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.

Now with integrated Facebook & Twitter sharing! "Good radiation prank app!! ***** Worth to buy!" - Radin Fikri (Malaysia App Store) "Awesome! ***** Can't wait to try this in different parts of the world to "prove" that some places have more natural radiation than an exploded power plant!" - Erich Meatleg (US App Store) "Good App...Nice to fool people with!" - austinmu_ (US App Store) "It's great! My friend thought it was totally real." "...had a lot of fun with it...convince your 16-year old son that he must have stood in something radioactive because his sneakers make the count rate zoom up" - EE Times review "Rad u ***** Now I can prove to everyone that they are indeed radioactive. And i can refuse to give rides to deadbeats at work if the geiger counter detects radiation on their shoes." - Callagene (Canada App Store "***** Eccellente" - Lucasteno (Italy App Store) "Valutazione **** Semplice ed ottimo strumento di rilevazione Buono" - Ermanred (Italy App Store) FEATURES • easy-to-read LCD display measures spurious hazards from background to extreme levels • oversized numeric meter easily switchable from microsieverts to millirem or count per minute scales • realistic digital counter from 0.10 μSv/h to 100 μSv/h (0.01 mrem/h to 10 mrem/h) • authentic audio click rate, easily mutable for library or classroom use • versatile alpha, beta, and gamma modes • dual tilt-sensitive and touch-sensitive controls • audio synchronized iPhone camera flash adds to the tension INSTRUCTIONS 1. Hold Digital Geiger Counter flat and face up. 2. Smoothly tilt Digital Geiger Counter's face to the left or right on the x-axis to increase levels. 3. Surreptitiously touch and hold the yellowish radiation symbol on the bottom left of the screen with your thumb to boost levels if necessary. The outside circle edge gives minimal boost, slowly increasing to maximum boost in the bottom left hand corner of the screen. 4. For best results with Digital Geiger Counter, practice subtly combining both tilt and touch control methods. Also try twisting Digital Geiger Counter as you move it towards your target. Be slow and smooth. WARNING Digital Geiger Counter is meant for entertainment purposes only and is entirely ineffective at detecting actual ionizing radiation. Digital Geiger Counter is factory-calibrated to the x-axis and contains no user-serviceable parts.

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.
