Service · Mobile app development

Mobile apps that extend your digital system into your clients' pockets.

We don't build apps so you can say you 'have an app', but as a logical extension of the system that already exists: website → bookings / inquiries → CRM → mobile app. The focus is on scenarios where a mobile app genuinely makes life easier for guests, clients, and your team.

  • • iOS and Android apps connected to the existing system
  • • Use cases tied to real processes, not to 'nice to have'
  • • Emphasis on stability, UX, and measurable results
  • • Specialized experience in tourism, rent-a-car, and real estate
  • • Integration with the website, API, CRM, and internal tools
  • • Focus on functionality, not empty notifications

A mobile app makes sense only when we know exactly what it needs to do: who it's for, in what situations it's used, and how it connects with the rest of your digital system.

Who is this service for

Mobile apps for teams that care about concrete impact, not just an icon in the Store

  • • hotels and apartments that want to offer guests quick communication, additional services, and loyalty programs through an app
  • • rent-a-car agencies that need an app for bookings, check-in, vehicle pickup, and client communication
  • • real estate teams and investors who want buyers and agents to have project information 'at their fingertips'
  • • businesses with clear backend processes that want to move part of that experience to the mobile channel

We might not be the best fit if:

  • • you're looking for a generic 'white-label' app without customization to your process
  • • you want an app just for image, without a clear usage plan and goals
  • • it's not important to you that the app is connected to existing systems
  • • you expect a complex app with minimal budget and without your team's involvement

Key elements

Mobile apps as an extension of the backend system, not another isolated channel

Instead of developing apps 'separately', we build them as a front end for what already exists or needs to exist behind the scenes — website, API, CRM, booking systems, and internal tools.

Defining use case scenarios

Who uses the app, in what situations, and what they need to do in a few taps — including push notifications, QR code access, and offline mode.

UX and screen structure

Screen architecture and user flows tailored to your business type, languages, and user habits.

Backend and integrations

Connecting to the existing API, CRM, booking systems, billing, and internal tools — or building a new backend layer.

Publishing and maintenance

Preparation for App Store and Google Play, app analytics, versioning, technical support, and further feature development based on real usage.

Recognizing the situation

Do you actually need a mobile app — or should the system be fixed first?

The most common signs that an app makes sense (or that it's not the right time yet):

'Guests / clients constantly ask us the same things'

You're frequently repeating the same information via email, phone, or messages — an app can take over a large portion of these interactions.

'The field team works on paper, Viber, and Excel'

Operations (e.g., drivers, maintenance, property tours) don't have a central tool for daily work.

'We have a web system, but want a better mobile experience'

There's a backend and website that work well, but the mobile part of the experience is weak or nonexistent.

'We're not sure if we actually need an app'

You have an app idea, but it's not clear whether it will be used — that's where the discovery phase comes in, before development.

Hotel with improved direct bookings

Coastal hotel — more direct bookings

A website redesign and channel manager integration led to a rise in direct bookings and lower portal commissions.

Example: +27% direct bookings in the first 6 months.

Rent-a-car fleet displayed on website

Rent-a-car fleet — less manual work

A centralized system for vehicles, pricing and availability reduced duplicate entries and calendar errors.

Example: up to 40% less manual work in operations.

Collaboration steps

How we go through mobile app development

The goal is for the app to be a logical extension of the system — not an experiment nobody uses. In practice, the project goes through these phases:

  1. 1

    Discovery and priorities

    Together we define use case scenarios, target users, main features, and what's 'MVP' vs. what can wait.

  2. 2

    UX, architecture, and backend logic

    We sketch screens and flows, and agree on how the app connects with existing systems — or plan a new backend layer.

  3. 3

    Development, testing, and launch

    Development of iOS and Android versions (React Native or Flutter), PWA option for a faster start, integrations, test phase with your team, and store publishing — with a clear roadmap for what comes next.

About us

Leovac Digital as your web + mobile ecosystem partner

Over 15 years of experience in web development, booking systems, and custom platforms — plus mobile app development connected to those same backends.

We don't view the app separately from the website and system. The goal is one ecosystem: shared data, clear processes, and an experience that feels natural in both the browser and on the phone.

Budgets and collaboration models

Estimated costs for mobile app development

The price depends on feature complexity, integrations, and number of languages / markets. These are the ranges most projects fall into — excluding costs of third-party services (push, map services, etc.).

Discovery and specification

Workshops, defining the MVP, use case scenarios, and technical architecture — before development begins.

Typically in the range of 600-1,500 EUR one-time.

MVP app connected to the system

iOS and Android app with key features and integrations with the existing backend.

Typically in the range of 4,000-10,000 EUR, depending on scope.

Further development and maintenance

New features, market adaptation, technical updates, and continuous ecosystem development.

Retainer models typically 800-1,500 EUR per month.

The final proposal depends on app scope, integrations, and plans for the next 6-12 months — we define it after a discovery phase or at least a brief system review.

FAQ

Most common questions before mobile app development

Do we actually need a mobile app?

If you can achieve most of your goals with a good web system and optimized processes, we'll honestly say so. An app makes sense when it brings additional value in specific use case scenarios.

Do you build native or hybrid apps?

We typically do cross-platform (e.g., React Native) with a focus on iOS and Android — connected to a backend that already exists or that we build.

What's needed from our team?

We need access to existing systems, a person responsible for the business side, and people who will actually use the app — so we can validate flows together.

Who publishes the app to the stores?

We can publish through your Apple/Google accounts or help you set them up — with preparation of all necessary materials (screenshots, text, descriptions).

What if we already have a backend / API?

Great. In that case, we focus on UX, screens, and integration with your existing API, with suggestions for improvements where needed.

Quick idea and system review

Request a review of your app idea and existing system

We go through your idea, existing processes, and tools — and honestly say whether a mobile app is a logical next step, or if it's smarter to fix other parts of the system first.

  • • brief diagnostics of current system and app idea
  • • identifying key use case scenarios
  • • recommendation on whether and what kind of app makes sense
  • • priorities for the next 90-180 days (with or without an app)

A review doesn't mean a commitment to app development — the goal is to make a more informed decision together, before a major investment.

No obligation. If we determine we're not a good fit, we'll say so openly.
