Services · App Development

App development that scales.

Native iOS and Android apps, cross-platform with Kotlin Multiplatform, React Native or Flutter – with a scalable cloud backend. We build apps that carry the business, not just the surface.

App development – mobile products by apprime

A decision we explain.

Native or cross-platform – the answer depends on product, team and operating scenario. We recommend what fits. Not what's trending.

01

Native iOS

Swift & SwiftUI for apps with deep system integration, performance and App Store quality. We have been building iOS since 2011.

02

Native Android

Kotlin & Jetpack Compose for Android-first strategies, device diversity and B2B deployments via MDM.

03

Cross-Platform

Kotlin Multiplatform, React Native, Flutter – for products with high feature velocity and a shared team.

04

Mobile backend

Cloud infrastructure, APIs, auth, push, billing. Without a solid backend, no app will scale.

What we use.

A curated stack, not a tool cloud. We rely on established technologies with a long runtime – and decide per project what really fits.

From first call to release.

Four phases, one team. Strategy, execution and operations stay in one hand — no handoff where knowledge gets lost.

01

Discovery & architecture

We clarify product goals, user groups, platform strategy and data model. Outcome: a binding architectural decision and a scope that can actually ship.

02

MVP in 3–6 months

We build the product iteratively – with running builds starting week 4. TestFlight and Play internal track deployments, backend live, telemetry from day one.

03

Release & scale

Store submission, monitoring, crash reporting, performance budget. Feature releases on a two-week cadence, backend scaling based on actual usage.

04

Ongoing operation

We run, maintain and extend. Many of our apps have been running stable for 5+ years – with the same team and clear ownership.

Frequently asked.

What does app development cost at apprime? +

It strongly depends on the type of project. An MVP or pilot project typically starts at around €20,000 to quickly validate an idea in the market. Serious production-grade solutions with scalable architecture usually begin at €40,000. More complex platforms with multiple user roles, backend systems, and integrations go beyond that. The key cost driver is rarely the platform itself, but the architecture: a clean data model and a solid backend structure prevent expensive follow-up costs. After a short conversation, you’ll receive a reliable estimate within 24 hours.

Native apps or cross-platform (Flutter, React Native, Kotlin Multiplatform)? +

The decision depends on product, team and operational scenario — not on framework fashion. For apps with deep system integration or specific performance demands, we recommend native development. For products with high feature velocity and limited team resources, Kotlin Multiplatform or React Native is often the better choice. We decide architecturally, not dogmatically.

Do you take over existing apps, or only new builds? +

Both. We have taken over apps that were started by other teams — stabilized them, extended them, or fully modernized them. The first step is always a technical audit: code quality, architecture, backend dependencies, store status.

How long does an app project take? +

This depends on the project—and heavily on client-side involvement (decision-making, content delivery, feedback cycles). A solid MVP is typically ready in the store within 3 to 5 months. More complex platforms with backend, admin panel, and multiple user roles usually take 5 months or more to reach production readiness. We work iteratively, with functional builds available from week 4, so you can test early and actively steer development.

Do you operate the app after release? +

Yes. We run backends, monitoring, release pipelines and store submissions — and evolve the app continuously. Many of our projects have been in production for years.
