app development

App development for Android and iOS that people genuinely love.

An app is not just "a website with an icon". We build fast, stable, comfortable mobile apps - for field workers, for your customers, or for an internal process - from the idea all the way to the store.

overview

An app that fits the way you work

Not every business needs an app, but when it does, it has to work brilliantly. We start with the questions of who the app is for and which core action it needs to make simple and fast, and only then do we build.

Whether it is an app for field workers that runs even without a signal, a customer service app, or an internal tool for your team - we build it to be fast, secure and pleasant for daily use.

what's included

What the app development service includes.

From the first idea to an app that sits in the store and runs smoothly on every device.

Specification and screen flow

We map every screen and every action so the app is simple and self-explanatory.

Mobile UX/UI design

A clean interface built for the thumb and the small screen, not a shrunken website.

Android and iOS

One codebase that serves both platforms, saving time and maintenance costs.

Works offline too

The app keeps working with no internet and syncs once the connection is back.

Connects to your systems

Data flows between the app and your management system with no double entry.

Store publishing and support

We guide you through publishing on Google Play and the App Store and the updates that follow.

    Development and QA

    We build, test thoroughly, and show you a beta version to try before go-live.

  4. 4

    Go-live and support

faq

Frequently asked questions.

How much does it cost to develop an app?

It depends on the scope and the number of screens. After the specification stage you get a clear proposal, and the initial consultation comes with no cost and no commitment.

Do you need to build separately for Android and iOS?

Not necessarily. In most cases we build with a technology that serves both platforms from a single codebase, which makes development cheaper and faster.

Can the app connect to a system we already have?

Yes, this is one of our specialties - connecting via API to your management system or your existing systems.

What about updates after launch?

We support you with updates, fixes and additions, as well as adaptations for new versions of Android and iOS.

How long does it take?

An initial app with the key functions can go live within a few weeks, then expand from there.
