LANGUAGE Choose Simplified Chinese, Traditional Chinese, English, Japanese, Korean, Polish, German, Portuguese or Spanish, or follow the system language. Sign in with Apple. Results are saved locally and can sync through iCloud when available, using the same relevant accounts on your devices. FREE FEATURES AND PRO All modes for both 2-layer puzzles are free. Lessons and free play are free for every puzzle. Training with cubes and pyramids of 3 or more layers requires an active Pro subscription or lifetime purchase. Monthly, annual and one-time lifetime options unlock the same training range. Subscriptions renew automatically and can be managed or canceled in your App Store account settings. Access continues until the paid period ends. Lifetime access is a one-time purchase and does not cancel an existing subscription. Restore purchases is supported. See the purchase screen for local pricing. Observe. Understand. Practice. One move at a time.
