Application Engineering

Custom Mobile Applications

We design and build native and cross platform mobile applications, from first release through App Store and Play Store approval to the updates that follow, engineered to feel fast and stay reliable on real devices, not just in a demo.

How We Build Mobile Applications

One team for iOS, Android, and everything that keeps users coming back.

Mobile application development at Devsinc covers native iOS and Android builds and cross platform apps, from the first prototype through app store submission and the update cycle that follows launch. Mobile is often where a business's AI work actually reaches a customer, so that capability is built in rather than left for a future release.

When we say custom mobile application, we mean an app engineered for the platform it runs on, native performance, offline behavior, push notifications, not a web view repackaged as an app. You own the app and its listing, we handle the engineering and the store approval process.

Capabilities

What this team actually delivers

01Native iOS DevelopmentSwift based apps built to Apple's platform conventions and performance expectations.

02Native Android DevelopmentKotlin based apps built for the fragmented device and OS landscape Android developers actually face.

03Cross Platform DevelopmentReact Native or Flutter builds for teams that need one codebase across iOS and Android without sacrificing native feel.

04Mobile Backend and API IntegrationThe services, sync logic, and offline handling that keep the app working with unreliable connectivity.

05On Device and Cloud AI FeaturesCamera based recognition, voice interfaces, personalization, and predictive features, running on device where latency matters or in the cloud where scale matters.

06App Store Launch and OptimizationStore listing preparation, submission, and the review process for both Apple and Google.

07Post Launch Maintenance and UpdatesOS version support, bug fixes, and feature updates after release, mobile apps break silently when this is skipped.

Process

How the work runs

01Requirements and PlanningUnderstanding target platforms, offline and connectivity needs, and store requirements before development begins.

02Architecture and PrototypeDesigning the app architecture and prototyping the core user flows before full development.

03Development and TestingBuilding in short, reviewable increments, with device testing across the OS versions your users actually run.

04Launch and SupportManaging app store submission and review, then maintaining the app through OS updates and new feature releases.

FAQs

Frequently Asked Questions

Still have a question about platforms, offline support, or the app stores?

Let's talk

How long does a typical mobile app project take?+

Most mobile projects run three to six months from kickoff to store launch, depending on platform scope and feature complexity.

Should we build native or cross platform?+

Depends on your priorities. Native gives the best performance and platform specific feel, cross platform gets you to both iOS and Android faster from one codebase.

Do you handle App Store and Play Store submission?+

Yes, including preparing the listing, navigating the review process, and handling rejections if they come up.

What happens after launch, do you maintain the app?+

Yes, mobile apps need ongoing updates for new OS versions and device changes, we offer post launch support rather than a one time handoff.

Can the app include AI features such as recommendations or image recognition?+

Yes. Common patterns include on device machine learning for speed sensitive features and cloud based AI for anything that needs a larger model.

Can the app work offline or with poor connectivity?+

Offline data handling and sync logic are architected in from the start where the use case requires it.

How do you keep user data secure?+

Encrypted data in transit and at rest, secure authentication, and compliance with platform and industry specific requirements.
