Mobile app services
Tailored mobile app development for businesses in Jász-Nagykun-Szolnok County — no templates, always custom.
React Native / Flutter Cross-Platform App
iOS and Android app from a single codebase — half the development time, half the cost, same quality. Native UI components, 60fps animations.
Push Notifications & Messaging
Firebase Cloud Messaging and APNs integration. Segmented, scheduled, personalized notifications — direct connection with the user.
Backend & API Development
Your own REST/GraphQL API, or connect to existing systems. Supabase, Firebase, custom server — experienced with all.
Offline Mode & Local Database
Local database (SQLite, Realm, WatermelonDB), data cache, background sync. The app works without internet.
In-App Purchase & Payment Integration
Apple In-App Purchase, Google Play Billing, Stripe, SimplePay integration. Subscriptions, one-time payments, paid content.
App Store & Google Play Publishing
Full publishing process: account setup, app submission, review, screenshots, metadata, release management.
Long-term it's much more worth it
A custom mobile app is not a luxury — it's an investment. A web solution doesn't replace the native app experience: push notifications, offline mode, biometric auth, App Store presence — these are things only a native app can do. And custom development means the code is yours.
- One codebase, two platforms

What can a custom mobile app do
that the web can't?
A native mobile app isn't just the mobile version of a website. Capabilities that only an app can deliver — and that mean real business advantage.
One codebase, two platforms
React Native or Flutter — iOS and Android app from a single codebase. Half the development cost, identical quality.
Native performance
60fps animations, instant launch, native UI components. The user can't tell the difference between a native Swift/Kotlin app and the cross-platform solution.
Push notifications — direct channel
Firebase Cloud Messaging (Android) and APNs (iOS) integration. Straight to the user's pocket — 90% open rate within 24 hours. No web solution comes close.
Offline mode
Local database (SQLite, Realm, WatermelonDB) — the app works without internet. Data cache, background sync, offline mode built in. The user never waits.
Biometric authentication
Face ID, Touch ID, fingerprint built in. No password — the user logs in with a glance. Secure, fast, modern — exactly what big apps offer.
App Store presence
Full publishing process: App Store and Google Play upload, description, screenshots, ASO optimization. Being in the app store is itself marketing and trust.
OTA updates
Over-the-air updates — fixes are instantly available, no need to wait for App Store review for every small change (React Native CodePush, Flutter Shorebird).
Device integration
Camera, GPS, accelerometer, Bluetooth, NFC — every device capability available. Features impossible or limited on the web.
Web vs. Mobile App — why neither replaces the other
The website is the first encounter — from search, a link, an ad. But for return visits, regular use, loyalty — you need an app. Whoever downloads the app is already committed. And push notifications do what neither email nor SMS can: instantly, on the screen, with 90% open rate.
