RAG vs Fine-Tuning: Choosing the Right LLM Approach for Your Product
Both RAG and fine-tuning improve LLM performance on your specific use case — but they solve different problems. Here's how to choose.

THE CHALLENGE
Sound familiar?
- Your iOS app idea is stuck because you lack Swift expertise
- Your existing iOS app is slow and getting one-star App Store reviews
- You need AI features in your iOS app but lack Core ML experience
- Your contractor built an iOS app that crashes on new iOS versions
- You're not sure how to navigate App Store review guidelines
OUR APPROACH
How we solve it
We build production-grade iOS apps in Swift and SwiftUI, with AI features integrated via Core ML, OpenAI, or Anthropic APIs. From architecture through App Store submission — one team, full ownership.
What you receive
- Native iOS app built in Swift/SwiftUI
- Core ML or cloud AI feature integration
- App Store submission package (screenshots, metadata, compliance review)
- TestFlight beta program setup and management
- Fastlane CI/CD pipeline for automated builds
- Unit and UI test coverage
- Documentation and design files
OUTCOMES
What you walk away with
01
App Store-ready iOS app shipped on time
02
AI features that work reliably on device and in the cloud
03
Clean Swift codebase your team can maintain and extend
04
App Store submission handled end-to-end — no last-minute surprises
05
Performance benchmarks met before launch

02
Foundation Build
App architecture, navigation, authentication, and core data layer.
03
Feature Development
App screens, AI integrations, third-party SDKs, and backend API connections.
04
AI Integration
Core ML model integration, cloud AI feature connections, and on-device inference optimization.
05
App Store Release
TestFlight beta, App Store review submission, staged release, and post-launch monitoring.
Is this right for you?
Best suited for
- Startups launching their first iOS product
- Teams that need AI features in a native iOS experience
- Founders who've had a failed iOS app from a previous contractor
- Products where iOS is the primary platform and performance matters
Not the right fit for
- Projects where a cross-platform React Native app would serve the same need
- Teams with an existing iOS codebase that only needs augmentation
- Projects requiring deep custom hardware integration beyond standard iOS APIs
Engineering Stack

Both. We use SwiftUI for new projects and new screens where appropriate, and UIKit for legacy integration. Stack decisions are driven by your project requirements, not our preferences.
We manage the full App Store submission process — screenshots, metadata, privacy manifests, compliance review, and responding to App Store reviewer feedback. Submission is included in all iOS engagements.
Yes. We add Core ML models, cloud AI integrations, or on-device inference to existing iOS apps. We start with a technical audit to understand the current architecture before proposing an integration approach.
