About This Service

Mobile apps from a single codebase

Cross-platform development means one codebase serving iOS and Android, roughly halving both build cost and the ongoing burden of keeping two apps in step. We use native modules where performance genuinely demands it, handle App Store and Play Store submission including the review process, and build offline tolerance in from the start because mobile users are frequently on unreliable connections.

Mobile apps from a single codebase
Cross-platform done pragmatically
Why Choose Chambrix

Cross-platform done pragmatically

One codebase for most apps, with native modules reserved for where performance truly needs them.

Cross-Platform Build

One codebase for iOS and Android, with native modules used where performance actually requires them.

Offline Tolerance

Local caching and queued actions, so the app remains usable when the connection drops.

Store Submission

Listings, assets, review responses and release management handled end to end.

What one codebase returns

Lower cost, consistent releases and apps that work on poor networks.
Roughly Half The Cost
One codebase instead of two separate native builds, with proportionally lower ongoing maintenance.
Consistent Across Platforms
Features ship to iOS and Android together rather than one platform waiting behind the other.
Works On Poor Networks
Offline handling keeps the app usable in the conditions mobile users are frequently in.
No Store Guesswork
We handle submission and rejections, which are common and time-consuming for first-time publishers.

How Mobile App Development Works

The same four stages on every project, so you always know what happens next.

  1. Platform Strategy

    We confirm cross-platform genuinely fits your requirements, and recommend native where it does not.

  2. Design & Prototype

    Platform-appropriate interface design, prototyped and tested on real devices rather than in a browser.

  3. Build & Test

    Development with testing across a device matrix covering the screen sizes and OS versions you support.

  4. Submit & Support

    Store submission, review handling, launch monitoring and a support window for post-release fixes.

Mobile App Development — Questions

Straight answers to what clients ask most

Cross-platform or native?
Cross-platform suits the large majority of business apps at roughly half the cost. Native is worth it for graphics-intensive apps, heavy background processing or deep platform-specific integration.
How long does store approval take?
Typically one to seven days per submission. First submissions are rejected more often than not, usually over metadata or privacy declarations rather than the app itself, so we build that into the schedule.
Do you handle app store optimisation?
Yes. Listing copy, keywords, screenshots and preview video, since store search is a major discovery channel for most apps.
What about ongoing maintenance?
Both platforms release annual OS updates that can break apps. We offer maintenance retainers covering compatibility updates, security patches and store policy changes.
