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.

Swing your wrist. Hear the crack. Bataboom! turns your Apple Watch into a bat. Swing your arms like you're at the plate and your watch answers instantly with the crack of the bat, a roaring crowd and a play-by-play call. No bat, no ball, no screen to watch while you swing. FREE SWING Swing any time. Every swing is a hit: base hits, doubles, triples and home runs, with exit velocity and distance. Hit home runs back to back and the crowd, the organ and the announcer keep getting louder. HR CHALLENGE The real game. Listen to the pitch: the whoosh gets louder and peaks at the perfect moment to swing. Time it right and swing hard and fast for a home run. Swing early and you pull it, late and it goes the other way. Ten chances per round: a home run or a foul keeps your chance, anything else uses one. Easy throws slow pitches, Pro throws mostly fastballs. After every hit, see where it landed on the field. PASS & PLAY Two to four players take turns on one watch. Five chances each, then the standings and a victory cheer for the winner. MEET LACES Laces is a baseball whose red seams are its eyebrows. It squints at the pitcher, spins after a home run, gets dizzy on a strike and dozes off when you stop swinging. LOCKER ROOM Unlock 12 items by playing HR Challenge: bats with their own sound, a fireball, a glow ball, a big-league crowd, a night game with fireworks, and outfits for Laces. Everything is earned by playing. Nothing is for sale. GAME CENTER Leaderboards for home runs per round on each difficulty and for your longest home run, plus achievements. IPHONE COMPANION Your stats, a chart of every round and a spray chart of where your hits land. Change your gear from the iPhone, get home-run tips, and share a card of your longest home run. GOOD TO KNOW • Made for Apple Watch. Play works without your iPhone nearby. • Clear the space around you and tighten your band before you swing. • Distances and speeds are fun estimates, not measurements. • No ads, no in-app purchases, no accounts, no data collected. • Apple Health: while you play, the app can record a Baseball workout so the game keeps running when your screen sleeps. It only writes workouts and reads no health data. You can turn it off in Settings. • Your progress is backed up in your iCloud and comes back if you reinstall or get a new watch. • English, Japanese, Korean, Traditional Chinese, Simplified Chinese, Spanish and French.

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.
