Frequently Asked Questions

Should I choose native or React Native / Flutter?

Native (Swift + Kotlin): Highest performance + access to new Apple/Google features (Live Activity, App Clips, Material You). Recommended for games, AR, video editor, projects with 1M+ users. Cross-platform (React Native / Flutter): 50% cheaper + single codebase + 2x faster development. Recommended for MVP, e-commerce, B2B, content apps. At discovery we recommend based on your scenario; we will not push native if it is not needed.

How long for App Store + Google Play publishing?

Google Play: 2-8 hours after submission (usually live the same day). Apple App Store: 1-3 business days after submission (Apple App Review). Account setup included: Apple Developer ($99/year) and Google Play Console ($25 one-time) with Greek tax ID + IBAN. Ownership 100% yours. Free revision if rejected.

Do you handle Apple/Google VAT on app fees?

Apple and Google automatically withhold Greek 24% VAT on in-app purchases — you do not need to declare it for in-app payments. For external payments (Viva Wallet / IRIS direct), we integrate a webhook to myDATA AADE for real-time invoicing. Consult your accountant — Greek digital services have specific requirements (MOSS/OSS reporting for cross-border EU digital deliveries).

Do you hand over the code or do we stay dependent?

Code is 100% yours. GitHub repository handed over for free. You can continue with another mobile app development company, hire in-house developers. App Store + Google Play accounts in your name with Greek tax ID — ownership 100% yours. Vendor lock-in is not our model.

Who will build the app — junior or senior?

Each project gets a senior mobile app developer (min. 5 years iOS/Android). Our 12-year team includes developers who worked at Skroutz, Viva Wallet, efood. Juniors work under code review — the senior is accountable for output. At discovery we introduce the developer assigned to your project.

Do iOS + Android look identical if built separately?

Ideally no. Apple Human Interface Guidelines and Material Design are different design languages. iOS users expect SF Pro font + navigation transitions; Android users expect Roboto + bottom sheet + ripple effect. Native = each platform compliant with its standards (user satisfaction +30%). Cross-platform (React Native/Flutter) = one design across both, pragmatic choice.

Are push notifications, payments, analytics included?

Part of the standard package: OneSignal/Firebase push, Viva Wallet/IRIS/Stripe/Alpha Bank ePOS payments + Apple Pay + Google Pay + PayPal, Firebase Analytics + Mixpanel, Sentry crash, biometric login. Extra integrations (Zendesk, Intercom, Branch.io deep linking, MapKit/Google Maps, ARKit/ARCore, Box Now lockers) included in scope — no extra charge.

I have a website, how does it integrate with the app?

Three options: (1) Shared backend — web + mobile fed from one API, user sees their cart on mobile too. Most common method. (2) Hybrid with WebView — if budget is low, parts of the app show web (Apple does not love it, requires care). (3) Entirely new mobile — mobile-first UX, syncs with web via API. At discovery we recommend per your scenario.

Greek Mobile App Development — Viva Wallet, Apple Pay, IRIS Payments and αντικαταβολή

Smartphone penetration in Greece is 88% and 48% of e-commerce sessions originate on mobile-first devices. For a Greek brand a mobile app is no longer "nice to have" — it is a critical investment. But Greek consumer payment behaviour diverges from the global average in two notable ways: αντικαταβολή (cash-on-delivery) still commands 25–30% share and bank-rail IRIS Payments is rising fast. This guide explains how to build a Greek iOS/Android app on top of Viva Wallet in-app SDK, Apple Pay GR, IRIS rail integration, an αντικαταβολή flow and HDPA-compliant consent.

Greek mobile landscape — the numbers

  • 10.4M active smartphone users out of 11M residents (94%)
  • iOS 42% / Android 58% — iOS above EU average (higher income + diaspora)
  • 5G coverage 99% in Athens / Thessaloniki, 80% national
  • Mobile add-to-cart 53%; mobile checkout completion 38% (web 52%)
  • Push notification opt-in 42% (Türkiye 58%)

Viva Wallet in-app SDK — the local checkout superpower

Viva Wallet's official iOS and Android in-app SDK embeds Apple Pay, Google Pay, card-on-file, IRIS instant SEPA and BNPL into a single native flow. ZunaPro bridges Viva Wallet into React Native and Flutter projects as well. Note: Smart Checkout mode offloads PCI scope entirely to Viva Wallet, so your app handles only tokenised references.

Apple Pay GR — Merchant ID, certificates and in-app flow

Apple Pay has been active in Greece since 2021 and is supported by Alpha Bank, Eurobank, Piraeus, National Bank, Viva Wallet and Stripe. ZunaPro binds your Apple Developer account to a Merchant ID, provisions the Payment Processing Certificate and codes the Apple Pay button + paymentRequest pipeline. iOS 17's Tap-to-Pay on iPhone eliminates the need for a separate POS terminal for field-sales teams (supported in Greece on Viva Wallet and Stripe).

IRIS Payments mobile rail — instant SEPA push

IRIS Payments, operated by DIAS Interbank, is the Greek instant-SEPA rail. From within the app the user scans a QR code or enters an AFM and pays in one tap. ZunaPro embeds the IRIS pay button, deep link (irispayments://...) and callback handler; settlement confirmation returns to the app within seconds.

Αντικαταβολή mobile flow — cash-on-delivery remains Greek

When αντικαταβολή is selected in-app, the ZunaPro pipeline runs the following steps: (1) a €1.50–€3.00 cash-handling surcharge is auto-added to the cart, (2) on order confirmation the ACS Courier API is called to print a COD-flagged label, (3) a push notification informs the user about courier arrival, (4) once collected, the invoice is transmitted to myDATA AADE and (5) bank reconciliation appears in the app at T+2.

App Store el-GR localisation — avoid Greeklish

Your App Store / Play Store listing must use full Greek-alphabet title, description, screenshots and release notes. Greeklish (e.g. "kalimera, kane download") gets demoted by App Store SEO algorithms. The ZunaPro localisation package ships el-GR + en-GR fallback plus diaspora locales de-DE, en-AU, en-US.

HDPA & GDPR mobile compliance

  • First-run explicit consent screen (analytics / marketing / measurement categories)
  • iOS App Tracking Transparency (ATT) + Greek-language dialog
  • Data controller details visible in Settings (AFM, address, DPO email)
  • One-tap "Delete account" + "Export my data" (30-day SLA)
  • Field-level encryption + biometric lock in health/finance apps

ZunaPro Greek mobile app package

  • iOS + Android native or React Native / Flutter
  • Viva Wallet in-app SDK + Apple Pay + Google Pay
  • IRIS Payments deep-link integration
  • αντικαταβολή flow + ACS Courier API + push notifications
  • myDATA AADE connector + QR-coded PDF
  • App Store + Play Store el-GR localisation + ASO
  • HDPA-compliant consent + data access portal

Push notifications — the right rhythm for Greek users

Push opt-in in Greece runs 42% — below Türkiye's 58% but above the EU average. 19:00–21:30 evenings deliver the highest click-through; 07:00–09:00 mornings the lowest. ZunaPro integrates OneSignal, Firebase Cloud Messaging or the local Notificare option and manages segment + timezone + language + first-name personalisation.

ASO el-GR — App Store SEO in Greek

App Store / Play Store discovery in Greek reads the title, subtitle, keywords (Apple), long description (Google) and screenshot copy. The ZunaPro ASO team picks ranking keywords from a 250+ keyword pool in Greek and reports monthly on CR, impression-to-install and organic traffic.

In-app subscriptions — Greek price sensitivity

Greek iOS/Android users convert to premium subscriptions at 4.2% (EU average 6.8%, Türkiye 2.1%). The highest-converting offer is €2.99/mo starter tier, €19.99/year annual plan, 7-day free trial. ZunaPro integrates StoreKit 2 (iOS) and Google Play Billing Library 6 (Android), with RevenueCat handling cross-platform subscriber state.

Crash and performance monitoring — Crashlytics + Sentry

Greek island connectivity produces network-bound crashes (offline-first design is essential). ZunaPro stacks Firebase Crashlytics + Sentry Performance + GDPR-compliant (Frankfurt-hosted) Mixpanel or Amplitude. Crash-free user target ≥99.5%; Android ANR target ≤0.5%.

Offline-first design — usable on island connectivity

Aegean island 4G coverage is intermittent — your app must use local SQLite cache, optimistic UI updates, a network-status banner and a conflict-resolution queue. ZunaPro's mobile builds standardise on WatermelonDB (RN), Drift (Flutter), Core Data (iOS) or Room (Android) for a local-first architecture.

Deep links + universal links — campaigns into the app

Driving users from SMS, email or Instagram ads into the app uses Apple Universal Links + Android App Links. The ZunaPro deep-link scheme routes zunapro.gr/product/12345 straight to the product page or to the App/Play Store install screen if the app is missing.

Live activities + Dynamic Island — innovative UX

iOS 16+ Live Activities and iOS 17 Dynamic Island are ideal for order tracking, courier location and appointment countdowns. The ZunaPro mobile package includes ActivityKit (iOS) and Notification Live Updates (Android 14+) implementations.

A/B testing and feature flags — continuous optimisation

ZunaPro mobile apps ship with Firebase Remote Config + Statsig or GrowthBook for feature flags and experiments. You can A/B test Greek price sensitivity, checkout step count, COD vs Viva Wallet preference. Flags flip on p<0.05 significance and roll back otherwise.
