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 — Brought to you by: WorkOS [https://workos.com/?utm_source=lennys_howiai&utm_medium=podcast&utm_campaign=q22025]—Make your app enterprise-ready today Metaview [https://www.metaview.ai/home/how-i-ai]—The agentic recruiting platform for winning teams — In this episode, we cover: (00:00) Introduction to Bryce and Daily Hundred (04:48) Building with Replit (06:16) The beginner’s mindset advantage (11:17) Creating anthropomorphic animals (22:55) Moving from static image to video (27:15) The floating genie and other anthropomorphic animal generations (30:46) Shifting from web app to App Store submission (36:24) User feedback (37:41) Lightning round and final thoughts — Tools referenced: • Replit: https://replit.com/ [https://replit.com/] • Lovable: https://lovable.dev/ [https://lovable.dev/] • Claude: https://claude.ai/ [https://claude.ai/] • Claude Code: https://claude.ai/code [https://claude.ai/code] • Gemini: https://gemini.google.com/ [https://gemini.google.com/] • Higgsfield: https://higgsfield.ai/ [https://higgsfield.ai/] • Kling: https://kling.ai/ [https://kling.ai/] • Railway: https://railway.app/ [https://railway.app/] • TestFlight: https://developer.apple.com/testflight/ [https://developer.apple.com/testflight/] — Other references: • How a 91-year-old vibe coded a complex event management system using Claude and Replit | John Blackman: https://www.lennysnewsletter.com/p/how-a-91-year-old-vibe-coded-a-complex [https://www.lennysnewsletter.com/p/how-a-91-year-old-vibe-coded-a-complex] • What Got You Here Won’t Get You There: https://www.amazon.com/What-Got-Here-Wont-There/dp/1401301304 [https://www.amazon.com/What-Got-Here-Wont-There/dp/1401301304] • How Women Rise: https://www.amazon.com/How-Women-Rise-Holding-Careers/dp/0316440124 [https://www.amazon.com/How-Women-Rise-Holding-Careers/dp/0316440124] • A Whole New Mind: https://www.amazon.com/Whole-New-Mind-Right-Brainers-Future/dp/1594481717 [https://www.amazon.com/Whole-New-Mind-Right-Brainers-Future/dp/1594481717] • How to Win Friends and Influence People: https://www.amazon.com/How-Win-Friends-Influence-People/dp/0671027034 [https://www.amazon.com/How-Win-Friends-Influence-People/dp/0671027034] — Where to find Bryce Rattner Keithley: LinkedIn: https://www.linkedin.com/in/brycerattner/ [https://www.linkedin.com/in/brycerattner/] GitHub: https://github.com/brk-bot/ [https://github.com/brk-bot/] Daily Hundred on the App Store: https://apps.apple.com/us/app/daily100-fitness-challenge/id6762108062 [https://apps.apple.com/us/app/daily100-fitness-challenge/id6762108062] — Where to find Claire Vo: ChatPRD: https://www.chatprd.ai/ [https://www.chatprd.ai/] Website: https://clairevo.com/ [https://clairevo.com/] LinkedIn: https://www.linkedin.com/in/clairevo/ [https://www.linkedin.com/in/clairevo/] X: https://x.com/clairevo [https://x.com/clairevo] — Production and marketing by https://penname.co/ [https://penname.co/].
