From strategy to App Store — we build native iOS apps you can actually ship and maintain. One team handles design, Swift development, submission, and post-launch support, so you’re not managing multiple vendors.
Native applications built in Swift and SwiftUI around your specific business workflows, not a generic template. Includes backend and API integration, App Store deployment, and an architecture built to be maintained, not just shipped once.
Interfaces designed to Apple’s Human Interface Guidelines, tested for usability before development begins, and adapted across iPhone and iPad screen sizes rather than simply scaled up.
Native watchOS companion apps — complications, notifications, and HealthKit-connected workout or health use cases — built to sync with your iPhone app rather than exist as a separate product.
Spatial computing capability using visionOS and SwiftUI for teams exploring immersive or 3D experiences on Apple Vision Pro. We scope these projects individually given the platform’s early maturity.
Migrate Objective-C to Swift, UIKit to SwiftUI, and legacy architecture to modern patterns. Timelines depend on codebase size, test coverage, dependencies, and how much needs replacing.
On-device AI using Apple’s on-device frameworks alongside Core ML, Vision, and Speech, plus cloud LLM integration via OpenAI, Anthropic, and Gemini where deeper reasoning is needed.
iOS cost is driven by scope, not a fixed menu — screens, workflows, iPhone/iPad support, backend architecture, integrations, Apple Pay and StoreKit, HealthKit, AI, an Apple Watch companion, security, and compliance all move the number. The tiers below are planning guides — every engagement gets a written, itemized estimate after a free discovery call.
Typical timeline: 6–10 weeks
Best for validating an idea with real users before investing in scale.
Typical timeline: 3–5 months
Best for funded startups and SMEs launching a full commercial product.
Typical timeline: 6+ months
Best for enterprises and regulated industries.
Cost decisions happen in the first two weeks of a project, before most of the code is written. Every factor below is scoped and priced individually during discovery.
An iPhone-only app costs less than a universal iPhone + iPad build. Extending to Apple Watch, Mac Catalyst, or visionOS adds scope, sized during discovery.
A pure Swift/SwiftUI build generally costs more than a Flutter cross-platform app, in exchange for deeper Apple ecosystem integration.
Apple HIG-compliant UI ships fast. Custom animation, spatial layouts, or ARKit interfaces add design and engineering time.
StoreKit, Sign in with Apple, HealthKit, and HomeKit are quick individually. HIPAA-compliant or fintech integrations carry more overhead.
On-device Core ML models and Vision-based recognition add development and running cost we model before you commit.
HIPAA, PCI-DSS, SOC 2, and GDPR add architecture and audit work measured in weeks.
An iOS MVP typically reaches App Store submission in 6–10 weeks; growth-stage products take 3–5 months; enterprise Apple platforms run 6+ months depending on integrations and complexity.
| Phase | MVP iPhone App | Mid-Complexity | Enterprise iOS |
|---|---|---|---|
| Discovery & Validation | 3–5 days | 1–2 weeks | 3–4 weeks |
| UI/UX Design (HIG-compliant) | 1–2 weeks | 3–5 weeks | 6–10 weeks |
| iOS Development (Swift / SwiftUI) | 3–4 weeks | 6–10 weeks | 10–16 weeks |
| Backend & APIs | 2–3 weeks | 4–8 weeks | 10–14 weeks |
| QA & TestFlight | 1 week | 2–3 weeks | 4–6 weeks |
| App Store Submission | 3–5 days | 1 week | 1–2 weeks |
| Total Timeline | 6–8 weeks | 12–16 weeks | 18–24 weeks |
Native iOS development is especially valuable in industries where premium user experience, security, payments, health integrations, real-time features, or deep access to Apple’s ecosystem can materially improve the product.

Agile Scrum, two-week sprints, regular demos, and testable builds throughout development — so progress is something you can review and experience, not just read about.
We interrogate your idea before writing a line of code — market fit, user personas, feature prioritization, and a technical architecture document you own even if you never hire us.
A written iOS app brief with validated concept, prioritized feature list, and a technical architecture document — clarity before a single line of Swift is written.
We lock the Swift/SwiftUI tech stack, define milestones, and map resource allocation — so scope changes later don’t blow up your timeline.
A structured project plan with dated milestones and a fixed-price proposal within 24 hours of discovery.
Clickable Figma prototypes tested with real users before development starts — because fixing a flow in design costs 10x less than fixing it in code.
A tested, user-validated iPhone and iPad interface, following Apple’s HIG, ready for development with zero rework guesswork.
Two-week sprints with a working build demo every cycle. You watch your app take shape and steer priorities in real time through a shared project board.
Visibility into every sprint, a working build every two weeks, and clean, documented Swift code with secure API architecture.
Automated test suites, manual QA on real devices, load testing, and security review — because your App Store rating launches with your first release.
A stable, secure, thoroughly tested app with a documented QA report before submission.
App Store submission, listing optimization, and launch-day monitoring — we’ve navigated every rejection reason so you don’t have to.
A fully launched iOS app with 90 days of free post-launch support, then flexible maintenance plans as your user base grows.
Apple’s current toolchain paired with battle-tested architecture patterns — chosen to keep the app fast in production and easy to maintain as Apple ships new OS versions.
Native iOS development provides direct access to Apple’s latest platform APIs and device capabilities, making it particularly valuable when deep ecosystem integration is central to the product.
On-device Core ML models and the Vision framework for real-time image recognition and predictive features that run on-device without sending data to external servers. See our broader AI integration services.
Firestore real-time database, Firebase Auth, Cloud Functions, and push notifications via APNs — with AWS Amplify and CloudKit for enterprise-scale needs, sized to expected traffic during discovery.
WebSocket connections and Apple’s Live Activities API power real-time chat, live location tracking, Dynamic Island updates, and instant push notifications.
StoreKit for in-app purchases, auto-renewable subscriptions, and promotional offers built to App Store guidelines, plus Stripe, Apple Pay, and Razorpay with PCI-DSS-aligned checkout flows.
Home Screen and Lock Screen widgets, App Clips for instant lightweight launch experiences via QR or NFC, and iMessage extensions that extend your app beyond the main screen.
Augmented reality experiences using ARKit and RealityKit — product visualization, interior design tools, and training overlays — with capability to extend into visionOS spatial layouts for Vision Pro.

As specialists within the broader mobile app development ecosystem, we focus on what Apple’s platforms do well — deep ecosystem integration, App Store delivery, and long-term product maintenance. Here’s what that means in practice:
Book a Discovery Call
Projects are built in Swift and SwiftUI by engineers who work directly with Apple’s current frameworks rather than legacy patterns carried over from older iOS versions.
Projects are led by experienced iOS engineers who work directly with clients throughout discovery, implementation, and release — not through an account layer.
iPhone, iPad, and Apple Watch — with Vision Pro capability for teams ready to explore spatial computing. We build for the platform your product actually needs, not just the iPhone screen.
Every engagement starts with discovery that produces scope, flows, and an architecture recommendation you own — so budget goes to a validated plan, not assumptions.
Our team prepares App Store submissions around Apple’s current review, privacy, entitlement, and metadata requirements and manages review feedback when Apple requests changes.
Source code, designs, project documentation, and agreed intellectual property are transferred according to the project contract. Wherever practical, your Apple Developer account and repositories stay under your ownership from the start rather than being handed over later.
Annual iOS version upgrades, Swift migrations, and dependency updates handled on an ongoing basis, so the app you launch keeps working as Apple ships new OS releases.
We take over existing iOS codebases from other vendors and modernize legacy Objective-C or UIKit apps — starting with an honest audit before quoting anything.
