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.

OT Seasonal shows how a stock, ETF or index has behaved in every month and every week of the year, and what that history says about the weeks ahead. MONTHLY TABLE Twenty years of monthly moves in one colour-coded grid, with the minimum, maximum and average for each month and how often it closed higher. The months still ahead this year show their historical odds. WEEKLY TABLE Ten years of week-by-week moves with the average for each week of the year, so you can spot the strong and weak stretches of the calendar. CHART WITH SEASONAL RANGE Daily and weekly charts with the Trend indicator. A seasonal range box projects the coming week (on the daily chart) or month (on the weekly chart): the historical high and low, the average and a ±1σ band, drawn as price levels. AI ANALYZER (one-time in-app purchase) A clear, one-page Market Pulse for any symbol: - Market Snapshot: is the coming week and month seasonally positive or negative, how often it closed higher, and what the daily and weekly Trend indicator say - Levels to Watch: next week's and next month's ±1σ and full historical range as prices, plus options markers and dealer levels - Options Positioning: call and put open interest, max pain, gamma wall and flip, put wall, implied volatility and the expected move, also drawn on the chart - Seasonal Calendar for the next three months - NYSE and NASDAQ market breadth gauges - Share the result as an image Every number comes straight from the app's own data. It works on every device, with or without Apple Intelligence. DJIA HISTORY (one-time in-app purchase) Monthly and weekly seasonality for the Dow Jones Industrial Average going back to 1886. WATCHLISTS Keep your symbols in watchlists synced through iCloud and step through them with one tap. One price, no subscription. The AI Analyzer and DJIA History are optional one-time purchases. For information only; not investment advice. Seasonal averages describe the past and don't guarantee future results.

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.
