Offload

Every day, millions of people fly with empty space in their luggage allowance — while someone, somewhere, is paying a fortune to move a small item along the exact same route. Offload came to us with a simple idea to close that gap: a marketplace that connects senders who need something carried with travellers already making the trip.

The brief was to design and build a two-sided mobile app from scratch. A sender posts what they need moved and where; a traveller heading that way offers to carry it in their spare allowance and earns a fee for the space. We were asked to shape the whole experience in Figma and ship it as a single cross-platform Flutter app for iOS and Android.

A peer-to-peer marketplace only works if both sides feel safe. Senders are handing an item to a stranger; travellers are agreeing to carry something on their behalf. The product had to make each side feel in control at every step — from posting a request, to agreeing terms, to handover — without drowning either in friction.

On top of the trust problem sat a structural one: the same app had to serve two very different mindsets. A traveller thinks in routes and dates; a sender thinks in items, destinations, and price. We had to design a single, coherent app that let a person be both — request something today, carry something tomorrow — without ever feeling like two apps bolted together.

One identity, two roles — every user can send and carry. The app remembers context and surfaces the right flow rather than forcing people to pick a lane on sign-up.

Requests meet trips — senders post what they need moved and where; travellers publish their routes and dates. The matching logic brings the two together so a request finds the travellers who can actually fulfil it.

Trust as a feature — clear profiles, transparent service fees, and a structured request-to-handover flow make the exchange feel accountable from first tap to delivery.

We designed Offload end to end in Figma — a complete component system covering onboarding, the sender and traveller flows, request creation, matching, offers, and the in-app agreement. Working in a shared design system meant the two roles felt like one product, with consistent patterns for cards, statuses, and actions across every screen.

The build is a single Flutter codebase in Dart, shipping to both iOS and Android from one source of truth. Flutter let us move the polished Figma motion and micro-interactions straight into production and keep the two platforms perfectly in sync — one team, one codebase, two native-feeling apps.

Core flows — posting a delivery request, browsing trips, sending and accepting offers, and tracking a request through to handover — were built as reusable, state-driven screens so the experience stays fast and predictable as the marketplace grows.

Offload is built entirely in Flutter with Dart, giving both iOS and Android a single, maintainable codebase. That means every new feature — a change to the request flow, a new profile field, an update to the matching screen — ships to both platforms at once, at a fraction of the cost of two native builds.

The interface leans on Flutter's rendering engine to keep the marketplace feeling smooth: instant transitions between roles, responsive lists of requests and trips, and a design that stays pixel-faithful to the Figma file on every device size.

Offload launched as a polished, cross-platform app that lets anyone switch effortlessly between sending an item and earning from a trip they were already taking. The design makes a genuinely novel idea feel obvious, and the Flutter build means the founders can iterate on both platforms from a single team.

What started as a clever observation — that empty baggage is wasted capacity — is now a working product with a clear, trustworthy flow from request to handover, ready to grow its network of senders and travellers.
