Your first Build Kit is free with a verified email.
Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Inside Outside Health is a safe space for athletes - built by one who needed it and couldn't find it. Every athlete has the moment. The injury year. The season on the bench. The practice where you realized you'd stopped enjoying the thing that made you who you are. Most of us carry it alone, because saying "I'm not okay" feels like it could cost you your spot. Inside Outside Health exists so you don't have to. READ STORIES FROM ATHLETES WHO'VE BEEN THERE Real stories from real athletes about injury, burnout, anxiety, identity and coming back - written for the person who's in it right now. Every story is read by our team before it's published. Save the ones that get you through. SHARE YOURS, ON YOUR TERMS Post under your name, your location, or fully anonymously - the app never reveals who wrote an anonymous story. Publish to the public feed or to a community you've joined, and take a story down whenever you want. A JOURNAL THAT SHOWS YOU WHETHER IT HELPED Pick what's on your mind, note how you feel, write it out, then check in again. Your journal tracks your mood before and after every entry, so over a month you can see what writing actually does for you. Missed a day? Fill it in from the calendar. Every entry is private unless you choose to share it anonymously. RESOURCES MADE FOR ATHLETES Podcasts, videos and playlists on the mental side of sport, sorted toward the sports you play - plus in-app exercises like box breathing for the ten minutes before a race, or a quick color match to get out of your own head. BUILD YOUR OWN TOOLKIT Collect the stories, journal entries and resources that help into toolkits you can step through when you need them: race week, coming back from an injury, a bad-day reset. They're yours alone. SUPPORT WHEN IT'S SERIOUS Crisis lines and text services are one tap away from every part of the app. If you're in immediate danger, call 911. The 988 Suicide & Crisis Lifeline is available 24/7 by call or text. Inside Outside Health is a community and a set of tools, not a substitute for a therapist, doctor or athletic trainer. If you're struggling, please reach out to a professional - and bring what you've written here with you. YOUR PRIVACY Journal entries are private by default. Nobody on our team can read one unless you switch on "Share anonymously" for that entry. You can export everything you've written, or delete your account, at any time. You are not your stats. You are not your injury. You are not the bad play at minute 12. Athletes don't need to be fixed - they need to be heard. Inside Outside Health is for athletes 18 and older.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
