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.

AIRTIME turns your iPhone and Apple Watch into a real vertical jump and sprint lab. Most athletes guess their numbers. AIRTIME measures them, then coaches you to improve. VERTICAL JUMP, MEASURED - AR zone calibration sets a baseline for your space before you jump - Standing, one-foot, and two-foot jumps (combine-standard) - Apple Watch motion sensors record your takeoff at 100Hz for an authoritative height - On-device Apple Vision pose tracking plus AI apex analysis back it up - A synced jump cue counts your phone and Watch down to one shared instant, so nothing drifts SPRINT TESTING - Time your sprint with the iPhone finish gate - Track your 40 and short-sprint progress over time AI COACHING (AIRTIME Pro) - A personal AI trainer that reads your results and builds your plan - Coaching notes on each attempt - A training cycle with deload prediction so you peak instead of burning out MORE - Simulcam ghost overlay to compare attempts side by side - Game Mode challenges - Global jump history and leaderboard - Workout logging on iPhone and Apple Watch - Your data restores after a reinstall An Apple Watch is strongly recommended for the most accurate jump height. Without a Watch, AIRTIME gives you a vision-based estimate, and the rest of the app still works. Built for hoopers, football and track athletes, volleyball players, trainers, and anyone chasing more hops and more speed. Download, calibrate, and get your first real number today. ——— AIRTIME Pro is an auto-renewable subscription (US$32.99/month). Payment is charged to your Apple Account at purchase confirmation.

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.
