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.

Run For Real Stakes Put something on the line and go run. Join a race, commit to a weekly mileage goal, and log your runs. Clear your goal and your entry comes back in full. Miss it, and your entry is split among the runners who made it. Nobody to beat but the goal you agreed to. HOW IT WORKS • Pick a race and a weekly distance goal • Track runs with GPS • Clear your goal every week to keep your full entry • Runners who miss fund the runners who finish BUILT FOR PEOPLE WHO ACTUALLY RUN • Live GPS tracking with pace, distance, and route • Lock Screen and Dynamic Island updates while you run • Every run verified server-side, so the standings mean something • Streaks, history, and a receipt for every race you've entered Free races are available to everyone. No ranking to climb, no opponents to outrun, just the goal you set. SUBSCRIPTIONS (OPTIONAL) Renno+ — $6.99/month No processing fees, join two races at the same time, host public races, and more!

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.
