01

What is slowing your business down?

Identify repetitive tasks, missing information, and steps where work stalls. We use those needs to build a solution for your team.

01

Bookings and orders take too many messages

Customers wait for a reply to check availability, place an order or change a booking. Your team handles each step manually.

02

Field work returns as paperwork

Photos, job details and signatures arrive through separate messages. Office staff spend time collecting and entering them again.

03

Customers lose touch after the first visit

Your service has no convenient place for repeat purchases, loyalty benefits or relevant updates that customers choose to receive.

02

What we can build for your business

01

Bookings and purchases in a few taps

We build availability, reservations, ordering and payments into one mobile journey, making it easier for customers to complete the next step.

02

A connected field team

Work orders, photos, signatures and offline records let employees complete tasks on site and share them with the office when connected.

03

Give customers a reason to return

Accounts, loyalty benefits, subscriptions and optional notifications keep your service accessible between visits.

04

Manage the service behind the app

Your team gets an administration area for users, orders, content and reports. We connect existing systems and prepare the app for store release.

03

Is this the right approach?

It fits when

  • The phone’s camera, location, notifications, biometrics, or offline capability matters.
  • Frequent customer or field use benefits from a dedicated app experience.
  • A mobile product supports a validated business process or product model.
  • You can identify one core workflow that makes the first release valuable.

Consider a simpler option first when

  • A responsive web application covers the complete use case.
  • The product depends on an unvalidated audience but has no launch or acquisition plan.
  • The first release includes several unrelated user journeys with equal priority.

04

From business problem to maintainable product

Each stage ends with a concrete decision, keeping scope, cost, and responsibility visible.

  1. 01

    Validate the mobile use case

    Confirm why an app is better than responsive web and identify the first repeatable user outcome.

  2. 02

    Choose native or cross-platform

    Compare performance, device access, team, platform behavior, timeline, and long-term maintenance.

  3. 03

    Design, build, and test the core loop

    Prototype the experience, connect the backend, and test on a defined real-device matrix.

  4. 04

    Release in controlled stages

    Use internal and beta tracks before store production, then monitor stability and product signals.

Frequently asked questions

How much does a mobile app cost?

A focused cross-platform first release commonly starts around €12,000. Products with payments, complex backend workflows, offline data, hardware, or several roles often start around €35,000.

How long does it take to build an app?

A focused first release usually takes 8–16 weeks. Larger products are safer to split into staged releases across four to eight months or more.

Should we choose native or cross-platform?

Cross-platform is often efficient when iOS and Android share most product behavior. Native is stronger when platform-specific interaction, hardware access, performance, or independent platform roadmaps dominate.

Who owns the App Store and Google Play accounts?

The client should own both developer accounts. The delivery team can receive the access needed to prepare and submit releases without controlling the business accounts.

Can you build the backend too?

Yes. Mobile scope can include authentication, APIs, database, notifications, administration, analytics events, and integrations needed by the app.
