App development

Mobile and web applications

We design and build mobile apps (Android, iOS), web applications and custom-built apps. From idea and UX, through development, to launch and ongoing growth.

Apps that support your business

Building a great app isn't just about choosing the technology - it's also about delivering a positive user experience. We design apps that are intuitive, fast and genuinely enjoyable to use.

We run the project from workshops and wireframes, through visual design, all the way to launch and ongoing growth.

How we work on apps

UX/UI design

We start with the user's needs. Wireframes and prototypes let us test the app before a single line of code is written.

Choosing the technology

We select the tech stack to fit the project's real requirements, budget and growth plans.

Integrations

We connect the app with your systems, payments and analytics so everything runs in one ecosystem.

Performance and stability

We ensure speed and reliability across different devices and as your user base grows.

Store deployment

We support publishing to the App Store and Google Play and configuring the production environment.

Ongoing growth

We develop new features based on data and user feedback.

Types of apps

App development built around specific business goals

We build apps around a specific business goal - from mobile apps to web solutions and dedicated custom builds.

Mobile apps

Mobile app development for Android and iOS, including cross-platform technologies.

Web applications

Web apps and panels that run in the browser - available anywhere, with no installation.

PWA

Progressive web apps that combine the reach of a website with the convenience of a mobile app.

Custom applications

Dedicated, custom-built apps designed around your company's individual processes and integrations.

Process

From idea to a working app

We work in stages, with a clear quote up front and ongoing updates on progress.

Technologies and integrations

A tech stack chosen to fit the goal

We don't start by choosing the technology, but by defining the goal. Only then do we select the tools that fit it best - so the app is fast, secure and ready to grow. We rely on proven, well-supported technologies, which keeps the code stable and means you aren't locked in to a single vendor.

Cross-platform apps

A single codebase for Android and iOS shortens time and cost to launch. Where maximum performance matters, we reach for native solutions.

Integrations and APIs

We connect the app with your systems: CRM, ERP, payments, logins, maps or databases - through secure, well-documented APIs.

Analytics and data

We plug in analytics tools so we can grow the app based on real user behavior.

Security and GDPR

Data encryption, secure authentication and GDPR compliance. We protect user data at every stage - from design to maintenance.

Case study

Interactive tariff calculator: taniej.tauro-dystrybucja.pl

For taniej.tauro-dystrybucja.pl we designed and built a web application with an interactive calculator and a tariff comparison tool. How does it work? The user enters their energy usage, and the tool instantly calculates the cost across different tariffs and points to the most favorable option.

  • Interactive energy cost calculator
  • Tariff comparison tool working in real time
  • Responsive interface - working on phone, tablet and desktop
  • Integration with the client's tariff data

Use cases

Who do we build apps for?

An app makes sense wherever a repeatable process can be simplified, sped up or made available online. Here are examples of the apps we most often build for companies and institutions.

Business apps

Tools that support sales, customer service and everyday processes in your company - from quoting to order management.

Internal apps

Panels and systems for teams: document workflows, tickets, reporting and task management in one place.

Customer-facing apps (B2C)

Apps for end users: accounts, push notifications, loyalty programs and convenient shopping.

Calculators and configurators

Interactive tools, like the tariff comparison for taniej.tauro-dystrybucja.pl, that help customers make a quick decision.

Panels and dashboards

Clear, real-time data views - metrics, charts and reports brought together in one easy-to-read interface.

E-commerce and bookings

Online stores, carts and payments, plus booking, registration and appointment-scheduling systems.

Why us

Specifics, not promises

We combine design, technology and marketing - for us, an app is part of a company's strategy, not just another IT project.

Frequently asked questions

App development - questions and answers

How much does it cost to build a mobile app?

The cost depends on the scope of features, the platforms (Android, iOS) and integrations. We prepare a quote after an initial conversation with the client to understand their expectations.

How long does it take to build an app?

A simple MVP usually takes a few to several weeks, while more complex apps take longer. We work in stages and keep you updated on progress throughout.

Do you build apps for Android and iOS?

Yes. We build apps for both platforms, including in cross-platform technologies, as well as web applications.

How does a mobile app differ from a web app?

A mobile app is installed on a phone (Android, iOS), while a web app runs in the browser. The choice depends on your goal and audience.

Do you handle growth and maintenance after launch?

Yes. We offer development, updates and technical support after the app goes live.

Do you also design UX/UI?

Yes. We design the interface with the user experience in mind before the development stage even begins.
