Mobile app architecture review

A mobile app that has to launch in a second country, pass an accessibility review or survive its first real traffic needs a different architecture from a demo. A mobile architect reviews how the app is structured, where business logic lives, how localisation and payments are handled, and what to fix before the next market.

Mobile architect for multi-market consumer apps

Best for: seed and Series A startups with a consumer app · scale-ups expanding an app into new countries · corporate teams that must make an app accessible · founders who need a second opinion on a mobile codebase.

From the network

Selected cases from these experts’ profiles.

Localisation architecture: new country = configuration, not a rebuild

The same retail app had to support several languages, currencies and regional regulations. Our expert designed an internationalisation layer where language, currency and per-market regulatory rules are configuration. Each new market was added without rebuilding the app.

Payments and loyalty app for a multi-country retail chain

A large retail chain needed one app for paying at the point of sale, collecting loyalty rewards and buying in store, across several European countries. One of our experts led iOS on that app for about four years, spending weeks on the core design (payment-flow abstraction, loyalty as an independent module) before product code. The app grew to several hundred thousand monthly users across thousands of locations.

Accessibility (WCAG) for a connected consumer-device app

A connected home-device brand needed its companion app to be usable by people with disabilities. One of our experts led maintenance and optimisation of the app with a focus on WCAG compliance, fixing screen-reader, contrast and interaction issues. The app became more inclusive without a rewrite.

Second opinion on an AI-built or vibe-coded mobile MVP

A founder has a React Native or Next.js + Firebase MVP built quickly with AI tools and wants to know if it can carry real users and payments. The expert checks where business and payment logic live, how failures are handled (network drops mid-transaction, retries), auth and data rules, and app-store readiness.

Questions buyers ask

How should a mobile app be built to launch in several countries?+
Treat each country as configuration: languages, currencies, payment methods, legal texts and feature flags come from data, not from code branches. Then a new market is a release of settings, not a rebuild.
Can an existing app be made accessible without a rewrite?+
In most cases, yes. An accessibility review lists the specific screens and components that fail WCAG checks, and most fixes are labels, focus order, contrast and touch-target sizes rather than structural changes.
What does a mobile architecture review usually find in a startup's app?+
A frequent finding is business logic living in the UI layer, for example payment validation inside view controllers or screens. The app works in a demo but every structural change touches many files. A review maps these couplings and proposes module boundaries before the first big third-party API change makes them expensive.

How it works

  1. Tell us what you need — the repo or system, the question, and the deadline.
  2. We match an expert from the network, with a second reviewer where it helps.
  3. Scoped work, contracted through Invental — review per pull request, a fixed-scope audit or architecture review, or ongoing capacity.
