iOS and Android app development

Mobile app development for iOS and Android.

Pyalm builds mobile apps for customers, field teams, and shop floors: one codebase for iOS and Android, a reliable backend, and the offline behaviour real-world connectivity demands.

Business outcomes

One codebase, two stores

Ship to iOS and Android together with a shared codebase, cutting build and maintenance cost.

Works where connectivity does not

Offline-first data means sales, inspections, and deliveries keep working in basements, warehouses, and remote sites.

A backend you can grow on

Secure APIs, authentication, sync, and admin tools designed alongside the app, not bolted on afterwards.

What we can deliver

A complete, usable solution—not an isolated feature.

  • App strategy, feature prioritisation, and UX design
  • Cross-platform iOS and Android development with React Native and Expo
  • Offline-first local storage and background cloud sync
  • Backend APIs, authentication, roles, and admin dashboards
  • Payments, barcode scanning, camera, location, and push notifications
  • App Store and Play Store submission, updates, and monitoring

Cross-platform by default, native where it matters

For most business apps, React Native with Expo gives native performance and access to the camera, barcode scanner, location, and notifications from one codebase — roughly halving the cost of maintaining separate iOS and Android apps. We drop to native modules only where a feature truly needs it. See React Native vs Flutter vs native for the full comparison.

Offline-first: our specialty

Many apps assume a constant connection and fail at the worst moment. We build apps where the local database is the source of truth: every action saves on the device instantly and syncs to the cloud in the background, with clear conflict rules across multiple devices. That is how Pyalm POS keeps shops billing during outages, and it is the right design for van sales, inspections, deliveries, and events.

Apps we have shipped

  • Pyalm POS — offline-first billing with credit sales, collections, analytics, and multi-device sync
  • Pyalm Split — an expense tracker with group splits, analytics, and offline sync
  • Pyalm Books for Android — mobile access to invoicing and accounting

Delivery approach

Clear decisions from discovery through improvement.

Scope, evidence, and ownership remain visible throughout the project so the finished system can be operated—not just demonstrated.

01

Define

Agree users, core journeys, offline needs, integrations, and the first store release.

02

Design

Prototype key screens and validate them on real devices with real users.

03

Build

Develop app and backend together in releases, with automated builds for both stores.

04

Launch & support

Handle store review, crash monitoring, over-the-air updates, and the next release.

Frequently asked

What to know before we begin.

Do you build for both iOS and Android?

Yes. We build cross-platform apps with React Native and Expo, which ship to both stores from one codebase, and add native modules where a feature requires them.

Can the app work offline?

Yes. Offline-first design is a core strength: data is stored on the device, the app works without a connection, and changes sync automatically when connectivity returns.

Do you handle App Store and Play Store publishing?

Yes. We prepare store listings, privacy declarations, builds, and review submissions, and set up over-the-air updates for fast fixes.

How long does it take to build an app?

A focused business app with a backend typically takes 8 to 16 weeks for a first store release, depending on features, integrations, and offline requirements.

Can you build the backend and admin panel too?

Yes. We deliver the API, database, authentication, admin dashboard, and hosting together with the app.
