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.

OnPoint turns your Apple Watch into a courtside referee. Score with a tap, undo with a double-tap, and hear the score announced out loud. Tennis, padel, and pickleball — every rule, every format, one app. SCORE YOUR WAY • Tap your Apple Watch to score. Sub-one-second with haptic feedback. • Double-tap to undo. No menus, no hassle. • Action Button on Apple Watch Ultra: 1 press = your team, 2 = opponent, 3 = undo. • Bluetooth remote: pair any BLE shutter button and score from anywhere on court. • Digital Crown scoring: scroll to score without looking. HEAR EVERY POINT Connect any Bluetooth speaker and OnPoint announces the score after every point in 5 languages. The whole court hears it. THREE SPORTS, ALL THE RULES • Tennis: standard advantage, no-advantage deuce, best of 1/3/5 sets. • Padel: golden point, star point (FIP 2026), first to 9, match tiebreak to 10. • Pickleball: rally scoring, side-out (0-0-2), freeze rule, win-by-2 toggle. 11, 15, or 21 points. KNOW YOUR GAME • Performance analysis: win rates by intensity zone, heart rate, and shot type. • Shot classification: forehand, backhand, overhead, and volley tracked per swing. • Power analytics: G-force per shot — see if your power drops as you fatigue. • Heart rate tracking: Apple Health style range bars across the match. • Point-by-point detail table: tap to see every point with HR, swings, and shots. • Match history: every match saved with full stats. DESIGNED FOR THE COURT • 7 court themes: Team Colors, Grass Court, Clay, Padel Court, Dark, Neon, High Contrast. • Side swap alerts: "Change ends" announced every 2 games. • Player roster: save your squad, pick teams, hit the court. • Works offline. No internet required during play. NO SUBSCRIPTIONS. JUST PLAY. One-time purchase. No ads, no paywalls, no recurring charges. Ever.

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.
