Know exactly how your cargo fits — before you load it.
Enter your carton sizes and quantities, pick a container, and get a real 3D loading plan in seconds. Works entirely offline, keeps your data on your device, and costs one single payment.
Why it is different
Most load planners are either a spreadsheet you have to trust, or a cloud service that wants your data and a monthly fee. This is neither.
Offline and confidential
No internet connection, no sign-up, no ads, no analytics, no tracking. Your dimensions, cargo names and shipping details never leave your device — which matters when confidentiality is contractual.
An engineering-grade engine
Every carton is supported by a solid surface or the container floor, so nothing floats. Two independent strategies are evaluated and the better one is kept, giving a higher fill rate and a stack your team can actually build.
Buy once, use forever
One purchase unlocks every feature: no subscription, no recurring charge, no in-app purchases, no "pro" tier. Future updates are included, and nothing is ever held back behind a paywall.
Everything the planner does
Built around the real constraints of loading a container, not around a demo.
- Interactive 3D view — orbit, pan and zoom; tap any carton to read its details.
- Support-constrained packing — items never float in mid-air.
- Multi-container loading — fills container after container until everything is placed.
- 8 standard containers — 20GP through 45HQ, open-top and reefer included.
- Custom container — your own internal dimensions and door opening.
- Pallet mode — unitize cargo for forklift handling.
- 8 pallet presets — plus custom pallets with self-weight and max load.
- Automatic stacking height — derived from container height and pallet rating.
- Payload validation — maximum weight enforced as you type.
- Fragile rules — nothing is ever placed on top of a fragile item.
- Rotation control — lock items upright when the product demands it.
- Door-opening limits — every piece is checked against the real door frame.
- Load order pick list — step-by-step sequence matching the 3D plan.
- Live statistics — fill rate, CBM used, total weight, piece and container count.
- PDF and image export — a print-ready A4 landscape sheet, or a high-resolution picture.
- Local plan history — save, reload and reuse previous calculations.
- Light and dark themes — or simply follow your system setting.
- 15 languages — from English and 简体中文 to العربية and हिन्दी.
