Bigsam Cargo is a shipping companion app built for anyone sending parcels, boxes, barrels, appliances, or pallets by air or sea. Instead of guessing at rates or waiting on a reply, the app puts a full set of planning tools directly on your phone, ready to use even without a signal.

At the center of the app is a cost and time calculator. Choose air or sea freight, pick a direction and destination zone, enter a weight or a set of dimensions, and the app instantly works out a chargeable weight, an estimated cost, and a realistic delivery window. Every figure is shown in a single, consistent currency, and any estimate can be shared straight from the results screen through a text message, email, or messaging app of your choice.

Alongside the calculator sits a detailed service directory. Each shipping method, from door to door delivery and customs clearance to same day and business logistics, has its own page explaining how it works, what it is best suited for, and a full breakdown of current rates. A searchable frequently asked questions section answers the most common shipping questions without needing to look anything up elsewhere.

Planning a visit to drop off or discuss a shipment is handled through a built in booking screen. A calendar view shows the coming weeks, working hours are calculated automatically for each day, and available time slots are displayed alongside slots that are already busy, so it is easy to pick a realistic time. A confirmed booking can be added to your phone's calendar with one tap, and cancelled just as easily if your plans change, all without typing in any personal contact details.

For preparing a shipment, the app includes a product catalogue covering standard box sizes, barrels, household appliances, electronics, and vehicles, each with an at a glance price and description. A templates and specifications section provides ready to fill packing lists, commercial invoice layouts, customs declaration checklists, and a dimensions and weight worksheet, with text that can be copied to the clipboard or shared instantly. A knowledge base rounds things out with packing tips, customs basics, and a glossary of shipping terms such as full container load, air waybill, and volumetric weight, so unfamiliar language never gets in the way.

A daily schedule tool shows which dispatch runs are happening today, which office hours currently apply, and what is coming up over the next week, making it simple to time a booking or a shipment around the right cutoff.

The interface runs in a clean, distraction free full screen layout with no system bars competing for space, uses a warm, consistent color palette throughout every screen, and keeps every saved booking stored privately on your own device rather than on a remote server. No account, sign in, or ongoing internet connection is required to plan a shipment, check a price, or read a guide.
