02 / Built around your ambition
Our mobile app development services — 8 Trusted Solutions
- 01
Native iOS (Swift, SwiftUI)
We build iOS apps in Swift and SwiftUI with UIKit where needed, following Apple's design guidelines for apps that feel at home on iPhone and iPad.
- 02
Native Android (Kotlin, Jetpack Compose)
We build Android apps in Kotlin with Jetpack Compose, handling the wide range of device sizes and OS versions your users actually run.
- 03
Flutter cross-platform development
We use Flutter to deliver iOS and Android from a single Dart codebase, keeping pixel-consistent design across both platforms with one product team.
- 04
React Native with shared web logic
We build React Native apps that share business logic and types with your web product, letting JavaScript teams contribute across mobile and web.
- 05
Ionic + Capacitor for content/utility apps
We use Ionic and Capacitor for content and utility apps where web skills and fast delivery matter more than heavy native interaction.
- 06
App Store Optimisation (ASO)
We research keywords, write listing copy, produce screenshots and preview videos, and run store listing experiments to improve visibility and conversion.
- 07
Crashlytics, Sentry, Firebase Analytics
We wire in Crashlytics, Sentry and Firebase Analytics with alerts and dashboards, so crashes and usage trends are visible from the first release.
- 08
App Store + Play Store release pipelines
We set up automated builds, signing, TestFlight and Play testing tracks and staged rollouts, with all accounts registered in your company's name.
The Payoff
What Our Mobile App Development Services Give You
The right technology for your app
We match native, Flutter, React Native or Ionic to your features, budget and team rather than defaulting to one tool.
Accounts in your name
Apple Developer and Google Play Console accounts, signing keys and repositories belong to you from day one.
Store listings that get found
App Store Optimisation is planned before launch, with keywords, screenshots and descriptions ready for release day.
A plan beyond the MVP
We design the first version so it can grow into a larger product without a rewrite.
How we work / From idea to impact
How We Deliver Mobile App Development Projects
- 01
Product workshop
We clarify who the app is for, the core tasks it must handle and what success looks like after launch.
- 02
Platform and architecture choice
We recommend native or cross-platform based on your feature list, device needs and future plans, and explain why.
- 03
UX and interface design
Clickable prototypes are tested with real users so navigation and key flows are settled before development.
- 04
Development sprints
The app is built in short sprints with test builds shared through TestFlight and Play internal testing.
- 05
Store submission
We prepare listings, privacy details and screenshots, then handle App Store and Play Store review.
- 06
Monitoring and iteration
After release we track crashes, reviews and usage, then plan updates based on what users actually do.

Mobile app development services in 2026 require a different kind of agency than 2016 — apps now compete with millions of others on the App Store and Google Play, and the cost of a buggy launch is permanent. Devintek ships mobile apps for B2B field service tools, consumer fitness, healthcare admin, education, fintech onboarding, content creators and B2B2C marketplaces. Every mobile engagement starts with a paid two-week discovery sprint that ends in a clickable Figma prototype, a written platform recommendation (native vs Flutter vs React Native vs Ionic), a technical architecture document and a fixed-scope quote. From there we ship in fortnightly sprints with named senior engineers — Swift/SwiftUI specialists for iOS, Kotlin/Compose specialists for Android, dedicated Flutter or React Native engineers for cross-platform — and weekly TestFlight or Internal Testing builds for client review. Observability (Crashlytics or Sentry, Firebase Analytics or Mixpanel, performance traces) is wired in before launch. App Store Optimisation (keyword research, conversion-optimised screenshots, preview video production, listing A/B testing) is part of scope, not an upsell. Every app we deliver includes documented architecture, automated test coverage on critical paths, a CI/CD pipeline on Xcode Cloud, Bitrise or GitHub Actions, and full account ownership transfer to the client on day one. We also run mobile maintenance retainers for apps we did not originally build — typically stabilising apps via structured audits, observability rollout and release-cadence resets.
