I build mobile apps for businesses in Białystok and across Poland - remotely, with a fixed price before any code is written. A cross-platform MVP for iOS and Android starts at €6,000. A full product with payments, user accounts and an admin panel runs €12,000-€25,000. From kickoff to App Store and Google Play: 4 to 8 weeks.
Białystok is the economic center of northeastern Poland - food industry, wholesale trade, logistics, and a growing services sector. The apps I build here tend to fall into practical categories: field tools for warehouse and delivery teams, loyalty and ordering apps for restaurant and retail chains, booking systems for healthcare and wellness businesses, B2B dashboards for companies managing distribution across the Podlasie region. Each project gets a fixed scope before the build starts - not a rough estimate that shifts every two weeks.
What building a mobile app actually involves
A mobile app is three connected things: the screens on the phone, the backend with a database and API, and the store submission to App Store and Google Play. Depending on what your Białystok business needs, it might look like:
- A loyalty app with points, push notifications, and a digital customer card.
- A field worker tool with QR scanning, delivery confirmations, and route-based assignments.
- A booking app for a medical clinic, beauty salon, or fitness facility.
- An ordering app for restaurants, pharmacies, or wholesale suppliers.
In every project I deliver: screen design, frontend, backend, external integrations, store submission under your accounts, one month of post-launch support.
Concrete prices and timelines
I quote in EUR per fixed scope, not per hour.
MVP - €6,000-€12,000
Login, the core feature set, one or two integrations, push notifications. Delivered in 4 to 6 weeks. A real product you can put in front of users - not a clickable prototype or a demo video.
Full product - €12,000-€25,000
Payments (Stripe, Przelewy24, BLIK), user accounts with history, admin dashboard, several integrations. Two to four months. Most serious projects land here: ordering apps for local restaurant chains, field tools for logistics companies, booking platforms with CRM sync.
Complex product - from €30,000
Marketplace logic, real-time chat, geolocation, offline sync, complex role and permission models. Quoted in phases.

React Native vs native - the decision that moves your budget most
React Native builds both iOS and Android apps from one codebase. For 80-90% of business apps, it is the correct choice: 30-60% cheaper than two separate native builds, one codebase to maintain long-term. My default.
Native development in Swift and Kotlin means two separate codebases - roughly double the build cost and double the ongoing maintenance. It earns its price only in specific cases: games, heavy AR, high-frequency camera use, or deep background Bluetooth and sensor work. A wholesale company in Białystok building an ordering and inventory tool does not need native.
The practical test: does your app manage orders, accounts, notifications, and data lists? React Native. Does it need to push hardware sensors at maximum throughput in the background? Then native.
How the work goes
A 30-minute scoping call first. You get a written fixed scope and a fixed price - no hourly surprises mid-build. Work starts after signing and a deposit. Weekly progress updates throughout, not just a final handover.
The app ships under your developer accounts: Apple Developer ($99 per year, paid directly to Apple) and Google Play ($25 once). After launch I monitor App Store Connect and Play Console for 30 days and handle any technical issues.
I work with Białystok clients remotely - no in-person meeting is required at any stage. If your business serves clients across the Podlasie region or into Baltic markets, multilingual support can be built in from the start rather than added later.
Why a solo senior over a local agency
Białystok does not have a large mobile agency market. That means your realistic choice is a national agency with significant overhead, an unknown freelancer, or a senior developer who owns the project end-to-end. Working directly with a senior cuts the PM and account manager layer - the people you would rarely actually talk to at an agency - without cutting the quality.

FAQ
How much does mobile app development cost in Białystok? A cross-platform MVP starts at €6,000. A full product with payments, user accounts and an admin panel runs €12,000-€25,000. Complex products with real-time features or marketplace logic start from €30,000. Prices are fixed per scope, not hourly. Białystok does not have a dense local mobile agency market, so most businesses work with remote developers.
How long does it take to build a mobile app? A real MVP - deployed to App Store and Google Play - takes 4 to 8 weeks. First week: scoping and screen design. Then three to five weeks of building. Final week: QA and store submission. Google Play reviews in one to two days. Apple takes longer, and first submissions often come back with small policy issues - budget an extra week.
Should I build for iOS and Android separately? In most cases, no. React Native produces both platforms from one codebase at 30-60% less than two native builds. Build native separately only when the app genuinely requires platform-specific hardware access at a level React Native cannot reach - games, heavy AR, or specialized sensor work.
Can I work with you remotely from Białystok? Yes - that is how all projects run. Scoping call online, fixed quote in writing, weekly updates via email or short call. No physical meeting at any stage.
Do you handle App Store and Google Play submission? Yes, it is included. I prepare all store assets, manage the review process, and handle rejections. Apps are always published under your developer accounts.
What do I need to have ready before the project starts? A business description of what the app should do - not a technical spec. Brand assets: logo and colors. Access credentials for systems the app integrates with. Content for the app screens. Missing content is the most common cause of project delays.
