She vibe coded an iPhone app and launched it to the App Store with zero coding knowledge

Bryce Ratner Keithley, whose career has been entirely in talent and recruiting, built a consumer fitness app called Daily Hundreds and successfully launched it to the Apple App Store without any software engineering background. The app originated from a pandemic-era habit of doing 100 reps of a single exercise per day, and Bryce wanted a tool that would suggest a different exercise each day and allow her to log her reps.

Bryce began building in October using both Lovable and Replit simultaneously, ultimately sticking with Replit because a friend worked there as a director of engineering. She described her process as leveraging a 'beginner's mindset' — not knowing the boundaries of what was possible actually helped her push further. Key workflow discoveries included using Replit's plan mode before making changes, which prevented the AI from going off in unintended directions. She also relied heavily on screenshots and very literal, precise prompting to guide the AI.

One of the most distinctive features of the app is its library of AI-generated anthropomorphic animal exercise demonstration videos. Bryce developed a multi-step pipeline: she creates animal characters in Gemini with very precise positional prompts (leveraging her background as a barre instructor for accurate physical queuing), films herself performing the exercises, and then combines the animal image with her workout video using Higgsfield's Cling 3.0 motion control model. This process requires significant iteration, as the AI frequently misinterprets positioning instructions.

For getting the app into the App Store, Bryce initially heard from technical friends that she would eventually need a developer to unblock her. However, by February, new AI models made self-service possible. She used a layered Claude workflow: plain Claude as a 'technical architect' to create a plan and provide context, Claude Code as the 'software engineer' to write actual code, and the terminal to execute commands directly. She spent approximately 25-30 hours in a single weekend and got the app approved on her second submission after fixing three issues: a mislabeled parental control checkbox, a non-functioning Sign in with Apple (required for iPad compatibility), and a missing account deletion button.

In the broader conversation, Bryce reflected on talent and hiring implications, arguing that people who remain territorial about their traditional roles or resist seeing their function through a new lens will struggle. She emphasized that for technical roles especially, the human value-add has shifted — finding a working solution fastest is no longer the differentiator since AI can do that. She recommended the books 'What Got You Here Won't Get You There,' 'How Women Rise,' and Daniel Pink's 'A Whole New Mind' as relevant reading for navigating this career moment.
