What we deliver
Full-lifecycle app development, nothing outsourced
Design, backend, native and cross-platform builds, QA, store submission and maintenance all live in-house. We do not hand the design to one agency and the build to another. One team owns your app from first sketch to live release to version two, and you always have one point of contact.

How we work
Our mobile app development process
Seven stages, each with a visible output you can review and approve before the next one begins. No black box between idea and the app store.
- 01
Discovery
We map your users, goals, platforms and the constraints before recommending an approach.
- 02
Design
Wireframes through to a polished, tested UI you sign off before a line of app code.
- 03
Architecture
Platform choice, backend, data model and integration plan agreed and documented.
- 04
Development
Clean, native-quality code built in reviewable sprints with builds you can try each week.
- 05
Testing
Testing on real iOS and Android devices, plus performance, security and accessibility.
- 06
Launch
We handle App Store and Play submission, review wrangling and a monitored release.
- 07
Support
Monitoring, OS-update readiness, fixes and new features long after launch day.
Why choose us
An app team that owns the whole journey
Most shops build and disappear. We design it, build it, get it through store review and keep it alive as the platforms change. We push back on scope that will not earn its keep and stay reachable long after launch.
Talk to us-
Idea to store, one team
Design, build, test, submit and maintain. One accountable team owns the whole journey, not just the coding.
-
Native and cross-platform
Swift, Kotlin, React Native and Flutter. We recommend the right approach for your budget, timeline and performance needs.
-
Performance you can feel
Smooth scrolling, fast launch and no jank. We treat app performance as a requirement, not a nice-to-have.
-
Design that earns the rating
App store ratings are won on experience. Research-led UX and polished UI are part of every build.
-
Tested on real devices
We test on actual phones and tablets across OS versions, not just simulators, before anything ships.
-
We handle store submission
App Store and Play review can be a maze. We prepare, submit and get your app approved without the back-and-forth.
-
Security and privacy built in
Secure storage, proper auth and privacy compliance designed in from the start, essential on mobile.
-
Alive after launch
Apps need care as iOS and Android evolve. We stay on to keep yours current, stable and improving.
Questions, answered
Mobile app development FAQs
Should I build native or cross-platform?
Native (Swift for iOS, Kotlin for Android) gives the best performance and platform feel, ideal for graphics-heavy or platform-specific apps. Cross-platform (React Native or Flutter) ships both platforms from one codebase, faster and more cost-effective for most apps. We recommend based on your app, budget and timeline rather than defaulting to one.
How much does it cost to build a mobile app?
Most app projects land between $15,000 and $120,000. A focused single-platform app sits at the lower end; a complex app with a backend, multiple platforms and integrations sits higher. Every quote is scoped and itemized before work begins.
How long does it take to build an app?
A focused app typically takes 10 to 20 weeks from design to store. Larger or enterprise apps run longer. You see designs early and a working build every week, so you watch it come together.
Do you build for both iOS and Android?
Yes. We build native for each platform, or cross-platform with React Native or Flutter to serve both from one codebase. We will advise which approach fits your goals and budget best.
Do you handle App Store and Play Store submission?
Yes. We prepare store listings, assets and metadata, handle the submission and manage the review process, including resolving any rejections, so your app gets approved and live.
Do you design the app or just build it?
Both. We offer research-led UI/UX design from wireframes to a polished, tested interface and a reusable design system, or we can build from your existing designs. Design is core to how we work.
Can you build the backend too?
Yes. Most apps need APIs, a database, authentication and push notifications. We build the backend and the app together so they fit perfectly, or integrate with your existing systems.
What happens after the app launches?
Apps are living products. iOS and Android release updates that can break things, and users expect improvements. Most clients move to a maintenance plan covering monitoring, OS-update readiness, fixes and new features.
Have an app idea? Let's make it real.
Describe what you want to build in plain language. We will tell you the right platform, the realistic cost and how long it will take, usually within one business day.
