Mobile

Native or cross-platform iOS and Android apps, designed for retention.

We design mobile applications that don't just work — they get used. From the lightweight PWA to the native React Native or Swift/Kotlin app, we aim for the fluid experience, offline-first CRUD, and green usage metrics (launch time < 2s, crash rate < 0.1%).

What we deliver

Concrete, measurable, no surprises.

  • React Native & Expo

    Shared iOS/Android code, fast iteration, OTA deployment for critical fixes without going through the store.

  • Native Swift / Kotlin

    When performance or low-level API access demands it — ARKit, Vision, HealthKit, sensors, BLE, background tasks.

  • Offline-first

    Local SQLite, conflict-prone sync, action queue — the app keeps working without network, and resynchronises elegantly.

  • Installable PWA

    For web-mobile use cases: installable, push notifications, file sharing, natural SEO hook.

  • Native mobile design

    Respect for the Human Interface Guidelines and Material Design. Gestures, haptics, transitions — not a web layer pasted on.

  • Observability & crash reporting

    Sentry, App Store Connect / Play Console metrics. Crash-free sessions ≥ 99.8%, cold start < 1.8s.

Non-negotiables

Our production standards.

Tools adapt to your context; our standards never move. Every project inherits this baseline — it is written into your contracts, not just this page.

  • One codebase, two platforms — controlled budget
  • App Store and Play Store release handled with you
  • Crash-free ≥ 99.8% required in production
  • Offline-first: the app stays useful without network
  • Code and store accounts transferred in your name
  • Fixes shipped without waiting on store review

Process

Four steps, one standard.

  1. 01

    Mobile discovery

    Use cases, target devices, whether offline mode is required, existing API integrations. Deliverable: specification and scoped budget.

  2. 02

    UX & prototype

    Wireframes, clickable prototype, real-world user testing (guerrilla). Lean first, rich later.

  3. 03

    Build & integrations

    2-week sprints, continuous TestFlight / Internal Testing builds, demos on physical devices.

  4. 04

    Store launch

    ASO listing preparation, submission, review handling, post-launch monitoring and a v1.1 plan.

FAQ

Frequently asked questions.

React Native or native?
80% of projects are covered by React Native — cost and iOS/Android consistency gains. We switch to native for 3D, BLE, or highly specific needs.
How much does an app cost?
A serious mobile app starts at €40k for an MVP, €80–150k for a full version. We answer within 48 hours with a precise range.
Do you publish on the App Store and Play Store?
Yes — full handling of the submission process, reviews, and compliance with Apple/Google guidelines.
What happens after launch?
Corrective and evolutionary maintenance, crash monitoring, OTA updates (RN), or native releases depending on the support contract.
Does my app work offline?
By default, yes for the use cases that need it: data reading, action queue, deferred sync.
Do you test on physical devices?
Yes, systematic testing on iPhone, low-end Android, iPad, tablets — not only on emulators.
