Cross-Platform Development
For faster results and cost savings, our developers specialize in cross-platform app development for iOS and Android. Using technologies like Kotlin Multiplatform (KMP), Compose Multiplatform (CMP), Flutter, and React Native, we create apps from a single codebase, and you don’t need to hire separate native teams, making it easier to scale through team augmentation or building a remote tech team.
UI/UX Design
We design engaging, user-friendly interfaces aligned with your brand. Our iOS UI/UX services focus on research-driven design to boost user satisfaction, retention, and app awareness. You can outsource developers to handle the entire design and implementation process seamlessly.

Our Development Process
We start by listening to your goals and specific needs, ensuring we understand your app’s vision clearly.
Based on the gathered information, you get a detailed project plan, including a precise timeline, cost estimation, and defined milestones, ensuring full transparency.
Our team begins the design and development phase, keeping you involved at every stage with regular progress updates and the opportunity for feedback to ensure alignment with your goals.
Before launch, the app goes through rigorous testing to ensure it meets the highest standards of functionality, performance, and user experience, eliminating bugs or issues.
Once everything is ready, we take care of the deployment process, making sure it’s properly set up on app stores or other platforms.
After launch, we offer continuous support to ensure your app stays up-to-date and runs smoothly, adapting to your needs over time.
FAQ
Aetherius provides senior iOS engineers for team augmentation and full-cycle development engagements. We build custom iOS apps in Swift and SwiftUI, handle App Store submission, and cover UI/UX design, consulting, and ongoing maintenance. You can hire individual developers or bring in a full team depending on what your project needs.
In most cases, we present pre-vetted senior iOS candidates within 5-10 business days. Our developers are experienced in jumping into existing codebases, understanding the architecture quickly, and contributing without a long ramp-up period.
Aetherius maintains a pool of senior iOS engineers available for long-term team augmentation. We match based on your exact stack, project context, and seniority requirement, not just who's available. Get in touch and we'll present matching profiles within days.
It depends on your existing codebase, team structure, and client requirements:
- Native iOS (Swift/SwiftUI): best when you need full access to Apple platform APIs, maximum performance, or your client is Apple-first
- KMP: best when you want to share business logic across iOS and Android while keeping native UI on both platforms
- Flutter / React Native: best when UI consistency across platforms and faster delivery are the priority
If you're unsure, our team can consult on the right approach based on your actual constraints.
Every developer goes through technical screening that covers Swift architecture patterns, code quality, and the ability to work independently in complex, enterprise-grade codebases. We don't label mid-level developers as seniors. If a profile doesn't precisely match your requirements, we say so before you meet them.
Yes. Aetherius developers are experienced in white-label delivery; they align with your workflows, communication standards, and team culture. They operate as your team members, not as an external vendor.
Pricing depends on seniority level and engagement model. We don't publish flat rates because every project is different, but pricing is always transparent with no hidden fees. Use the Aetherius Cost Calculator for a custom estimate, or get in touch, and we'll break it down based on your actual requirements.
Not necessarily. KMP creates a structural challenge that most people don't anticipate; the iOS side often becomes the bottleneck because native iOS developers aren't familiar with the shared Kotlin layer. Aetherius has iOS developers who are experienced with KMP integrations, so they can work across both the native iOS layer and the shared codebase without slowing the project down.
