Smart Packer: 3D Cargo Planner

Smart Packer is a professional-grade 3D loading calculator designed for logistics dispatchers, freight forwarders, and exporters. Powered by an industrial-grade Rust physics engine, it optimizes every inch of space, eliminating the risk of left-behind cargo due to estimation errors. Enjoy a pure, fast, and secure tool: 100% offline, zero ads, and strictly no user data collection. Lifetime Buyout: New users enjoy 5 free calculation trials to thoroughly evaluate the algorithm (PDF export requires Pro). With the smart quota system, repeating previous calculations or merely changing item names won't consume your trials. You also receive 20 free AR data inputs (infinite use for scanning only). Once satisfied, a single one-time payment unlocks the Pro version forever, granting unlimited access to all professional features. Core Features: 1. Industrial-Grade Algorithm - Core Loading Foundation: Built on strict rules including "heavy-on-bottom", precise bottom support area validation, block loading strategies, and spatial height constraints (side & front) to ensure real-world stability. - Cylinder Optimization: Exclusive honeycomb nesting algorithm for cylindrical items (drums/rolls) to maximize corner space. - Backtracking & Compaction: Performs final physical compaction simulation after core loading to eliminate minor gaps. - Deformation Tolerance: Accounts for cardboard box bulging during transit, preventing unexecutable tight fits. 2. AR Camera Scanner - Point your camera at any box to automatically detect its length, width, and height. Enjoy 20 free data inputs and infinite free use if only scanning to measure. 3. Smart Fleet Dispatch & Cost Optimization - Blind Recommendation: Unsure which vehicle to use? The system automatically calculates and recommends the most cost-effective combination without manual assignment. - Global Optimization: Weighs "lowest freight cost + highest fill rate + safest CoG" for vehicle allocation, avoiding greedy algorithm limitations. - Vehicle Synergy: Prioritizes your custom fleet and automatically matches market vehicles when capacity is insufficient. 4. Complex Business Rule Support - Multi-Stop LIFO: Fully supports multi-destination routing by strictly adhering to Last-In-First-Out unloading sequences. - Detailed Constraints: Supports rules like "Upright Only", "No Top Load", and "Stacking Limits". - Safety Compliance: Real-time calculation of Center of Gravity (CoG) and axle weight distribution to avoid overload fines. - Step-Deck Trailers: Accurately configure gooseneck dimensions for custom flatbed trailers, simulating true physical space. 5. Immersive 3D Visualization - Playback Control: Use the progress bar and play button to freely control, pause, and replay the exact loading sequence. - 360° Interaction: Freely rotate and zoom to inspect loading details and internal structures. - X-Ray Mode: Tap any item to highlight it while fading the rest for precise locating. 6. Professional Report Export - PDF Export: Generate comprehensive reports featuring 3D views, statistics, and step-by-step manifests in one tap. - Data Insights: Detailed analysis of volume utilization and weight distribution. - Offline Plan: Export a .smartpacker file so recipients can open the 3D loading plan in SmartPacker on iPhone, iPad, or a supported Android version. iOS can also open offline plans shared from Android. 7. Diverse Data Import Methods - Supports manual entry, AR camera dimension scanning, clipboard table pasting, CSV file import, and the new document table scanning.
