Custom Mobile App Development Services for iOS, Android & Cross-Platform
Vortex provides custom mobile app development services for enterprise workforce and customer apps. We build native iOS and Android apps and cross-platform apps in React Native and Flutter that work offline, distribute through MDM and sign in with your existing SSO. As an enterprise mobile app development company, we plan the release process, device support and integrations along with the app itself.
What we deliver
A mobile project here includes the app itself, the backend it depends on and the way it reaches devices. We deliver all of it.
Enterprise workforce apps
We build apps for inspection, dispatch, logistics, clinical and retail teams. These people work at the edge of the network, sometimes in gloves, on limited bandwidth or in harsh conditions, and the app has to work reliably there.
Enterprise customer apps
Customer-facing apps cover account management, order management, booking, loyalty programs and customer service. We build them natively or on top of your systems of record and business platforms. This work also includes ecommerce mobile app development, where we build shopping apps for your customers.
Cross-platform apps in React Native or Flutter
Our cross platform mobile app development services use React Native or Flutter when you want one shared codebase that still gives each device an appropriate native experience.
Native iOS and Android apps
We go native with Swift, SwiftUI, Kotlin, Jetpack Compose and related tools when the app needs advanced hardware access, top performance or deep platform integration. For teams looking for an iOS mobile app development company, this covers iPhone and iPad apps built in Swift and SwiftUI.
Mobile backend services
The APIs and backend services are built for mobile from the start. That covers synchronization, push notifications, delta processing and payload design.
Device integrations
Apps can talk to cameras, barcode and RFID scanners, GPS, Bluetooth/BLE, NFC, biometrics, printers and other compatible hardware. For offline and device-heavy apps we define local storage and queued actions first. Then come the sync and conflict rules, the permissions, and the screen a user gets when a scanner drops out or the network is gone.
Enterprise app distribution
We deliver through MDM/EMM platforms such as Intune, Jamf and Workspace ONE, and handle private distribution, enrollment and provisioning.
Legacy app modernization
When users are stuck on a legacy mobile app, we move them to a maintainable replacement and plan the risk and cost of the transition up front.
Where enterprise mobile goes wrong
Enterprise mobile development is rarely about the app on its own. The hard part starts when the finished product has to work in the field, on mixed devices, for different user groups, against several backend systems.
Offline connectivity
Sync conflicts
Identity and access
Distribution
Release velocity
The backend
Native, cross-platform or both: when to use each
The best enterprise mobile app development platform is the one that fits the app's hardware needs, performance targets and long-term maintenance plan. We help you pick based on those, and the reasoning goes into the architecture document.
Cross-platform (React Native or Flutter)
Cross-platform works best when the UI is fairly simple, the app is data-driven, both platforms need similar features and a shared codebase helps your team move faster. Many enterprise workforce apps fit that description. React Native is a good fit for these apps, and so is Flutter.
Native (Swift or Kotlin)
Native is the better choice for apps that need deep hardware integration, critical performance or the newest platform capabilities. Some clinical apps and apps with AR or heavy sensor use fall here.
A mix of the two
An app can use native components for specific UI controls or hardware features and build the rest in a cross-platform framework.
Our guide to native vs cross-platform app development covers the tradeoffs in more depth.
How custom mobile app development services run
One team covers the backend, the app, distribution and support, so each step below is handled by the same engineers.
Mobile architecture assessment · about 2 weeks
We look at requirements, users, devices and backend readiness, make the platform decision with you, and finish with a delivery plan that has a real number in it.
Architecture and planning · 2–3 weeks
This is where the offline data model, sync and conflict rules, identity, API contracts, distribution model and testing approach get decided and written into the delivery plan.
Build in two-week increments
We build the app and backend together, in increments you can release, monitor and test on real devices.
Device and distribution testing
Automated and device testing with tools such as XCTest, Espresso, Appium, Detox, Firebase Test Lab and BrowserStack. MDM enrollment and private publishing are tested before rollout.
Staged release
Whether it goes through the app stores or MDM, we roll the app out in stages so problems surface with a small group first.
Support or handover
We maintain the app under a managed services contract, or set up maintenance and update procedures so your team can run it.
How to choose a custom mobile app development company
Other questions worth asking:
-
Who builds the backend and APIs? For us, the same team that builds the app.
-
Who owns the code? You own the source code, infrastructure definitions and documentation, subject to the contract.
-
Can our team maintain it after launch? Yes. We use mainstream technologies with good documentation, or we keep maintaining it for you.
-
Will the people on the first call write the code? Yes. The engineers who scope the work are the ones who build it.
Technology stack
We choose between mobile app development platforms based on product requirements, infrastructure, device capabilities, security and long-term maintenance.

Frequently asked questions
What drives the cost of a custom mobile app
These are the questions our estimator asks, because each one moves the number.
-
The biggest one is how much has to work offline. An app that runs a full shift without signal needs a local database, queued actions and conflict rules. Read-only offline access costs less.
-
Platform scope comes next: iOS, Android, one shared codebase, or a managed tablet or handheld fleet. Each scanner, printer, BLE or NFC device then adds its own integration and testing work.
-
Identity and backend readiness are often underestimated. Matching corporate SSO, session rules, device restrictions and entitlements takes real effort, and so does building APIs the app needs when they don't exist yet.
-
Distribution matters too. A managed MDM fleet, staff-owned phones, the public app stores or a mix of them each change the release work.
