Apps that feel native, on every phone.
A mobile app lives in your user's pocket — it has to be fast, feel right, and never get in the way. We build native iOS and Android apps (or cross-platform when that's the smarter call) that turn your design into something people actually keep on their home screen.
Where it fits
Build · after design. Mobile App Development takes the app Product Design creates and makes it real on iOS and Android. After launch, Product Support keeps it healthy and Product Optimization sharpens it.
Who it's for
Teams launching or rebuilding a mobile app — a startup shipping its first product, or an established team that needs an app that finally feels native on both platforms.
What you get
- Native iOS and Android — or one cross-platform codebase when it fits
- The backend and APIs that power the app
- Push notifications, realtime data and deep links
- Offline support and performance tuned for real-world networks
- App Store and Play submission, shepherded through review
- QA on the real devices your users actually hold
What we do
From first build to store launch — each technique is a card, pulled live from our Techniques library.
iOS Development
Native iPhone and iPad apps that feel at home on iOS.
- What
- Swift / SwiftUI builds following Apple's guidelines.
- How
- Native implementation from the design, tuned to iOS conventions.
- Purpose
- iOS users expect iOS-native — anything less feels off.
- When
- For iPhone and iPad products.
Android Development
Native Android apps across the device landscape.
- What
- Kotlin builds following Material guidelines.
- How
- Native implementation tuned to Android conventions and devices.
- Purpose
- Android's diversity rewards a build made for it, not ported to it.
- When
- For Android products.
Cross-platform Development
One codebase, both stores, when it's the right call.
- What
- React Native or Flutter builds for iOS and Android together.
- How
- Shared codebase with native modules where they matter.
- Purpose
- For many apps, cross-platform ships faster at the same quality.
- When
- When speed and budget favor one codebase.
App Backend & API
The services that power the app.
- What
- APIs, data sync, auth and the backend behind the app.
- How
- Reliable services built to scale with your users.
- Purpose
- An app is only as good as the backend feeding it.
- When
- Alongside the app build.
Push & Realtime
Bringing users back, and keeping data live.
- What
- Push notifications, realtime updates and deep links.
- How
- Implemented and tested across both platforms.
- Purpose
- Push is the channel that re-engages users who left.
- When
- Where engagement and live data matter.
Offline & Performance
Fast and usable, even on a bad connection.
- What
- Offline support, caching, smooth performance and battery.
- How
- Built for real-world networks and devices, then measured.
- Purpose
- Mobile users are on the move — the app has to keep up.
- When
- Throughout the build.
App Store & Play Submission
Getting you live on both stores, cleanly.
- What
- Store listings, review compliance, signing and release.
- How
- Prepare, submit and shepherd through review on both stores.
- Purpose
- A rejected submission delays a launch by weeks.
- When
- At launch and each update.
Mobile QA & Device Testing
Tested on the phones your users actually hold.
- What
- Functional, UI and edge-case testing across devices and OS versions.
- How
- Real-device and simulator testing across the matrix.
- Purpose
- “Works on my phone” isn't a test plan.
- When
- Throughout, and before each release.
The full mobile stack — native where it counts, cross-platform where it's smart.
Native-quality, both platforms
An app that feels ported is an app users delete. We build to each platform's conventions — the gestures, the transitions, the small things iOS and Android users expect — so it feels like it belongs on their phone, not like a website in a shell.
AI in the app
AI-assisted development
AI speeds the repetitive build so engineers focus on the native detail.
AI features in-app
Copilots, smart search and personalization, designed to feel native, not bolted on.
How it runs
Mobile App Development is project-based, scoped to your app.
From $1,500 · 1–4 months, depending on platforms and complexity.
Backed by fifteen years, 50+ products shipped, and 30M people served a month.
Questions, answered
Yes — native iOS (Swift) and native Android (Kotlin), each built to its platform's conventions. When budget and timeline favor it, we also build cross-platform (React Native or Flutter) for both stores from one codebase.
It depends on your app. Native gives the best feel and access to platform features; cross-platform ships faster and cheaper for many apps. We recommend the right call for your product, not a default.
We build from a finished app design — yours or one we create in Product Design. Pairing the two means the app that ships is exactly the app that was designed.
Yes — listings, signing, review compliance and release on both stores. We shepherd the app through review so a rejection doesn't cost you weeks.
From $1,500, over 1 to 4 months, depending on platforms and complexity. Tell us about the app and we'll give you a clear scope, number and timeline.
Product Support keeps the app healthy — OS updates, fixes and new releases — and Product Optimization improves it against real usage. An app is never “done”; we keep it shipping.
