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.

Your map. Your model. Your election night. Build your predictions. Follow reported results. See how your picks stack up. US Election Simulator brings interactive maps, customizable forecasts, election research and historical results together on iPhone and iPad. Explore the battle for control—or build your own view of how it could unfold. ELECTION NIGHT LIVE Turn election night into an interactive experience. • Follow reported Senate, House and Governors results. • Explore maps, labeled seat views and individual races. • See the battle for control with TV presentation mode. • Check when polls close across all 50 states. • Draw on maps to highlight your analysis. • Share election map cards with others. COMPARE YOUR PICKS WITH THE RESULTS How good was your map? Save a prediction from the 2026 Senate, House or Governors screen, then select it in Election Night Live. Visually compare your picks with reported outcomes, track your accuracy as races are called, and share your prediction score. CREATE YOUR OWN FORECASTING MODEL Start with the in-house model—or make the assumptions your own. A guided, seven-step builder helps you create personal models for the 2026 Senate, House and Governors elections. Choose your signals, adjust the national environment, explore individual races and set the room for surprises. • Plain-language explanations help you understand each setting. • Adjust race estimates and candidate strength. • Review your assumptions before running. • Save, edit and share personal models. • Clearly see whether you are viewing the in-house model or your own. EXPLORE THE 2026 FORECASTS Look beyond who is ahead. • Race-level win probabilities and projected vote shares. • Candidate vote estimates, including supported independents. • Party control odds and projected seat totals. • Outcome distributions and uncertainty ranges. • Paths to a majority and the races with the most uncertainty. • Likely voter turnout estimates with optional display controls. CREATE, SAVE AND SHARE MAPS Explore scenarios for Senate, House, Governors, the Presidential Electoral College and presidential primaries. Change race assignments, track potential party flips, adjust labels, annotate maps and save named scenarios. Choose a patriotic background, use your own photo or turn the background off. Share map cards to explain your predictions. RESEARCH THE RACES Use Research Mode on the 2026 Senate, House and Governors maps to explore candidate information, available portraits, campaign links and related headlines. Zoom into states and House districts while keeping the map in view. DAILY SUMMARY AND DAILY ODDS Explore control odds, competitive races, presidential approval, generic-ballot trends and projections through graphical dashboards. Compare model forecasts with available market context and see refresh progress as information loads. ELECTION NIGHT WIDGETS Keep election information close at hand with widgets for iPhone and iPad. View supported updates and check when the information was last updated. EXPLORE ELECTION HISTORY Revisit supported presidential, Senate, House and Governors elections. Explore states, counties and congressional districts where available, with candidate totals, percentages and party results. Supported runoff races open with the final runoff results and let you switch back to the initial election. BUILT FOR IPHONE AND IPAD Use portrait and landscape layouts, zoomable maps, organized options, a graphical home screen and screen-specific help. For election enthusiasts, educators, students, journalists and anyone who wants to explore the possibilities. Models are simulations, not guarantees. Illustrative vote totals use historical turnout assumptions. News, candidate information, and results coverage vary by race and source.

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.
