Case study — OrbitWren product

A React Native app for tracking what you hold and splitting costs with friends, built for the Pakistani market, with its own API and operations console behind it.

The challenge

Where it started

Shared expenses are social before they are financial: the hard part is agreeing what was spent and who owes what, without it becoming an argument. The app also had to work on mid-range Android handsets with intermittent connectivity, where a spinner waiting on a network call is not an acceptable answer.

What it does

Expense tracking

Spending is captured against categories as it happens, with recent activity on the home screen rather than buried in a report.

Budgets

Per-category budgets with progress against each, so an overspend is visible before the month ends.

Shared costs

Costs split with friends and settled in-app, which is the social half of personal finance most trackers ignore.

Spending insights

The app surfaces patterns worth acting on, such as a category running ahead of its usual week.

Offline tolerance

Local persistence and explicit network-state handling, so the app stays usable on a weak connection.

Push notifications

Delivered through Firebase, for budget thresholds and settlement reminders.

Architecture

The approach

  1. 01

    Built the app in bare React Native rather than a managed wrapper, so native modules — camera, document access, push — are first-class instead of constrained by a runtime.

  2. 02

    Handled authentication and push notifications through Firebase, keeping session handling and delivery off our own infrastructure.

  3. 03

    Designed for intermittent connectivity with local persistence and explicit network-state handling, so the app stays usable when the connection drops.

  4. 04

    Built the interface around the currency and conventions of its actual market rather than localising a US-shaped product afterwards.

  5. 05

    Supported the app with its own API and an operations console for client records, configurable wallet presets and cohort analytics.

The outcome

Where it landed

Users track holdings and settle shared costs from one app that keeps working on a weak connection. The operations team manages onboarding defaults and reads cohort behaviour without an engineer running queries.

Capabilities used

More work

A short conversation with an engineer, not a sales qualification call. If we're the wrong people for it, we'll say so and point you somewhere better.
