Mobile App Development for iOS and Android
Mobile app development for iOS and Android. React Native, Flutter, native solutions. From prototype to app store deployment.
Mobile apps are smartphone programs (iOS and Android) built natively or cross-platform with frameworks such as React Native or Flutter.
Challenge
Your company wants to reach customers on mobile devices, but building separate apps for iOS and Android is expensive and time-consuming. You need a solution that works on both platforms.
Our Solution
We build mobile applications using React Native and Flutter, enabling code sharing between platforms. We design intuitive UX/UI interfaces, integrate with backend APIs, and deploy to App Store and Google Play.
Result
A mobile app running smoothly on iOS and Android, published in app stores. Fast, responsive, and integrated with your backend systems.
Which mobile apps we build
We build apps that solve a concrete business problem - for customers, partners or your team. We most often create:
- B2C apps: stores, loyalty programmes, service apps for your customers
- B2B and internal apps: tools for salespeople, technicians and field staff
- Companion apps for web systems: mobile access to your platform or panel
- Apps with integrations: payments, maps, push notifications, code scanning
In most projects we favour cross-platform technologies (React Native, Flutter), which deliver one app for iOS and Android from a single codebase - at a lower cost than two separate native apps.
How a mobile app project runs
We run a mobile app from idea to store publication, in stages that give you control over scope and budget.
- Discovery: we set the goals, the audience and the key features of the first version
- UX/UI design: wireframes and a clickable prototype before any code is written
- Development: we build the app and connect it to the backend and external services
- Testing: we check behaviour on real iOS and Android devices
- Publication: we prepare the assets and take the app through App Store and Google Play requirements
We usually start with an MVP carrying the most important features, then grow it after launch based on real user data.
Cross-platform or a native app?
This is one of the first questions in a mobile project - and one worth answering deliberately rather than out of habit.
- Cross-platform (React Native, Flutter): one codebase for both platforms, lower cost and faster delivery; ideal for most business apps
- Native (Swift, Kotlin): when the app heavily uses hardware, needs maximum performance or specific system features
In practice, for the vast majority of companies cross-platform delivers the same result for the user at a significantly lower cost. We advise honestly - if your case calls for native, we will say so plainly.
Publishing and maintenance in the stores
Launch is not the end but the start of an app's life. We help you through the store requirements and keep the app healthy after release.
- Publication in the App Store and Google Play in line with their guidelines
- Setup of developer accounts, certificates and push notifications
- Updates for new iOS and Android versions so the app does not stop working
- Monitoring of errors and performance on users' devices
- Growth with further features based on feedback and data
The stores change their requirements regularly - we keep your app compliant and available to users.
What you gain from a mobile app
A well-designed mobile app is a permanent channel to your customer and easier work for your team.
- A direct channel to customers - with push notifications instead of lost emails
- Convenience and speed that build loyalty and repeat use
- Access to company tools in the field, offline where needed
- One codebase for iOS and Android - lower maintenance cost than two apps
- Data on real usage that helps you make better decisions
We treat the app as a product meant to deliver a business result, not just to "be in the store".
How much a mobile app costs
The cost depends on the number of features, integrations and whether the app runs in one country or globally. A simple MVP is a project measured in weeks; an extensive product with many integrations is quoted individually and split into stages.
We bill on a Time & Material basis at 120 PLN/h net, with full transparency of the hours. We first define the MVP scope so you reach the market faster on a controlled budget.
After launch we offer care from 1,000 PLN net per month - updates for new OS versions, monitoring and the development of further features.
Frequently Asked Questions
For most business apps, yes. React Native and Flutter let you write one app running on both platforms, which lowers cost and speeds up delivery. Where maximum performance or specific hardware features matter, we recommend a native solution.
A simple MVP usually takes several weeks; an extensive product with many integrations is split into stages. After analysing the requirements we present a realistic schedule and the scope of the first version.
Yes. We prepare the app in line with store guidelines, set up developer accounts and certificates, and take the app through the whole publication process.
Apps need updates for new iOS and Android versions so they don't stop working. We offer post-launch care covering updates, error monitoring and the development of further features.
