Apps your users keep on the home screen — not in a folder called “maybe.”
iOS and Android, built together where it’s efficient and natively where it matters. Push notifications, offline, biometrics, payments — the real stuff, not just a WebView in a shell.

- React Native
- Expo

Most “mobile apps” are websites in disguise
The agency that quotes you €4k for a mobile app is building a webview that lags, can’t do push notifications reliably, and gets rejected by Apple twice before launch. Real apps need real engineering — and real engineering needs a team that’s actually shipped to both stores.

What you get
React Native + native where it counts
One codebase for 80% of the app. Native modules for camera, biometrics, BLE, background tasks. Best of both — not a holy war.
Offline-first, battery-smart
Local DB, sync queue, conflict resolution. Your app keeps working in an elevator, on a flight, in rural Slovakia. No spinner of death.
Push notifications done right
Deep links, scheduled pushes, rich media, in-app badges. Tied to your backend so you can segment, A/B, and measure.
Payments and subscriptions
Stripe, Apple IAP, Google Play billing. Proration, family sharing, promo codes, restore purchases. The weird edges — handled.
We actually ship to the stores
App Store and Play Store accounts, review responses, screenshots, privacy manifests, rejected-twice-recovered. Launch is a deliverable, not an afterthought.
Analytics + crash reporting
Sentry, PostHog, RevenueCat. You see what users do, where they quit, what crashes, and on which device — from day one.
What ships with every app
- React Native (Expo where it fits)
- Native modules (Swift / Kotlin)
- Auth (email, Apple, Google, Facebook)
- Offline storage + background sync
- Push notifications (OneSignal, Expo, FCM)
- Biometrics (Face ID, Touch ID, fingerprint)
- In-app purchases + subscriptions
- Deep linking + universal links
- Analytics + crash reporting
- Accessibility (VoiceOver, TalkBack)
- Localization (SK + EN + more)
- CI/CD with TestFlight + internal testing
App types we’ve built — and how we build each
Each vertical has its own “hard parts.” We’ve hit them.
Drivers, dispatchers, and customers — three apps, one system.
- Real-time GPS + route optimization

How we compare to the alternatives
Honest — including where we’re not the right choice.
| Criterion | AI SUCCESS | DIY / Freelancer | Big agency | Off-the-shelf SaaS |
|---|---|---|---|---|
| Launch time | 2–6 weeks | 3–6 months | 4–9 months | 1 day |
| Fits your workflow | 100% | 60% | 70% | 30% |
| You own the code | Yes | Maybe | Sometimes | No |
| Price transparency | Fixed quote | Hourly chaos | Retainer fog | Clear |
| Support when it breaks | 24h | When available | Ticket queue | Docs + email |
Common questions before you commit
Why React Native instead of fully native?
Because shipping to two stores with one team doubles your speed and halves your maintenance. For the 10% of cases where performance or platform APIs require native, we write native modules. You get the best of both.
How long does App Store review take?
Usually 24–72 hours per submission. We build to Apple’s and Google’s guidelines from day one, so rejections are rare. When they happen, we handle the response.
Who owns the app account?
You do. Your company registers the developer accounts (we’ll walk you through). We never publish apps from our account — that’s how agencies hold clients hostage.
What about updates after launch?
Monthly care plan or per-sprint basis. Over-the-air updates for non-native changes (no new store review). Full releases when you need them.
Do you do app icons, screenshots, and ASO?
Design yes; ASO copy usually with a partner. We handle the technical submission end-to-end.
Can you integrate with our backend?
Yes — and if your backend needs work to support mobile properly (auth, push, offline sync), we’ll flag it in the scope. No “it’ll just work” promises.
