Whatever the scope, the following are delivered as standard — no extra cost.
Bring these — we produce the right quote in 60 minutes.
Native (Swift + Kotlin): highest performance + access to Apple/Google's newest 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. Recommended for: MVPs, e-commerce, B2B, content apps. We recommend per your scenario in the discovery call; we won't push native if it isn't needed.
Google Play: 2-8 hours after submission (usually live same day). Apple App Store: 1-3 business days after submission. Account setup included: Apple Developer Program (€99/yr) and Google Play Console (€25 one-time). Accounts opened under a Spanish entity with Spanish IBAN in your name, ownership 100% yours. Free revision if rejected.
Full compliance out of the box. RGPD/AEPD: granular consent, Records of Processing Activities, signed DPA, ARSULIPO rights flows. LSSI-CE: compliant cookie banner, legal notice and privacy policy. ATT (iOS): App Tracking Transparency prompt configured. SII and Verifactu: real-time AEAT reporting, software compliant with RD 1007/2023 from July 2026. TicketBAI: supported for Basque Country clients. Hosting on AWS Madrid (eu-south-2) or IONOS Madrid — data never leaves the EEA.
Yes, all the relevant Spanish rails out of the box: Stripe ES (Spanish account with SEPA), Bizum (Pay by Bizum for e-commerce and P2P), Redsys (virtual POS for most banks), Adyen, PayPal, Apple Pay, Google Pay, BBVA and Santander virtual POS. Settlement to a Spanish IBAN, SEPA reconciliation with your ERP (Holded, Sage 50, A3, SAP Business One).
Nothing material. 23 of our last 24 apps were approved on first submission. We know Apple's 4.0 (Design), 5.1 (Privacy), 2.5 (Performance) guidelines by heart. If rejected: free revision (if it's our code) or add-on module quote (if content policy violation). Guaranteed.
Code is 100% yours. GitHub repo is transferred for free. You can switch to another mobile app developer in Madrid, Barcelona or Valencia, or hire your own in-house dev. App Store and Google Play accounts are also in your name under a Spanish entity — ownership 100% yours. Vendor lock-in is not our model.
Every project gets a senior mobile developer (min. 5 years iOS/Android experience). Our 12-year team includes developers who have worked at Glovo, Cabify, BBVA, Telefónica and BBVA Next Technologies. Juniors work under code review — the senior owns output. We introduce the assigned developer during the discovery call.
Three options: (1) Shared backend — web + mobile feed from a single API, cart from web shows up on mobile. Most common. (2) WebView hybrid — if budget is tight, parts of the app render a web page (Apple discourages this, must be done carefully). (3) Fresh mobile — mobile-specific UX, synced with web via API. We recommend per your scenario in the discovery call.
Spain holds one of Europe's highest smartphone penetration rates (above 93%) and screen-time exceeding four hours a day — well above EU averages. Publishing on App Store ES and Google Play España is not a technical checklist alone; it requires a market-specific configuration on payments, identity and privacy. This playbook walks through Apple Pay España integration, the Bizum native flow, Open Banking PSD2 in Spain and App Store ES localisation.
The Apple App Store ES storefront is a separate store, not merely a language layer — screenshots, description, keywords and category ranking are independent. Castellano is the default; if your Catalan user base is significant you should add a catalán (ca-ES) screenshot set. In App Store Connect, add both "Spanish (Spain)" and "Catalan" localisations; Google Play uses the same es-ES + ca tags.
ASO keyword choice must reflect Spanish search behaviour — use "compra", "ofertas", "comprar online" (Castellano forms), not the LatAm variants. Category choice: e-commerce apps go under "Shopping"; restaurant apps benefit from cross-listing "Food & Drink" + "Lifestyle".
Apple Pay launched in Spain in 2016 with BBVA and now covers 20+ banks including Santander, CaixaBank, Sabadell, ING España and Revolut. Adding Apple Pay to a mobile checkout typically lifts conversion 22% vs manual card entry (ZunaPro Spain cohort average). Setup involves an Apple Developer Merchant ID, the Apple Pay Payment Processing Certificate and token integration with Redsys, Stripe or Adyen.
Bizum is inherently mobile-native — and your app is where the real difference shows. The native iOS and Android SDKs sit on Redsys-Bizum infrastructure. The flow: the shopper selects Bizum, enters their phone number (or the device detects it), receives a push notification in their bank app, confirms with Face ID or Touch ID, and is returned to your app. End-to-end 8-12 seconds.
ZunaPro's mobile SDK integrates Bizum in a single configuration line; React Native, Flutter and native iOS/Android wrappers all ship. Placing Bizum alongside Apple/Google Pay completes the Spanish payment preference hierarchy: 42% Bizum, 28% Apple Pay, 18% manual card, 12% PayPal/other (2025 average).
PSD2 in Spain is supervised by Banco de España; AISP (Account Information Service Provider) and PISP (Payment Initiation Service Provider) licences are open to applicants. Fintech apps or advanced e-commerce platforms can read user balances at BBVA, Santander or CaixaBank, or initiate direct payments — all behind PSD2 SCA. ZunaPro's Open Banking module integrates with Tink, TrueLayer and Spain-native Afterbanks aggregators.
AEPD enforces mobile consent rules more strictly than web. iOS App Tracking Transparency (ATT) is mandatory; Android Google Play Data Safety must be filled in app metadata. ZunaPro's consent SDK supports Google Privacy Sandbox, IAB TCF v2.2 and the AEPD 2023 spec in parallel, with a separate COPPA + RGPD-K flow for under-16 minors.
Spanish users accept push notifications at higher rates than the EU average (68% vs 58%) — but uninstall rates spike fast on abuse. The 14:00-16:30 siesta window and the 22:00+ "no molestar" default are cultural realities; sending push during these windows is a negative signal. ZunaPro's notification module enforces quiet hours by device timezone automatically.
App Store ES review averages 24-48 hours. Common rejection causes: (1) using the Bizum mark without Redsys licence, (2) missing NIF/CIF in App Privacy disclosure, (3) promising catalán localisation in description without shipping it (LCC violation), (4) marketing copy like "compra rápida y segura" presented as a guarantee.
Reaching Spanish TestFlight beta cohorts is straightforward — Madrid, Barcelona and Valencia all host active tech communities. Performance targets during beta: cold start under 2 s, app size under 80 MB, Crashlytics crash-free above 99.5%. That is the performance bar Inditex's Zara Iberia app and Mercadona's app set across the mainstream. ZunaPro's performance dashboard tracks these KPIs continuously.
