Mobile apps in Warsawthat actually ship to stores.

The number of screens, integrations, backend and design. A simple project / MVP usually starts in the low tens of thousands of zloty; a larger app costs more. I quote fixed price — we agree the scope and cost up front, no surprises on the invoice.

A short brief is enough: what the app is for, which features are key, and who'll use it. From there we go in stages: analysis and quote → mockups → development in sprints → testing → release → maintenance. You see progress as we go.

Typically 4–6 weeks from kickoff to TestFlight / Internal Testing. Another 1–2 weeks to the public stores (depends on Apple review).

I build one cross-platform app (Expo / React Native) that runs on iOS and Android from a single codebase — you don't pay twice. The same code can later add a web version too. On a tight budget you can launch one platform first and add the second later.

For 90% of product tasks — no. Expo / React Native gives native perf and full hardware access. Native code makes sense for AR, heavy graphics or specialized hardware. I'll tell you straight.

No-code works for a very simple idea, but it hits a wall fast: performance, integrations, ownership and the builder's monthly subscription. A custom app has none of those limits, belongs entirely to you, and scales with the business.

I do — review responses included. Apple Developer and Google Play accounts are set up under your company, and I work under your details. An Apple rejection is standard, not cause for panic — I know what they usually nitpick; we fix and resubmit at no extra charge.

You do — fully. The source code, App Store Connect and Google Play accounts, backend and all keys are set up under your company and transferred to you by contract. I don't hold the project hostage or lock you in: you can keep building it yourself or hand it to any other developer.

Less than the software houses make you fear. Backend hosting and services are typically €10–50/month depending on traffic; the store accounts are $99/year for Apple and a one-time $25 for Google. Fixes and updates for new iOS/Android versions are €50/hour with no mandatory retainer — you only pay when something actually needs doing.

We work across all of Poland and remotely — Warsaw, Kraków, Wrocław, Gdańsk, Poznań or a smaller town, it makes no difference. Calls, demos and handover happen online; the contract and payment are remote. An in-person meeting in Warsaw is available on request.

Publishing is half the job; then ASO kicks in: a name and subtitle matched to store searches, keywords, and screenshots that sell rather than just show screens. I do baseline ASO at publishing. An app also almost always needs a landing page - the page Google finds, with the Download button. I build those too; see the Body Forge landing in my work.

Yes, and it's cheaper than it sounds. Body Forge ships an AI coach on GPT: it reads your workout and returns a personal analysis in ~10 seconds. The same pattern adds an AI consultant, copy generator, photo analysis or voice input to your app. Usually that's +€900 on the quote, not a separate project.

The cross-platform stack updates in step with iOS and Android, and small fixes fall under €50/hour support - usually 1-2 hours a year. The Apple developer account costs $99/year, Google's is a one-off $25, both registered to you. No mandatory “keep it alive” retainers.

It's enough. You don't need a classic spec: on a call we strip the idea down to the core flow - who the user is and which action makes money. From that I produce a screen map and a quote; you approve. It's free and commits you to nothing: worst case, you leave with your idea neatly structured.
