Building an iPhone app with zero technical skills | Bryce Rattner Keithley

Bryce Rattner Keithley has spent her career in talent and recruiting, working with technical leaders but never writing a line of code herself. Yet she managed to build Daily Hundred—a fitness app featuring custom AI-generated videos of anthropomorphic animals demonstrating exercises—and ship it to the App Store before her software engineer friends. Using Replit, Claude, Gemini, and a relentless beginner’s mindset, Bryce proves that in the AI era, execution is no longer the constraint on good ideas.

What you’ll learn:

1. How to build and ship an iPhone app using Replit without any coding knowledge
2. The step-by-step process for creating custom AI-generated workout videos by combining Gemini images with real exercise footage
3. How to use Claude as your technical architect and Claude Code as your software engineer
4. How to navigate App Store submission requirements (including fixing rejection feedback)
5. Why being hyper-literal in your prompts unlocks better AI results
6. Why a beginner’s mind is actually an advantage when building with AI tools
