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.

Count every stunt rep. Know your hit rate. HitRate is the stunt-outcome counter for cheerleading. Tap once per rep — hit, bobble, building fall, or major fall — and your dashboard builds itself. FOR ATHLETES Track the skills YOU'RE working on. Create your own list — lib, stretch, full up, anything — and log every rep at practice. Watch your hit rate climb across the season. FOR COACHES Switch to coach mode and track every stunt group on the floor. See which groups are locked in and which need reps, ranked automatically. THE DASHBOARD • Hit rate at a glance — today, this week, or all-time • Trend line across your recent sessions • Skills and groups ranked by hit rate, with movement vs last session • Auto-written takeaways: what led the way, what to tighten next • Session tape: every rep of your latest practice on one strip STUNT CARDS Turn your numbers into holographic trading cards. Earn milestone cards from COMMON to LEGENDARY — rarity is set by how hard each one is to earn, like 1,000 reps logged or 25 hits in a row. There are even DUBIOUS HONOR cards for the falls. Save them, copy them, or post them to Instagram. BUILT FOR THE GYM • One-tap logging with big targets — made for fast hands at practice • Rename outcomes to match your gym's language • Undo mis-taps instantly • CSV export of every rep • Works completely offline — your data never leaves your phone No accounts. No ads. No tracking. Just counts.

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.
From the Build Kit assessment.
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.
