## What is Smart Packer?

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.

### 5/5 — 纸箱摆放朝向不明显

*2026-08-24*

有些纸箱长宽相差10cm，在3D里辨认不出来摆放朝向，希望能在3D里能直观的看到纸箱朝向或者箭头提示

**Developer response:** 感谢您的支持和细致反馈！您之前提到的纸箱朝向不易辨认问题，已经在最新版本中进行了优化。

现在 3D 视图中新增了货品三轴朝向提示，可以更直观地判断纸箱的实际摆放姿态；同时也支持查看单件货品的长、宽、高尺寸，以及整体已装货物的外包尺寸，并会根据当前单位设置进行显示。

欢迎更新到最新版本体验。如果后续在实际装载过程中还有不方便的地方，也非常欢迎继续反馈，我们会持续优化。

### 1/5 — 计算不行，

*2026-08-19*

测试了4个类似的，只有这个付费的，直接说装不进。67方

**Developer response:** 很抱歉这次结果没有达到您的预期。装载是否可行不能只看总体积（67方），还取决于单件货物尺寸、总重量及车辆载重。智装箱会同时考虑重不压轻、支撑面积、避免货物孤立堆高、货物重心与车辆重心、堆叠层数、卸货次序、货物旋转情况等实际装载约束。正常情况下，只有货物总重量超过车队载重，或某件货物任一摆放方向都无法放入现有货厢时，才会提示“装不进”；其他情况系统都会自动寻找可行车辆并生成方案。如果您的数据不属于以上情况，请通过 hi@black-dim.com 联系我们并提供货物清单和车辆参数，我们会立即核查是否存在异常并协助生成方案。

### 5/5 — 目前MAC端最好的装柜软件

*2026-08-11*

外贸从业人员福音，一定推荐使用！客服反馈也很快，期待越做越好 Jurrivh

### 1/5 — 软件一直在计算中

*2026-07-21*

什么情况啊  刚购买的软件   计算不出来  发邮件也没回

**Developer response:** 您好，您的邮件在发出后1个小时已经给您回复，请关注一下您的邮箱，如果软件一直在计算中，可能是由于您添加了太多货品，软件在进行装箱计算时，会进行大量的逻辑验证，货品数量越多耗时越长，您可以先适当减少货品进行测试。

### 1/5 — 配载方案落后

*2026-06-03*

人工计算可以装下的，软件计算的装不下

**Developer response:** 您好，抱歉给您带来不好的体验。装载结果会受到货物尺寸、数量、重量、是否允许旋转、装载顺序、车辆内尺寸等条件影响。不知道您在计算时是否考虑到了每层的承重以及每件货顶部的支撑面，或者前 20% 重量货物尽量在车辆两侧均匀放置，这些现实因素都可能影响装载结果。若方便的话，欢迎通过邮件 hi@black-dim.com 联系我们，并提供货物和车辆参数，我们会帮您核查具体原因并持续优化算法。感谢反馈。

### 5/5 — 软件问题咨询

*2026-05-29*

我想请问下物理属性里数量最大只能1999吗？不能设置成3000以上的数量吗

**Developer response:** 您好，感谢您的五星评价！目前单个规格数量上限为 1999 件，主要是因为智装箱采用离线本地计算，不上传数据、不依赖服务器，为了保证不同机型上的计算稳定性，暂时做了保护限制。如果某个规格货物超过 1999 件，您可以新建两个相同规格的货物，只要名称不同即可，例如“货物1”和“货物2”，使他们相加的数量等于总数量。后续我们会评估支持更多数量，感谢您的反馈！

### 5/5 — 1

*2026-05-19*

软件不错，有联系方式吗，沟通一下

**Developer response:** 您好，感谢认可。您可以通过邮箱联系我们：hi@black-dim.com，也可以在 App 中点击 “设置-联系我们-发送邮件”，我们会尽快和您沟通。

### 5/5 — 方案合理速度快，建议加个扫码

*2026-04-24*

计算速度快，界面设计美观优雅，这点很好，强烈建议开发对出库单拍照识别的功能，有时候派货单子杂，照一张相就全部进去，能省太多时间

**Developer response:** 感谢您的认可。OCR单据扫描录入功能已经在我们的近期开发规划中，并一如既往地采用纯本地化的高效处理，帮您节省更多时间。感谢您的宝贵建议，敬请期待后续更新。

### 2/5 — Only for large cargo trucks

*2026-04-20*

I need to be able to use this as a delivery driver in my SUV, but you don’t have a way to put in those smaller dimensions. As well as width. I only see length and height. Adding a way to take a picture of a list of items and their dimensions (3 boxes - 69”x34”x30”) and then asking the app, will these items fit my cargo area. That’s what I really need.

**Developer response:** Hello! Thank you for the feedback. You can absolutely use this app to plan your SUV cargo space.

1. Vehicle dimensions: Simply convert your cargo area measurements from inches to feet (e.g., an 84" depth is entered as 7 ft).

2. Finding the width: In the "Add Custom Truck" window, the "Internal Width" field is located directly between "Internal Length" and "Internal Height". Also, please ensure the "Enable Step Deck" switch at the bottom is turned OFF, as it is a specialized feature for semi-trailers only.

3. Importing cargo: Our v1.4.1 update is now LIVE with a new "Batch" import tab! You can copy text from your paper manifest (using your phone camera's Live Text) and paste it into the app to instantly parse formats like "3 boxes - 69”x34”x30”". We are also actively researching a direct photo scanning feature to automatically extract cargo dimensions for a future update.
We hope this improves your experience. If so, we'd appreciate it if you could reconsider your rating! Contact us via hi@black-dim if you need further assistance.

### 5/5 — 您好开发者

*2026-04-07*

货物有的超过3m，甚至3m2，但是实际输入只能到2m6，这方面能改下上限吗？能否出个一键扫清单功能，就不用一个个手动输入了，能否给个联系方式，出点钱也是可以的。

**Developer response:** 您好，感谢您的持续关注与深度反馈。针对您提出的尺寸限制，我们在刚刚上线的 1.3.2 版本中已将自定义货车的宽度上限拓宽至 4.0m，高度上限增至 5.0m，以满足超大件货物的计算需求。该版本同步新增了您之前提到的“高低板”高级设置，您可以前往车型编辑页面进行尝试。关于一键扫清单功能，我们正在调研端侧识别与语义解析方案，可能需要较长时间，力求在保持离线运行的前提下提供更高效的录入方式。如果您有进一步的定制化业务需求或合作意向，欢迎通过邮件 hi@black-dim.com 与我们取得联系。
