Mobile App Development Services

Native iOS and Android apps built for small businesses. Every project includes both platforms, App Store submission, and ongoing support. See our development process or view pricing.

Companion Apps

A companion app extends your platform website into a native mobile experience. Your existing content, products, or services become accessible through an app that lives on your customers' home screens — not just their browser tabs.

Built on your site's REST API, companion apps stay in sync with your website automatically. Update a post, change a price, add a product — it shows up in the app without any extra work.

  • iOS + Android from one codebase
  • REST API integration
  • Push notification support
  • Offline mode capability
  • App Store & Play Store submission
  • Matches your website branding
  • Ongoing maintenance & updates included

Loyalty & Rewards
Order & Delivery
Staff / Internal Tools

Business Utility Apps

Standalone apps built around a specific business function. A booking app reduces phone tag. A loyalty app brings customers back. An ordering app handles sales at scale. Purpose-built tools that solve one problem exceptionally well — for your customers or your staff.

Building for a specific industry? See our pages for restaurants, ecommerce & retail, salons, spas & fitness, contractors & trades, and healthcare & wellness.

API-Connected Apps

Apps that pull live data from external sources — your site, a payment processor, a booking system, or a custom API we build specifically for your project.

Whether you need real-time inventory updates, payment processing through Stripe or Square, or integration with your existing CRM, we build the connection layer so your app always has the latest data.

  • REST API integration
  • Third-party API connections
  • Custom back-end development
  • Real-time data synchronization
  • Secure authentication & token management

Technologies we use

Every app we ship runs on React Native with Expo — a proven cross-platform stack that produces native iOS and Android apps from a single codebase. Here's what's under the hood on every project:

Considering a no-code alternative? See how we compare to Bubble, Adalo & FlutterFlow →

React Native
Cross-platform native apps for iOS and Android from one shared codebase. Same performance, same feel — one project, both stores.
Expo
Managed build pipeline, over-the-air updates, and access to native device APIs — NFC, camera, push notifications, biometrics, and more.
SQLite (offline-first)
Local database storage for apps that need to work without a connection. Data is available on-device instantly, with sync capabilities when online.
REST API
Built-in integration with any site. Your existing content, products, and users connect to the app without extra plugins in most cases.
TestFlight & Play Console
Every app goes through real-device beta testing via TestFlight (iOS) and Google Play Console (Android) before any store submission.
App Store & Google Play
We handle the full submission pipeline for both stores — metadata, screenshots, review response, and approval management from start to finish.

Frequently asked questions

A companion app typically takes 4–6 weeks. A Business Utility app (booking, loyalty, ordering) runs 8–12 weeks. Full app + website bundles range from 10–20 weeks depending on scope. See our full development process →
