AI-Native App Development
From idea to App Store in 90 days using AI agents, cloud infrastructure, and proven frameworks. We build intelligent iOS apps faster than traditional agencies — at a fraction of the cost.
From Idea to App Store in 90 Days
In February 2026, Mark Lunnemann had an idea: an AI-powered interior design app that could transform any room from a single photo. By May 2026 — just 3 months and 12 days later — Aspire Interiors was live on the App Store in 175 countries.

How long does it take to build an AI-powered iOS app?
Most projects go from idea to App Store in 90 days. Aspire Interiors took 3 months and 12 days. Timeline depends on complexity: a simple AI feature takes 4-6 weeks. A full app with subscriptions, user accounts, and AI processing takes 10-12 weeks.
How much does AI app development cost?
Projects start from £15,000 for a focused AI-powered iOS app. This includes backend infrastructure (Supabase + Google Cloud), iOS development (Swift UI), AI integration (Vertex AI or similar), App Store submission, and 30 days post-launch support. Complex apps with multiple AI features, subscriptions, and custom UI cost £25,000-£40,000. We provide a fixed quote after the discovery phase — no hidden fees.
Do you only build iOS apps?
Currently yes — iOS is our specialty and the fastest path to market. Every app we build uses Swift and SwiftUI for native performance. We can add Android later using React Native or Flutter, but we recommend starting with iOS to validate your idea first. Aspire Interiors launched iOS-only and is now planning Android based on user demand.
Can you help with App Store submission?
Yes — and it's included in every project. We handle screenshots, metadata, keywords, review notes, and demo accounts. Aspire Interiors was rejected once for missing subscription disclosures. We fixed it in 24 hours and got approved on resubmission. We know Apple's guidelines inside out.
What happens after launch?
Every project includes 30 days of post-launch support for bug fixes and tweaks. After that, we offer monthly retainers for ongoing development, feature additions, and App Store optimisation. Aspire Interiors is on a monthly retainer for new features.
How is an AI-native team different from a traditional agency?
Traditional agencies bill by the hour and scale by hiring more people. We scale by hiring AI agents that generate content, write code, and test features 24/7. This means faster delivery (48-hour feature cycles vs 2-week sprints), lower costs, and higher quality. Aspire Interiors was built by 1 human + 3 AI employees — a team that would cost £200K+ at a traditional agency.
Can I see the app you built?
Yes — Aspire Interiors is live on the App Store right now. Search 'Aspire Interiors' on the App Store or visit aspire-interiors.com. You can download it free, try the AI room design features, and see exactly what we build.
