Mobile apps people want to open.

From kickoff to the stores. Native iOS and Android, or cross-platform Flutter and React Native when it makes sense. Real performance, serious accessibility, an experience that sticks with the user.

Native where it counts. Cross-platform when it makes sense.

There's no universal answer between native and cross-platform. There's the right answer for your product. Native (Swift on iOS, Kotlin on Android) for max performance, advanced sensor integration, premium App Store experience.

Flutter and React Native for smaller teams, tight time-to-market, or when 90% of features are shared UI. We decide together after understanding numbers, target, roadmap. No ideologies.

High-stakes finance apps — Trading, banking, fintech: Swift and Kotlin for minimum latency, native Face ID, hardware-backed security.
MVP with a lean team — Flutter or React Native: one codebase, two stores, half the sprints. Quick pivots without rewriting.
Niche apps with hardware — Native Bluetooth, ARKit, NFC, car-play / wear-os integrations. Cross where possible, native bridges where needed.

Crash-free sessions

Fast from the first tap. Always.

Cold start under a second. 60fps scrolling even on 4-year-old devices. Animations that mean something. Skeleton screens instead of spinners. No jank, no loads that make people close the app.

Accessibility isn't a checkbox at the end: VoiceOver, TalkBack, AA/AAA contrast, dynamic type, real dark mode. More people use your app — better numbers.

Cold start budgetTarget < 1s. Bundle size, lazy load, smart splash. Crash-free rate > 99.5%.
Accessibility-first — Screen readers tested on real users. 44pt hit targets. WCAG 2.2 AA certified contrast.
Offline gracefully — Local persistence, conflict-free sync, clear indicators when offline. Never blank screens.

An app is the tip of an iceberg.

Beneath every app there's a backend doing the heavy work: APIs, sync, push notifications, auth, storage, analytics. We build the backend with the app (or integrate with yours), with an architecture that scales with your users.

Offline-first where it matters: the user keeps working without signal, sync resolves conflicts when back online. Push notifications that arrive, deep links that work, OTA updates for urgent fixes without going through the store.

Offline-first sync — CRDT or event-sourcing architecture. Users work on the subway without noticing.
Push that converts — Segmentation, A/B test, deep links to specific screens, retry queue, transparent opt-in.
Enterprise auth + SSO — Apple/Google Sign-in, MFA, biometrics, SAML/OAuth SSO, transparent session refresh.

Approved on first try.

We know Apple and Google's guidelines by heart. An App Store reject costs days — sometimes weeks. We handle metadata, screenshots, privacy nutrition labels, App Review, so the first submission goes through without ping-pong.

After launch: crash, performance and rating monitoring; weekly CI/CD releases; A/B tests on store listing; bad review management; OTA for critical fixes. Nobody disappears the day after go-live.

Pre-launch checklist — Privacy manifest, ATT, ITP, IDFA, App Tracking, AASA, Android intents: all sorted before submit.
Monetization — In-app purchases, subscriptions, optimized paywalls, RevenueCat and StoreKit 2 integration.
Localization — Languages, plurals, currencies, date/time formats, RTL. One pipeline for IT, EN, ES, FR, DE.

AI that runs in your pocket.

Models running locally on the device: vision, voice, NLP. Zero latency, max privacy, no per-query costs, works on a plane. CoreML on iOS, ML Kit on Android, ONNX Runtime cross-platform.

When you need power, hybrid: local features for instant answers, fallback to cloud LLMs for complex queries. The device does what it can, the cloud what it must.

Local OCR + NLP — Document scanning, text recognition, field extraction without sending anything off the phone.
On-device voice-to-text — Compressed Whisper on mobile, instant transcription even without signal.
User-side personalization — Models that learn user habits without data ever leaving the device. Privacy by architecture.
ON-DEVICE AI EXAMPLE

A good app brings people back.

People unlock their phone 80 times a day. Your app is one of dozens competing for those taps. We focus on what makes the difference: real speed, gesture-first design, accessibility for everyone.

No cosmetic decisions, every choice has measurable impact on retention, conversion, rating. When an app is done right, the user doesn't notice — it just works.

What we get asked the most.

Transparency first. If your question isn't here, write to us: we reply within 24h, from a real person.

Native or cross-platform — how do I decide?
Depends on features, budget, team. Small team or MVP? Cross-platform (Flutter/React Native) cuts time-to-market and halves maintenance. Specific hardware, critical performance, budget for two teams? Native wins. We decide together after a 2-3 day discovery.
How much does a mobile app cost?
Cross-platform MVP starts at €30–60k. Full native app with dedicated backend €80–250k. Finance/medical apps with compliance reach €300k+. Fixed quote after discovery, weekly sprints with demos.
How long to get to the store?
Cross-platform MVP: 8–12 weeks. Native app with custom backend: 16–24 weeks. Store review phase: 1–7 days Apple, 1–3 Google. We use feature flags for progressive rollout.
Can I integrate the app with existing systems?
Yes. CRM (Salesforce, HubSpot), ERP (SAP, Oracle), e-commerce, payment gateways, corporate SSOs. REST, GraphQL, gRPC, webhooks. Mobile is the access point, but your full infrastructure sits underneath.
How do you handle post-launch updates?
CI/CD pipeline with weekly or bi-weekly releases. OTA (over-the-air) for critical fixes via CodePush or Firebase Remote Config, so you don't wait for Apple review on a blocking bug. Continuous crash, performance and ratings monitoring.
What happens to the app after go-live?
We hand over code, docs, assets, store accounts. If you want maintenance/evolution we stay; otherwise we support you X months and you're autonomous. No vendor lock-in. All code is yours, all know-how transferable.
