As an app development company in Poland, we design and build apps for iOS and Android — from an MVP that validates the idea to mature products with thousands of users. We publish to the App Store and Google Play, then keep developing the app with you. A team based in Szczecin, with clients across Poland and abroad.
That is the first question every client asks. The answer depends on the product — we will help you decide at the start, because it affects the budget and the timeline.
One codebase for iOS and Android. Lower build and maintenance costs — 30–40% less than two separate apps. The right choice for most businesses.
Maximum performance and full access to the hardware. It makes sense for games, AR/VR and heavy use of the camera and sensors.
A cross-platform core with performance-critical modules built natively. Good for growing products.
We are a software house from Szczecin, Poland. Our office is at Marszałka Józefa Piłsudskiego 37/10 — you can book a meeting here or talk to us online. One team designs and builds your app, from the estimate through to publication on the App Store and Google Play, with no subcontractors and no middlemen.
We also build apps for companies across Poland and abroad — most of our projects run remotely. Need a website rather than an app? See websites.
Every bespoke mobile app is more than a set of screens on a phone:
A mobile app usually relies on your data and on external services: accounts and sign-in, payments, push notifications, analytics, offline working with synchronisation, and a connection to your system via an API.
Rates: development €46/h net, design €35/h net. Realistic price ranges:
Euro amounts converted at the NBP mid-market rate of 14 September 2026 (€1 = 4.3391 zł) and rounded. We invoice in PLN.
Remember the fixed costs: an Apple account at USD 99/year, Google at USD 25 one-off, and a server for a modest monthly fee. Maintaining an app typically costs 15–25% of the build cost per year.
The price range is the sum of hours of work times the rate. Below is the indicative effort for the app's foundation and typical features — the same values our cost calculator uses.
| App component | Hours | Cost, net |
|---|---|---|
| Interface design, up to 5 screens | 28 – 58 h | €980–2,030 |
| Development of the app foundation, up to 5 screens | 85 – 210 h | €3,910–9,660 |
| Accounts and login | 10 – 26 h | €460–1,200 |
| Online payments | 12 – 30 h | €550–1,380 |
| Bookings and calendar | 14 – 34 h | €640–1,560 |
| Chat and messaging | 10 – 26 h | €460–1,200 |
| Push and email notifications | 6 – 18 h | €280–830 |
| Admin panel | 20 – 46 h | €920–2,120 |
| Maps and geolocation | 3 – 8 h | €140–370 |
| CRM integration | 8 – 26 h | €370–1,200 |
| Integration with an ERP or warehouse system | 16 – 44 h | €740–2,020 |
| AI and automation | 16 – 44 h | €740–2,020 |
Design and the foundation grow with the number of screens: 5–15 screens means a multiplier of 1.7, more than 15 — 2.6. Language versions add 8–40 hours, an urgent deadline a 20% surcharge, and ready-made mock-ups in Figma cut design hours roughly fivefold.
Up to 5 screens, interface design from scratch, login, bookings and push notifications. An illustration only, not an offer:
| Item | Hours | Cost, net |
|---|---|---|
| Interface design | 28 – 58 h | €980–2,030 |
| Development of the app foundation | 85 – 210 h | €3,910–9,660 |
| Login, bookings, push | 30 – 78 h | €1,400–3,600 |
| Total | 143 – 346 h | €6,250–15,300 |
The calculator rounds this to approx. €6,200–15,300 and estimates the delivery time for this scope at 8–14 weeks. The amount fits within the MVP range — the rest depends on which features go into the first version.
Class timetable, one-tap class booking, membership pass on your phone and children's accounts linked to a parent's number. On the App Store and Google Play since September 2026.

An application for an aviation platform: a flight simulator with VR headsets, 3D aircraft models, a motion platform and real-time flight telemetry.
View project →“Working with CodePort has been an excellent experience. They built an application for our aviation platform using a flight simulator with VR headsets. The team showed strong technical knowledge, delivered clean, well-organised code and maintained clear, proactive communication throughout the project. Delivered on time and to a high standard — we definitely recommend them as a reliable and professional IT partner.”

Almost always with an MVP. Choose the one feature that will make a user download the app, and build it properly. A working product will fund the rest. More in our article →
Google Play usually approves an app in 1–3 days. The Apple App Store takes anywhere from one day to a week, sometimes with comments to address. We prepare the full set of assets and go through the review for you.
If you need it to — yes. We design data synchronisation and a local database so that the app works without a connection and sends changes once it is back online.
iOS and Android release major updates every year. An app left unattended starts to “break”. That is why we offer ongoing support — library updates, testing on new system versions and fixes.
The number of screens and features, whether you need your own backend and admin panel, and which platforms are involved. As a guide: an MVP costs ca. €6,000–15,700 net (excl. VAT), a mid-sized app ca. €9,700–25,400 net (excl. VAT), and a full-scale product from ca. €23,000 net (excl. VAT). We have set out the full cost breakdown in our article on how much a mobile app costs.
Yes. Our office is at ul. Marszałka Józefa Piłsudskiego 37/10 in Szczecin — you can arrange a meeting in person or talk online.
Yes. We can sign an NDA even before the first conversation, and we base our cooperation on a contract and billing in stages. Once all stages have been accepted and all invoices paid, full intellectual property rights to the code and design pass to you, and the code goes to your repository.
A mobile app has the advantage when users reach for it every day on their phone, and the product needs push notifications, offline working or camera access. A web app runs in the browser, with no app store publication and no developer accounts — it works well for admin panels and systems for teams. See web applications.
Yes. We run most projects remotely, in Polish, English, German, Ukrainian or Russian, for clients in Poland and abroad.
