Why teams call us

An app that works, until it meets a real phone

Most of what we're asked to fix is an app that was built for a demo, not for production use.

It works on the demo device, not in the field

Poor connectivity, older devices and real-world usage patterns weren't part of the test plan.

The web version is an afterthought

A responsive layout that technically works, but nobody would call it a mobile experience.

App store rejections keep happening

Submission requirements were missed, and every resubmission costs another review cycle.

Capabilities

What we build

The right approach depends on your users, not a default technology choice.

iOS & Android apps

Native where performance matters, cross-platform where it doesn't — we'll tell you which fits.

Cross-platform builds

React Native or Flutter for one codebase across iOS and Android, without sacrificing feel.

Progressive web apps

Installable, offline-capable web apps for teams who don't want an app store dependency.

App store submission

Store listings, screenshots and compliance requirements handled, including resubmissions.

Push notifications & offline support

Sync that survives patchy connectivity, and notifications that actually reach users.

Performance optimisation

Startup time, memory usage and battery impact tuned for real devices, not flagship phones.

How we work

From wireframe to app store

Most builds go from first call to a submitted app in four to ten weeks.

STEP 01

Define the platform fit

Native, cross-platform or web — decided against your users and budget, not a default stack.

STEP 02

Build in sprints

Two-week sprints with a working build on your own device at the end of each one.

STEP 03

Test on real devices

Older phones, patchy networks and edge cases — not just the simulator.

STEP 04

Submit & launch

Store submission handled end to end, including any resubmissions.

Engagement models

Questions we're asked before starting

Anything else, write to us and an engineer will answer.

admin@cybexsoft.com
Native or cross-platform — which do we need?+

Depends on what the app does. Camera-heavy, high-performance or platform-specific apps usually want native; most business apps do well cross-platform. We'll give you a straight answer.

Do you handle app store submission?+

Yes, including developer account setup, store listings and any resubmissions after review feedback.

Can you take over an existing app?+

Often. We start with a short audit of the codebase and give an honest recommendation before any new work starts.

Who owns the app once it's built?+

You do — the code, the store listing and the developer account all stay in your name.

Do you offer ongoing app maintenance?+

Yes, as a monthly retainer covering OS updates, bug fixes and small feature work.

Have an app idea, or one that needs fixing?

Tell us what it needs to do and who it's for, and we'll reply within one business day with a rough shape of the work.
