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.

Tennis Score Wizard is a complete tennis scorekeeper built for Apple Watch. Score on your wrist with automatic games, sets, tie-breaks and serving order. Clear controls, haptics and undo help you stay focused. FLEXIBLE MATCH SETUP • Singles and doubles • One Set, Best of 3, or Best of 5 • Traditional advantage and tie-break sets • Official Short Sets • Custom Set with configurable game target, win-by rule, tie-break start, and tie-break target • Standard Game or No-Ad scoring, independently from the set format • Match Tie-Break to 7 or 10 when the sets are tied • First-server selection with an animated coin toss • Optional Apple Health workout recording RIVALRIES OPPONENTS — PRO REQUIRED Standalone scoring, history, statistics, workouts, and complications remain fully usable without Pro. Saved Rivalries opponents require the separately available Tennis Score Wizard Pro app. Create and manage players on iPhone in Pro. When both apps use the same Apple Account for iCloud, those players become available in Pro’s Apple Watch app and this standalone Apple Watch app. If you already own this standalone app, you can add Pro later and use the players you create across both Apple Watch apps. Choose a saved player before a Singles match or continue as Guest. The selected short name appears during play and in Watch history, and the completed match stays linked to that player’s Head-to-Head record in Pro. LIVE MATCH SCORING Track points, games, sets, server order, and serve position without interrupting play. Tennis Score Wizard automatically updates the score, switches servers when required, and provides side-change reminders. MATCH HISTORY Every completed or stopped match can be reviewed directly on Apple Watch. Filter History by All, Singles, or Doubles and review the match format, custom rules, result, completed and unfinished sets, total games, duration, total points, workout status, and full set-by-set score. AUTOMATIC MATCH STATISTICS Recorded point-by-point matches generate statistics from your scoring taps. Match Stats: • Total points played • Points won by each side • Point win rate • Tie-break and Match Tie-Break records Serve & Return: • Service games won • Service points won • Return games won • Return points won Match Flow: • Recorded games • Longest game • Average points per game • Match duration Break Points: • Break points faced • Break points saved • Break-point chances • Break points converted APPLE HEALTH WORKOUTS When you enable Record Workout and grant permission, Tennis Score Wizard records your match as a tennis workout in Apple Health. View your live heart rate during play. After the workout is saved, review: • Workout duration • Average heart rate • Maximum heart rate • Active energy Saved workouts are also available in the Apple Health and Fitness apps. DESIGNED FOR APPLE WATCH • Responsive layouts for compact and larger Apple Watch displays • Clear completed and stopped match cards with soft outcome lighting • Apple Watch complication for quick launch • Haptic feedback throughout setup and scoring • Undo last point • Switch server during an active match • Delete individual matches or clear your complete history • Private iCloud synchronization for match history • No in-app account or sign-in required • No developer-operated servers • Explore month and year recaps in Watch History, with activity, comparisons and achievements. • Manually added matches and later corrections from Tennis Score Wizard Pro on iPhone sync to Watch history through private iCloud using the same Apple Account. Manually entered matches are labeled and do not add unrecorded point-by-point or workout data. Scores recorded on Apple Watch remain protected from manual editing. Match Flow shows game-by-game momentum and running scores when recorded point history is available. Tennis Score Wizard Pro Pro includes the full Apple Watch scoring app and match analysis on iPhone. No separate Standalone purchase is needed.

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.
