Services

iOS and Android app development

iPhone and Android apps that share logic and design with your website. One team, one codebase, two app stores, without paying twice.

What is included

What the work includes

  1. 01

    An app for your customers

    Orders, payments, notifications, loyalty and support in one app. Works offline too: what has already loaded opens instantly.

  2. 02

    An app for your staff

    Couriers, field technicians, sales reps: tasks, routes, photos and signatures from a phone, with the data landing straight in your back office.

  3. 03

    Backend and admin panel

    An app does not live on its own: we build the backend, the admin panel and the integrations with CRM, payments and notifications.

  4. 04

    Publishing and updates

    We take the app through App Store and Google Play review, set up automated builds and ship updates without downtime.

Who it is for

A good fit if

  • Customers come from their phones and the website is awkward for that
  • You need push notifications, location, camera or offline work
  • Your staff work in the field, not at a desk
  • You have a website and need an app with the same account and data

What we build with

  • React Native
  • Expo
  • TypeScript
  • Node.js
  • NestJS
  • PostgreSQL
  • Keycloak
  • Sentry
