Evidence scope: No current overall US chart position is available. Category-chart positions shown in discovery are a separate scope. Revenue is a directional model estimate, not verified earnings.
A product spec, screen plans, and build steps for your coding agent.

Combine features and design from your favorite apps.
Your first Build Kit is free with a verified email.
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.

SkyBrief — Preflight Weather Briefings for Pilots Honest, complete weather briefings you can trust before every flight. SkyBrief turns raw METAR, TAF, TFR and NOTAM data into a clear go/no-go picture — with no invented values and no guesswork. When a data source is unavailable, SkyBrief tells you plainly instead of filling the gap with made-up numbers. FREE • Live METAR & TAF for any U.S. airport, decoded into plain language • Automatic VFR / MVFR / IFR / LIFR flight category and a go/no-go read • NOTAM digest — active notices grouped by type, closures and restrictions first • Nearby stations, airport directory, and a 24-hour conditions trend • Weight & balance calculator with CG envelope • Flight logbook, currency tracker, and custom checklists • Home Screen widget — your home airport's conditions at a glance • Shareable briefing cards PRO • AI-powered plain-language briefings, with voice read-aloud • Route briefings with real FAA TFRs and true terrain profiles • Winds-aloft nav log and a best-altitude optimizer (compare time & fuel by altitude) • Live radar & satellite overlay on your route • Personal-minimums monitoring with optional push alerts • Kneeboard flight mode, W&B what-if scenarios, and PDF briefing export • Cloud-synced briefing history BUILT ON HONEST DATA Your decisions deserve honest inputs. SkyBrief shows real observations and forecasts from aviationweather.gov and the FAA — and is transparent whenever data is missing or a scan can't complete. ACCESSIBLE Full in-app text-size scaling and high-contrast, readable text in every lighting and sky condition. SkyBrief is a decision-support tool and is not a substitute for an official FAA weather briefing. Always obtain an official briefing before flight.

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.
Not assessed in a Build Kit yet.
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.
