AI mobile app development
AI in your mobile app, built to ship
I add AI to your mobile app with OpenAI or Anthropic where they fit, and evaluate on-device options around privacy and performance. You work directly with the engineer building it.
What's included
The pieces that make up a ai in your mobile app, built to ship engagement, and what each one does for your project.
Chat and conversational AI
Chat built on an OpenAI or Anthropic integration chosen for the product. It remembers the conversation, streams replies, and follows a system prompt written in your brand voice.
- •OpenAI or Anthropic integration
- •Multi-turn conversations with context
- •Streaming responses for low latency
- •Custom system prompts
- •Conversation history & preferences
Vision and image recognition
Read text from images, spot objects, search by picture, and describe a scene. The model and runtime are chosen around the product's privacy and performance needs.
- •OCR (text extraction from images)
- •Object detection & classification
- •Face recognition & emotion analysis
- •Visual search (find similar images)
- •Scene understanding & captioning
On-device AI models
Models that run on the phone, with no internet needed. Data never leaves the device, so it stays private. I shrink the model so it runs well on mobile.
- •On-device options evaluated when they fit
- •Offline AI functionality
- •Private AI (data stays on device)
- •Battery-efficient inference
React Native integration
AI wired into your React Native app with TypeScript. Real state handling, real error handling, and native modules where the JS bridge is too slow.
- •React Native + Expo compatibility
- •TypeScript for type safety
- •Native AI module integration
- •Tuned for iOS & Android
Howitruns
Four phases, mapped to the actual work. Each phase ends with something you can review.
01
Design the AI architecture
Pin down where AI helps, pick the right models, plan the API setup and the cost side, and design how the AI feels to use.
02
Build and integrate
Wire in the AI APIs, put a backend proxy in front to keep keys safe, stream the responses, add error handling and fallbacks, and tune the prompts for mobile.
03
Make it fast
Cut response times, add caching, batch requests, watch battery use, and test prompts against each other to see what works.
04
Launch and watch
Ship it, track cost and usage, add safety filters and content moderation, and make sure it passes App Store review.

Want to talk through ai in your mobile app, built to ship?
Tell me what you're building. I'll tell you what's realistic, what it takes, and whether ai in your mobile app, built to ship is the right fit. If it isn't, I'll say so.
A 30-minute scoping call (no slide deck)
A short written summary of the project shape
No obligation, no follow-up sales sequence
I usually reply within a working day. Conversations stay confidential.
Fixed-scope pricing. No setup fees. Stop anytime between phases.
