mobile application development
Armdia Systems provides mobile application development from the United Kingdom. Typical engagements run from GBP 35,000 to GBP 120,000 and last eight weeks to six months. Work is delivered by named senior engineers with written scope, documented handover and security review built into the delivery process.
iOS, Android, Progressive Web Applications, tablet variants and device specific companion apps where hardware or store distribution demands it.
React Native with Expo is preferred for shared delivery. SwiftUI and Kotlin with Jetpack Compose are used where native performance or platform APIs are central.
We handle provisioning, signing, review notes, test builds, store listings and resubmission when Apple App Store or Google Play asks for changes.
A focused cross platform app starts near GBP 35,000. A full featured product often sits near GBP 80,000. Two native apps can exceed GBP 120,000.
Use this table to choose the right starting point before a discovery call.
| Model | Typical use | Commercial shape |
|---|---|---|
| Audit | Assess an existing product, risk or architecture | Fixed price written report |
| Build phase | Design and ship a scoped product or feature set | Fixed price after discovery |
| Retainer | Keep a product healthy after launch | Monthly reserved capacity |
| Option | Best fit | Risk to check |
|---|---|---|
| Armdia Systems | Bespoke systems with clear ownership and United Kingdom first delivery. | Requires a proper discovery phase before fixed pricing. |
| Off the shelf SaaS | Standard workflows with little custom process risk. | Licence, integration and process mismatch costs can grow. |
| Freelance contractor | Small isolated tasks with limited governance needs. | Continuity, documentation and support coverage need scrutiny. |
Cross platform through React Native is preferred when both iOS and Android are needed and the app does not depend on platform specific hardware. Native Swift or Kotlin is chosen when performance, camera, sensors or platform design guidelines are central.
We write review notes, prepare test accounts, address guideline requirements before submission and handle resubmission when Apple or Google asks for changes. Most rejections are resolved within one resubmission cycle.
Yes. Every build is tested on physical iOS and Android devices before submission. Emulator testing is used during development but is never the final test before release.
Yes. Progressive Web Applications are a strong choice when store distribution is not required and the app does not need deep hardware access. They are cheaper to build and maintain.
Push notifications are implemented through Firebase Cloud Messaging for Android and Apple Push Notification Service for iOS. React Native libraries abstract both where cross platform delivery is needed.
Support covers crash monitoring, store listing updates, operating system compatibility patches, small feature releases and analytics review. Monthly retainers keep the app healthy after launch.
