THE EXPERIMENT
Thrive started as a question: how far could I get designing and building a real iOS wellness app using only Claude as my collaborator? Built as part of a hands-on workshop with an experienced vibe coder, I learned how to prompt well — then put it into practice. No Figma. No handoff. Just conversation, iteration, and a working prototype.
the PROCESS
Prompting well turned out to be the core design skill. I started every session with a clear goal and a defined outcome — then had Claude recheck its own work repeatedly, catching inconsistencies before they compounded. I also learned the practical side: how to save and version files, structure prompts for reproducibility, and keep context alive across long sessions. The result was a real iterative loop — closer to designing with a collaborator than using a tool.
THE APP
Thrive is built around a to-do list — because that's how I actually live. Everything in the app is a checkable item. Morning check-in. Log breakfast. Gym. Evening reflection. The satisfaction of ticking things off isn't just motivational — it's the interaction model. Your whole day, condensed into a list you can work through and complete.
What makes it smarter than a regular to-do list is what happens when you tap each item. Check-ins open into mood sliders and sleep logs. Food tasks open a camera that reads your macros. Every checkbox hides a moment of intentional input — without ever feeling like a form.
The app also has a conversational morning agent — tap and it reads your day out loud, then listens. Add tasks, ask how you're doing, or just hear your schedule spoken back to you. Voice or text, whichever feels right.
By the end of the day, the analytics page turns all those checked boxes into patterns — mood trends, sleep quality, nutrition, and fitness in one place. The kind of view that usually takes three separate apps to assemble.
learnings
Prompting is a design skill
being specific about intent and outcome produced better results than open-ended requests. The quality of the output reflected the quality of the thinking behind the prompt
Going back to basics is a superpower
when things got too complex for Claude to handle cleanly, stripping back to fundamentals produced better outcomes. Knowing when to simplify is a core design skill that AI can't replace
Context management is everything
in long sessions, Claude would lose the thread. Re-anchoring with clear summaries and goals became as important as the prompts themselves
