Mobile app development for iOS and Android.

Mobile app development done together: we design and build iOS, Android, cross-platform, and web-based (PWA) mobile products tailored to your business.

Tell us about your project

Our mobile app capabilities

iOS (Native)

A native app built with Swift and SwiftUI for your iPhone and iPad users. Apple ecosystem integration and disciplined App Store releases.

Android (Native)

A native app built with Kotlin and Jetpack Compose for your Android devices. Play Store publishing and Google ecosystem integration.

Cross-platform

One codebase, two platforms with React Native or Flutter. When speed is your priority, you get a result close to the native app experience.

Web App (PWA)

A mobile experience that needs no store release. The reach of the web with the speed of an app. Offline use and push notification support.

Server Infrastructure

Push notifications, user authentication, and analytics infrastructure. The invisible backbone of your mobile product.

Store Release

Before launch, we test your app on real devices with a limited test group and fix issues before they reach your users. We run the App Store and Play Store release processes end to end.

Sprint-based process

We work in sprints. A delivery every 2 weeks, with your sign-off on every delivery.

Why Vendoor Digital?

Because there's no off-the-shelf package — there's partnership.

We stand apart from the competition on three fronts: process, partnership, results.

We don't leave the job half done; we're with you all the way.

One Codebase, Two Platforms

We build iOS and Android from a single codebase, cutting cost and maintenance load in half. Native performance when you need it.

All the Way to Store Release

We manage the App Store and Google Play submission, approval, and release process. You don't deal with the technical details.

30-Day Bug Warranty

We fix production bugs free of charge for 30 days after launch; the source code and store accounts stay with you.

4 years of B2B SaaS, e-commerce, mobile, and AI experience. Process design and mobile product development for mid-sized companies.

What does mobile app development cost?

Mobile app projects from €1,999.

Scope

The number of screens and the depth of features drive the price; a simple app is not the same as a feature-rich platform.

Integrations

Connections to payment, maps, notifications or existing systems increase the development effort.

Timeline

The project schedule and the number of platforms (iOS, Android) also feed into the price.

No fixed packages — the exact price depends on scope. The first conversation is 30 minutes and free.

Prices exclude any applicable taxes.

Frequently asked questions

What does Vendoor Digital's 'Mobile Apps' cover?

iOS (native), Android (native), cross-platform (React Native or Flutter), web app (PWA), server infrastructure, and store release processes — six areas. Depending on your needs, we work in a single area or combine several.

Should I choose native or cross-platform?

The decision comes down to three questions: is speed critical (cross-platform), do you need platform-specific features (native), is budget the priority (cross-platform). We assess this together during the needs analysis.

How long does the process take?

A cross-platform MVP takes 6–12 weeks, native iOS + Android 12–24 weeks, a web app 4–8 weeks. We work in sprints and deliver a working build every 2 weeks.

How are the App Store and Play Store approval processes handled?

We manage the release processes. Approval takes 1–2 weeks on average; in case of rejection, we make the changes Apple or Google requests.

Are post-launch store optimization and marketing on your side?

No. App store optimization (ASO), ongoing store management, and marketing stay with your team. Vendoor Digital's scope runs until launch; a separate maintenance agreement can be arranged for what comes after.

Does it integrate with our existing server infrastructure?

Yes. API integration is a significant part of the work. We analyze your existing infrastructure and choose the lightest approach; if needed, we add a server layer dedicated to the mobile product (push notifications, user authentication, analytics).
