Mobile App Development
Mobile apps your customers keep on their phones
We design and build apps for iPhone and Android, plus the servers behind them, and take them through app store review to launch.
Who this is for
Who we build this for
Businesses with repeat customers
Your customers book, order or check in often. An app puts you one tap away and lets you reach them with useful notifications.
Teams that work in the field
Technicians, drivers or inspectors need to see jobs, take photos and fill in forms on a phone, sometimes without a signal.
Startups with a mobile-first idea
Your product lives on the phone. You need a team that can ship both platforms, the backend and the store listings together.
A mobile app is two products at once: the app people hold in their hand, and the Backend that stores their data, sends notifications and talks to your other systems. Both have to be right. A beautiful app with a slow or fragile backend gets deleted.
For most businesses we recommend a cross-platform app built with React Native or Flutter, so one codebase serves iOS and Android and every feature ships to both at once. When an app needs deep access to device features or the smoothest possible performance, we build natively in Swift or Kotlin. Sometimes the best answer is not an app store app at all but a progressive web app that installs from the browser. We will tell you which fits before you spend money.
AI speeds up the parts that are similar in every app: screens built from your design system, API clients, form validation, offline storage and tests. People own the parts that decide whether the app succeeds: the flows, the feel on a real device, the handling of poor connections, and the privacy of the data the app collects.
We also plan for life after launch from the start. Phones update their operating systems every year, app stores change their rules, and users expect fixes quickly. That is why we set up crash reporting, analytics that respect privacy, automated builds and a simple release process before the first version ships. Your team, or ours, can then push an update in hours instead of days.
Data and privacy get the same care. We collect only what the app needs, explain it clearly in the store privacy details, keep secrets such as payment and AI keys on the server, and store sensitive data encrypted on the device. For apps in health, finance or education, we review the extra rules those categories face before we design the first screen, so there are no surprises during app store review or a security audit later.

What we build
Mobile app services
From the first screen to the app store listing.
Android apps
Native Android apps that work well across the wide range of phones your customers carry.

One codebase for iOS and Android with React Native or Flutter, so both apps ship together.
Progressive web apps
Web apps that install on a phone, work offline and send notifications, without an app store.
App backend and APIs
The servers, databases and APIs behind your app: accounts, data sync, notifications and payments.
App store launch
Store listings, review requirements, test builds and release management for the App Store and Google Play.
AI-accelerated
How AI speeds up this kind of work
AI does the repetitive work quickly. Experienced people make every decision that shapes the product.
-
AI doesReviews competing apps and their store reviews to list what users like and complain about.
People decideWhich problems your app solves first and what makes it worth installing.
-
AI doesGenerates screen variations from your design system and checks them against platform guidelines.
People decideThe final flows, the feel of every interaction and what stays off the small screen.
-
AI doesDrafts screens, API clients, local storage and push notification code.
People decideThe app architecture, offline behavior and how the app handles errors and slow networks.
-
AI doesWrites automated tests and helps reproduce bugs from crash reports.
People decideTesting on real devices, and whether the app is ready for the stores.
-
AI doesDrafts store descriptions, release notes and privacy disclosures.
People decideWhat you promise users and how their data is used.
Our process
Our process for this work
-
Step 1: Discover
We agree on the core use case, the platforms and whether native, cross-platform or web fits best.
-
Step 2: Design
Clickable prototypes you can try on your own phone before development starts.
-
Step 3: Build
App and backend built together, with test builds sent to your phone as features land.
-
Step 4: Launch
Store listings, review requirements and staged release, then monitoring of crashes and ratings.
Timeline and cost
What affects the timeline and cost
Every estimate starts from your scope. How we price work.
-
Platforms
One cross-platform codebase costs less than two native apps with the same features.
-
Backend work
Accounts, sync, payments and notifications often take as much work as the app itself.
-
Offline support
Apps that must work without a connection need careful data sync and conflict handling.
-
Device features
Camera, location, Bluetooth and background tasks each add build and testing time.
-
Integrations
Connections to your CRM, booking or payment systems add to the backend scope.
-
Store requirements
Some app categories, such as health or payments, face stricter review and privacy rules.

FAQ
Questions about mobile App Development
Have a question that is not here? Ask us directly.
For most business apps, cross-platform with React Native or Flutter gives you both platforms from one codebase at a lower cost. Native makes sense for heavy device features or demanding performance. We compare the options on your actual requirements during discovery.
It depends mostly on the number of screens and flows, the backend work and the integrations. The backend is often as large as the app. We give a fixed-scope estimate per milestone after discovery. Read how long an app takes to build for a sense of scale.
Yes. We prepare the listings, screenshots, privacy details and test builds, and we manage review feedback until the app is approved. See app store launch.
Yes. Common examples are reading receipts or documents with the camera, voice input, and an assistant that answers questions inside the app. We keep API keys on the server, never in the app. See AI product development.
Apps need regular updates for new OS versions, store policy changes and user feedback. We can stay on for ongoing development or hand over to your team with full documentation and access.
