Your business in your customers' pocket
A well-designed app doesn't just look good — it retains users, increases usage frequency and creates direct communication channels with your audience. We design every screen thinking about the end user and your business goals.
We develop with proven technologies like React Native and Ionic for cross-platform projects, and Swift/Kotlin for native apps when performance is critical. The result: fast, stable apps successfully published in all three stores.
What we build
Types of Apps We Develop
From mass consumer apps to internal tools for your team.
Native iOS and Android apps
Built in Swift (iOS) and Kotlin (Android) for maximum performance when a native experience is critical for your product.
Cross-platform hybrid apps
React Native and Ionic to reach iOS, Android and Huawei with a single codebase — lower cost, same visual result.
Published in all 3 stores
We manage the complete publication process on App Store, Google Play and Huawei AppGallery, including reviews.
Push notifications and messaging
Personalized notifications, in-app messaging and WhatsApp integration to keep your users engaged.
API and ERP integrations
We connect your app to existing systems: ERP, CRM, payment gateways, maps, cameras and any external service.
Mobile-first UX/UI design
Every screen designed specifically for fingers and small screens — not a web design adapted for mobile.
Why apps with Nexxus?
Real code, not low-code
We develop with real code — no Bubble, no AppGyver. Your app is yours and can evolve without platform limitations.
Published in all 3 stores
We cover App Store, Google Play and Huawei AppGallery. Many competitors ignore Huawei, which has millions of users.
Agile post-launch updates
Once in production, we implement new features and fixes in short 2-to-4-week cycles.
Native performance
We optimize animations, data loading and battery usage so the app feels fast on mid-range devices.
Offline-first by default
Core features work without connection and sync automatically when internet returns.
NDA and confidentiality
We sign a non-disclosure agreement before starting. Your idea, your code and your business model are completely confidential.
What's the Process?
From idea to the stores, with reviews at every stage.
01
Definition
We map features, user flows, required integrations and the most suitable technology for your use case.
02
UX/UI Design
Interactive prototype of all screens to validate the experience before writing a single line of code.
03
Development
Two-week sprints with a demo at the end of each one. Beta version access on your device throughout the process.
04
Publication
We submit the app for review in each store, handle any rejections and deliver the configured accounts to you.
