Mobile app development company built in Poland, shipped worldwide.

A mobile app development company covers the full lifecycle of a mobile product: discovery, UX and UI design, native or cross-platform engineering, backend and API work, QA on real devices, App Store and Google Play submission, plus post-launch monitoring and iteration. EonTech acts as a full-cycle mobile app development services company, so a single senior team owns each of those stages instead of stitching together freelancers or single-purpose vendors.

A custom mobile app development company designs the product around your users, data model, integrations and monetisation — not around a rigid template. You choose the tech stack, own the code and can extend it in any direction. Template shops move fast on very generic use cases but tend to hit walls the first time you need a real integration, a custom UX flow or a compliance requirement.

Yes. As an experienced mobile app development company we ship products for fintech, healthtech, logistics and enterprise SaaS. Regulated engagements start with a data-processing agreement, an agreed threat model and — where relevant — mapping against GDPR, PSD2/PSD3, HIPAA or ISO 27001-aligned controls. Compliance is scoped in during discovery, not bolted on before launch.

On demand mobile app development company work is one of our most common project shapes. We build rider/driver, customer/provider, marketplace and delivery apps with real-time dispatching, geolocation, payments, ratings and admin dashboards. Backend, mobile clients and DevOps come from the same team, which is what keeps latency, uptime and unit economics in a healthy place.

Most mobile app development company services engagements start with a paid 1–2 week discovery: goals, users, competitive scan, scope, architecture and estimate. From there we move into design and build in weekly slices. Fixed-scope MVPs, time-and-materials feature squads and dedicated teams are all supported — you pick the model that matches your stage.

A mobile app software development company like EonTech is a good fit when you need velocity without permanent headcount, when you are missing a specific skill (iOS, ML, DevOps) or when you want an outside partner to de-risk a launch. Many clients start with a fully outsourced build and then gradually pull the team in-house — because you own the code and pipelines, that transition is a hiring exercise, not a re-platform.

As a mobile app development service company we default to Swift/SwiftUI for iOS, Kotlin/Jetpack Compose for Android, and React Native, Flutter or Kotlin Multiplatform where cross-platform makes sense. Backends run on Node.js, Python or Go on AWS, GCP or Azure. AI features use Core ML, TensorFlow Lite, ONNX and hosted LLM APIs depending on latency and privacy constraints.

Selected work lives on our mobile app development company website under /work/. Some engagements are covered by NDA, so if you want references or deeper technical write-ups for a specific industry — fintech, healthtech, logistics, marketplaces — request them during the introductory call and we will share them under a mutual NDA.

A production-grade MVP with iOS, Android, a backend and an admin panel typically runs in the low six figures EUR and 3–5 months of build time. A more ambitious product with custom AI, deep integrations and enterprise compliance sits above that. We share a written estimate at the end of discovery so you can compare apples to apples across vendors.

Email [email protected] or use the contact form. A short intro call is enough to gauge fit. If we agree there is a match, we scope a paid discovery, propose a team shape and share a fixed timeline. You are never asked to commit to a full build before the plan is on paper.
