Let’s talk
Mobile Development

Apps that hold up on the devices people actually own

We build native iOS and Android products that go the distance, handling the parts that go wrong after launch: release processes, device fragmentation, offline behavior, and performance on hardware from four years ago. Because a great app isn't just the one you ship, it's the one that keeps working long after.

What mobile app development covers

Native iOS and Android craftsmanship, plus the platform-specific engineering every mobile product needs, no matter the framework.

Native iOS

Built beautifully with Swift, SwiftUI and UIKit.

Native Android

Kotlin, Jetpack Compose and the Android SDK.

Release engineering

App Store and Play Console submission, review handling, phased rollout, versioning.

Device and OS coverage

Fragmentation, screen sizes, OS version support and hardware differences.

Offline and sync

Local persistence, conflict resolution and background sync.

Hardware and platform APIs

Camera, Bluetooth and BLE, biometrics, location, push, widgets and wearables.

*

For cross platform work from a single codebase, that's Flutter. → Flutter Development

How we work it

01

Platform decision, made with care

Native or cross-platform, chosen based on what your product truly needs and the team who'll maintain it.

02

Releasing from day one

A distributable build by week one, so we catch submission surprises early, not late.

03

Test on real devices

Emulators miss what matters most: performance on older hardware, camera behavior, connectivity, battery life.

FAQs

Still have some doubts?
No worries, here are some frequently asked questions that may help you.

Native or cross platform?

It depends on what the product needs from the hardware and on who will maintain it. Cross-platform from one codebase covers most products and is where our depth is. Native is the right call when you depend heavily on platform specific APIs or on performance at the edge of what the hardware can do. We've recommended both.

How much does mobile app development cost?

It depends on scope, platforms and integrations, and we give you a number after a scoping conversation. Anyone quoting before that is guessing.

Do you handle App Store and Play Store submission?

Yes, including review rejections, phased rollout, certificate and signing management, and the requirement changes both platforms introduce regularly.

Can you work on our existing app?

Yes, starting with a review of the codebase, the dependencies and the release setup.

What about wearables and connected devices?

Yes. We've shipped for Wear OS and for Huawei smartwatches, and we work with Bluetooth and BLE for hardware connected products.

How do you test on real devices?

A device lab covering the OS versions and hardware your users actually have, because that's where performance and camera and connectivity problems appear.

Tell us about the app

New build, existing codebase, or a release that keeps getting rejected. We'll tell you what we'd do about it.
