Whatever the scope, the following ship as standard — no extra cost.
Bring these — we deliver the right quote in 60 minutes.
Native (Swift + Kotlin): Highest performance + access to newest Apple/Google features (Live Activity, App Clips, Material You). Recommended for: games, AR, video editors, projects with 1M+ users. Cross-platform (React Native / Flutter): 50% cheaper + single codebase + 2x faster delivery. Recommended for: MVPs, e-commerce, B2B, content apps. We advise based on your scenario in the discovery call; we won't push native if you don't need it.
Yes. BLIK (Mobile Authorization in-app), Przelewy24, PayU, Tpay, Stripe PL, Apple Pay and Google Pay integration are all standard. The payment-provider contract is signed under your NIP (BLIK requires an agreement with Polski Standard Płatności or via Przelewy24). We help with KYC and first-time setup.
Yes. RODO privacy policy, consent forms, right to be forgotten, EU data residency (OVH PL or AWS Frankfurt). Invoices generated by the backend can be pushed to KSeF (Krajowy System e-Faktur — mandatory 2026). NIP/REGON checked online against the GUS Biała Lista. Compliant with the Polish national cyber-security act.
Google Play: 2-8 hours after submission (usually live same day). Apple App Store: 1-3 business days (Apple App Review). Account setup included: Apple Developer Program ($99/year) and Google Play Console ($25 one-time). Account is opened under your Polish entity with a Polish IBAN for payouts — 100% ownership yours.
Code is 100% yours. GitHub repo handed over free. You can take it to another mobile developer or hire an in-house team. App Store and Google Play accounts are in your name — ownership 100% yours. Vendor lock-in is not our model.
A senior (min. 5 years iOS/Android) leads every project. Our 12-year-old team includes developers who have worked at Allegro, mBank, Pyszne.pl and similar large companies. Juniors work under code review — the senior is accountable. We introduce the assigned developer in the discovery call.
Standard package: OneSignal/Firebase push, BLIK/Przelewy24/PayU/Tpay/Stripe + Apple Pay + Google Pay, Firebase Analytics + Mixpanel, Sentry crash, biometrics (Face ID/Touch ID/Android Biometric). Extra integrations (mObywatel, Zendesk, Intercom, Branch.io deep linking, MapKit/Google Maps, ARKit/ARCore, InPost Paczkomaty) included in scope — no extra fee.
Three options: (1) Shared backend — web + mobile from one API, the cart you added on web shows up in mobile. Most common. (2) Web view hybrid — on a tight budget, part of mobile renders web pages (Apple dislikes this, must be careful). (3) Fresh mobile — mobile-first UX, synced with web via API. We recommend based on your scenario in the discovery call.
The defining feature of Poland's mobile payment ecosystem is BLIK. Polish users open their banking app and generate a six-digit code instead of tapping a card. A mobile app without BLIK is treated as half-built. Beyond BLIK, Apple Pay PL, Google Pay PL, mObywatel (the national digital ID), Allegro and InPost Mobile are pillars of Polish mobile UX.
BLIK is a domestic bank-rail payment scheme operated by Polski Standard Płatności (PSP) with 14 million active users. Two paths to integrate BLIK into your app: direct PSP partnership + bank wiring (large brands), or accepting BLIK via the Przelewy24/PayU SDKs (pragmatic for SMBs and startups).
Apple Pay has worked in Poland since 2018 with mBank, ING, Santander and Pekao. Google Pay's bank coverage is broader. Combined they account for 20-25% of mobile checkout volume; offering them alongside BLIK is non-negotiable.
mObywatel is the Polish government's official mobile identity app, carrying driver's licence, national ID (mDowód), prescriptions and vehicle registration. Third-party apps can call the "Sprawdź wiek" (age verification) and eDoręczenia (formal delivery) APIs to authenticate users. Essential for regulated verticals — adult, gambling, alcohol, insurance.
Poland's two effective mobile super-apps are Allegro and InPost Mobile. Your app can pull orders via Allegro Open Platform (REST/OAuth) and embed the Paczkomaty picker via the InPost Mobile API. Without these integrations Polish users will not treat your app as native.
To rank in the PL App Store and Play Store: PLN pricing, Polish copy with preserved diacritics, a UODO-compliant privacy policy, KSeF e-invoice emission (for B2B in-app subscriptions), and Polish PTU/VAT remittance.
Location, photo, contacts and microphone permissions in a Polish mobile app require RODO granular consent and opt-out. Data breaches must be notified to UODO within 72 hours. The ZunaPro mobile SDK ships a TCF v2.2-compliant consent management platform.
