Overview

A business app is software your staff, customers or partners use every day to get a specific job done: placing and tracking orders, booking appointments, logging work in the field, approving requests or checking account status. It can run in the browser as a web app, on phones as a mobile app for iOS and Android, or both, sharing one backend and one database. We help you pick the right form for your users, design the screens with you and develop the whole system, including the admin side your team works in.

We do not only develop apps for others - we also run our own. Radne Nedjelje, our web and mobile app, is used by more than 300,000 people a month, so we know what it takes to keep an app fast, stable and up to date long after release. You get a fixed quote in writing within 5 working days of our first call, we reply to every enquiry on the same working day, and the code is yours once the work is paid for.

When it makes sense

What our app development includes

06
  1. 01

    Web apps

    Applications that run in any browser, with no installation: dashboards, booking and order systems, back-office tools and admin panels.

  2. 02

    Mobile apps for iOS and Android

    One cross-platform codebase for both systems, or native apps where the device demands it, with push notifications, offline mode and camera or location access.

  3. 03

    Business apps for your team

    Apps for field staff, warehouses, sales and management: work orders, checklists, approvals and reports, available on phone and desktop.

  4. 04

    Customer and partner portals

    Secure accounts where customers place orders, track status, download documents and contact you, without calling your team.

  5. 05

    MVPs for new products

    A first working version with only the features you need to test the idea with real users, built so it can grow without starting over.

  6. 06

    Publishing and maintenance

    App Store and Google Play submission, monitoring, security and OS updates, bug fixes and new features after release.

How we work

  1. Research

    We talk through your users, the problem the app solves and the systems it has to connect to, and within 5 working days you get a written scope and a fixed quote.

  2. Design

    We design the key screens and user flows, and agree on the platforms, data and architecture before development starts, so you see the app before it exists.

  3. Build

    We develop in short iterations, and you get test versions on your own phone and in your browser early, so feedback arrives while changes are still cheap.

  4. Operate

    We publish the app to the stores and the web, monitor it, keep it compatible with new iOS and Android versions, and keep developing it as your needs change.

Questions

06 Q
  1. 01 How much does app development cost?

    It depends on what the app has to do. The main price drivers are the platforms (web, iOS, Android or all three), the number of screens and features, user roles and permissions, integrations with your existing systems, how custom the design is, and the maintenance you need after release. That is why we do not publish a price list. The first call is free: we go through your idea, and within 5 working days you get a fixed quote in writing, so the price is known before any work starts. Smaller changes and maintenance are billed at an hourly rate of €40-60.

  2. 02 How long does it take to develop an app?

    A focused business app or a first version of a new product usually takes from a few weeks to a few months, depending on the number of features, platforms and integrations. We prefer to release a smaller first version early and add features afterwards, so you start getting value sooner. Your written quote includes a timeline with clear milestones.

  3. 03 Web app or mobile app - which should I choose?

    A web app is the right choice when users work mostly at a computer, when you want instant updates without app store reviews, or when the app is used occasionally. A mobile app makes sense when people use it on the move, need push notifications, offline access, the camera or location, or open it every day. Many businesses need both: a mobile app for customers or field staff and a web admin panel for the office. We will recommend the option that fits your users, not the most expensive one.

  4. 04 Do you develop apps for both iOS and Android?

    Yes. In most cases we develop one cross-platform app that runs on both iOS and Android from a single codebase, which keeps development and maintenance affordable. Where an app depends heavily on device features or demanding performance, we develop native apps instead. We also handle publishing to the App Store and Google Play, under your own developer accounts.

  5. 05 Who owns the code and the app?

    You do, once the work is paid for. The source code, designs and documentation are handed over into your repositories, and the app is published under your App Store and Google Play accounts and your domain. Third-party and open-source components keep their own licences. You can continue development with us, with your own developers or with another vendor.

  6. 06 Do you maintain the app after release?

    Yes. We offer monthly maintenance and development: monitoring, security updates, compatibility with new iOS, Android and browser versions, backups, bug fixes and new features. The scope follows what your app actually needs, and smaller changes outside the agreed plan are billed by the hour. We run our own apps the same way, so we know what keeps an app working long after release.
