Mobile App Development

Mobile Apps, Shipped to the Stores

VZT Tech Consulting builds mobile apps end to end — native iOS, native Android, and cross-platform React Native — and handles the full launch through App Store Connect and Google Play Console. We've published apps live on both stores, including NextPlay Highlights.

Cross-Platform (React Native)

One codebase, both stores. We build React Native (Expo) apps that ship to iOS and Android together — the fastest, most cost-effective path for most products without sacrificing native feel.

  • iOS + Android from one codebase
  • Expo / React Native
  • Native modules when needed
  • Faster, lower-cost builds

Native iOS & Android

When a product needs deep platform features or maximum performance, we build native — Swift for iOS, Kotlin for Android — with platform-correct UX and full hardware/API access.

  • Swift (iOS) & Kotlin (Android)
  • Deep platform features
  • Push notifications
  • In-app purchases

App Store & Google Play Launch

We handle the part that trips most teams up: App Store Connect submission, Google Play Console publishing, TestFlight betas, store listing optimization (ASO), and getting through review.

  • App Store Connect submission
  • Google Play publishing
  • TestFlight betas
  • Store listing / ASO

Backends & Post-Launch

Apps need a backend — auth, APIs, real-time sync, payments, and analytics — plus updates after launch. We build the whole system and support it once it's live.

  • APIs & real-time sync
  • Auth & secure storage
  • RevenueCat / IAP
  • Updates & support

Frequently Asked Questions

Do you build native or cross-platform apps?

Both. We build cross-platform React Native (Expo) apps when you want one codebase shipping to iOS and Android together, and fully native Swift/Kotlin when a product needs deep platform features or maximum performance. We'll recommend the right fit for your goals and budget.

Do you publish the app to the App Store and Google Play?

Yes — end to end. We handle App Store Connect submission, Google Play Console publishing, TestFlight betas, store listing optimization, and getting through review. NextPlay Highlights, which we built, is live on both stores.

Can the app have payments or subscriptions?

Yes. We implement in-app purchases and subscriptions (via RevenueCat / StoreKit / Google Play Billing) and integrate Stripe where appropriate, following each store's payment rules to avoid rejection.

Do you support the app after launch?

Yes. We provide post-launch updates, OS-version maintenance, new features, and store-compliance updates so your app keeps running as iOS and Android evolve.
