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.

Meet Toothify - your Apple Watch’s secret mission: cleaner teeth. Let’s be real. Most brushing timers are glorified stopwatches. Toothify actually coaches you - breaking your 2 or more minutes into perfectly timed zones with gentle wrist buzzes to keep your brushing even, effective, and phone-free. No cameras. No $200 toothbrushes. No nonsense. Why Apple Watch users love it: • Tooth-by-Tooth Coaching: Custom zone pacing - get haptic cues every few seconds so no molar gets left behind. • Use Any Toothbrush: Electric, manual, bamboo stick from the eco aisle - Toothify doesn’t judge. Just strap on your Watch and go. • Hands-Free + Sink-Safe: No phone balancing acts. Just buzz-and-go with subtle wrist taps guiding your routine. • Adult UI, Zero Cartoons: Clean design, calming feedback. Because you’re not 7. (But your dentist will still be proud). • Apple Health Integration: Automatically logs your brushing streaks to Apple Health. Track trends, celebrate habits, and maybe even show off at your next check-up. • One-Time Purchase: No subscriptions. Just you, your Watch, and a slightly smug sense of oral superiority. Brushing twice a day is great. Brushing right twice a day? Even better.

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.
