What We Deliver

Web & Mobile App Development Capabilities

Web Application Development

We build customer portals, dashboards and SaaS front ends with React and Next.js, backed by typed APIs and automated tests.

  • React and Next.js apps
  • TypeScript across the stack
  • Server-side rendering and caching
  • Role-based access and SSO

Flutter App Development

We ship iOS and Android apps from one Flutter codebase when you need both platforms without doubling the team or the timeline.

  • Single codebase for iOS and Android
  • Native plugins where needed
  • Offline data and sync
  • App Store and Google Play releases

Native iOS & Android

When an app depends heavily on device hardware, platform UI conventions or demanding performance, we build natively in Swift and Kotlin.

  • Swift and SwiftUI for iOS
  • Kotlin and Jetpack Compose
  • Bluetooth, camera and sensors
  • Push notifications and deep links

Progressive Web Apps

We build installable web apps that load quickly, work on poor connections and reach users without an app store download.

  • Service workers and offline caching
  • Installable home-screen apps
  • Web push notifications
  • Core Web Vitals tuning

Headless Commerce & API Integrations

We connect your apps to the systems your business runs on, from headless Shopify storefronts to payments, CRMs and ERPs.

  • Headless Shopify storefronts
  • Stripe and payment gateways
  • CRM and ERP integrations
  • REST and GraphQL APIs

App Maintenance & Support

We keep apps secure and compatible after launch with dependency updates, OS release testing, monitoring and a planned feature backlog.

  • iOS and Android version updates
  • Security patches and dependency upgrades
  • Crash and performance monitoring
  • Ongoing feature development

Who we build for

We work with startups preparing a first release, SaaS companies extending their product to mobile, and established businesses replacing spreadsheets and legacy portals with software their customers and staff actually want to use. Typical situations include:

  • A validated idea that needs a real product. You have customer interest and need a production-quality web app or mobile app, not a throwaway prototype.
  • A slow or outdated web application. Page loads drag, the front end is hard to change, and each release breaks something.
  • Two platforms, one budget. You need iOS and Android apps but cannot fund two separate native teams.
  • Disconnected systems. Orders, customers and inventory live in different tools, and staff re-enter data by hand.
  • An app without an owner. The original developers moved on and the app needs updates for new OS versions and security patches.

As a web app development company with mobile experience on the same team, we can deliver the web portal, the mobile apps and the APIs behind them as one coordinated project.

Our engineering approach

Choosing the right stack

For web applications we default to React and Next.js with TypeScript because they give fast page loads, strong SEO for public pages and a large hiring pool for your future team. For mobile app development services, we compare Flutter and native development against your feature list. Flutter app development is usually the efficient choice for business apps that need both platforms; Swift and Kotlin win when hardware access or platform-specific behavior matters most.

Quality built into every sprint

Every change goes through code review and automated tests: unit tests for business logic, integration tests for APIs, and end-to-end tests for critical user flows such as sign-up and checkout. We use CI pipelines to build and test every pull request and to distribute mobile builds to TestFlight and Google Play internal testing, so stakeholders can try features on real devices during development.

Performance and security

We track Core Web Vitals on web apps, keep mobile bundle sizes and startup times in check, and add crash reporting and performance monitoring before launch. Security basics are standard: authenticated APIs, role-based permissions, secrets kept out of source code, dependency scanning and secure storage of tokens on devices.

Designed before it is built

Good apps start with clear flows. For products that need deeper research, design systems or usability testing, our UI/UX design team works alongside developers so designs are practical to build and consistent across web and mobile.

Engagement models

  • Fixed-scope project. Best for an MVP or a well-defined feature set with clear acceptance criteria.
  • Dedicated product team. A cross-functional team of developers, QA and a project lead working through your roadmap sprint by sprint.
  • Maintenance retainer. Planned hours each month for updates, OS compatibility, bug fixes and small improvements to a live app.

What influences cost and timeline

The biggest drivers are scope and platform count. Each additional user role, integration or platform adds design, development and testing effort. Other factors include real-time features such as chat or live tracking, offline support, payments, complex permissions, and regulatory needs such as HIPAA or PCI considerations. Existing APIs that are well documented speed things up, while undocumented legacy systems add discovery time. Where the backend needs significant new business logic, we scope it with our custom software development practice, and we can host and run the result through our cloud services.

Why EvoxSoft

  • One team for web, mobile and backend. Fewer handoffs, shared API contracts and consistent behavior across platforms.
  • Working software every sprint. Demos and test builds instead of status reports.
  • You own the code. Your repositories, your store accounts and your intellectual property.
  • Support after launch. We plan for maintenance from the start so the app stays secure and compatible with new OS releases.

FAQ

Frequently Asked Questions

Do you build web apps with Laravel, Vue or Angular, or only React?

All of them. We build web applications with React and Next.js, Vue and Nuxt, Angular, and PHP with Laravel, and mobile apps with Flutter, React Native or native Swift and Kotlin. We recommend a stack based on your team's skills, performance needs and long-term maintenance, and we are happy to continue an existing Laravel, Vue or Angular project.

How much does it cost to build a web or mobile app?

Cost depends on the number of screens and user roles, integrations with third-party systems, whether you need web, iOS, Android or all three, and any compliance or offline requirements. A focused first release costs much less than a full feature set, so we usually recommend starting with an MVP. We share a detailed estimate after a discovery call.

How long does app development take?

A focused MVP typically takes a few months from kickoff to launch, and larger platforms are delivered in phases. The biggest timeline factors are scope, integration complexity and how quickly decisions and feedback come back. You see working software every sprint, so progress is never a surprise.

Should we choose Flutter or native iOS and Android?

Flutter is a strong choice when you need both platforms with a shared codebase and a consistent UI. Native Swift and Kotlin make more sense when the app depends on deep hardware access, platform-specific UI, or demanding performance. We recommend an approach after reviewing your feature list rather than by default.

Do we own the source code?

Yes. You own the source code, designs and intellectual property created for your project, as stated in our contract. Code lives in your repositories, and app store listings and cloud accounts are set up under your organization.

Can you take over an existing app built by another team?

Yes. We start with a code and architecture review to understand quality, test coverage, dependencies and risks. From there we propose either incremental improvement or targeted rewrites of problem areas.

What engagement models do you offer?

We offer fixed-scope projects for well-defined builds, dedicated teams for ongoing product development, and monthly maintenance retainers for live apps. Many clients start with a fixed-scope MVP and move to a dedicated team after launch.
