Home / Services / App Development and LaunchService 01 · For app makers

App development, from first idea to App Store launch.

We design, build and launch mobile apps using the same process we follow for our own products. You get a working app, a store-ready listing and a team that has published many apps before.

What is included

What we do for you.

Planning and scoping

Turn your idea into a clear feature list, screen map and plan, so you know what will be built before work starts.

UI/UX design

Flows, screens and a simple brand look, checked in prototypes before any code is written.

Building and testing

AI-assisted development that people review and test on real devices. Our experience is mainly with iPhone apps.

App Store submission

Store listing, screenshots, privacy details and submission, handled the way we handle our own apps.

Launch and updates

Fixes and improvements after launch, guided by reviews and usage numbers.

Websites and web apps that go with your app

A fast, search-ready website or web app when your product needs one.

How it works

Four clear steps.

Discover

We listen, check the market and agree what the first version should do.

Design

Screens and flows are designed and reviewed with you before building.

Build and test

The app is built in stages, with a working version you can try along the way.

Launch and improve

We prepare the App Store submission, then improve the app from real feedback.

Deliverables

What you receive.

Scope document

Feature list, screen map and plan in plain language, agreed before any build starts.

Clickable prototype

The main flows to tap through on a phone, so you can change your mind cheaply.

Working builds

A test version you can install and try at each stage, not one reveal at the end.

Store-ready submission

Listing text, screenshots, privacy details and the build, prepared for App Store review.

Handover

Source code, accounts and a short guide, so the app stays yours.

From our own apps

Built on real work.

We publish and update our own apps, including BibleHi, PlantFollow, Music Player and Video Player, and we maintain a shared code base across 100+ Bible apps. The way we plan, test and submit your app is the way we handle ours.

Ways to work together

A fixed-scope project, or a monthly arrangement for ongoing updates.

What we need from you

A clear idea of who the app is for, your content or brand if you have it, and one person who can decide.

Not included

Developer account fees, paid third-party services and ad budgets are paid by you directly.

Tools we use

Prototyping and design tools, AI coding assistants reviewed by people, and real-device testing.

Questions

About this service.

Do you build apps for clients?

Yes, on a limited basis. Marberx is a product company first, so we take a small number of projects at a time. Write to us and we will tell you honestly whether we are a good fit.

Do you build Android apps?

Our experience is mainly with iPhone apps on the Apple App Store. Tell us what you need and we will say plainly whether we can help.

How long does it take to build an app?

It depends on the features. We give a timeline after we understand your idea, and we put it in writing.

Can you help me publish an app that is already built?

Yes. We publish and maintain many apps, and can help with the store listing, review preparation and launch.

Do you use AI to build apps?

Yes. We use AI coding tools to move faster, and people review, test and take responsibility for the result.

How much does an app cost?

Cost depends on scope. We share a clear estimate after we understand your project.
