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.

Make better frozen drinks with human-created recipes, smart calculators, and mix-fixing tools built for home slush machines. SlushIQ is a slush machine calculator and recipe app that helps you make smoother slushies, frozen cocktails, mocktails, frozen coffee drinks, milkshakes, frappes, and party batches. Using Brix and ABV calculations, SlushIQ helps balance sugar, water, alcohol, and total batch size for a better frozen texture. Browse recipes designed for home frozen-drink machines, save your favorites, build custom recipes, scale batches, or get guided help when a mixture is too icy, too soft, or will not freeze. Features: • Recipe Library – Browse human-created frozen drink recipes designed for home slush machines. Recipes are not AI-generated. • My Library – Save favorite recipes and keep your custom creations together • Batch Scaling – Resize recipes for 48 oz, 64 oz, 74 oz, 96 oz, and 112 oz batches • SimpleLAB – Use the nutrition label from a store-bought mixer to calculate the mixer, water, and optional liquor needed • DesignLAB – Build custom recipes with live volume, Brix, and ABV estimates • Auto-Balance – Get sugar or water suggestions to help bring a custom recipe into a slush-ready range • Brixley – Use AI-powered guided help to troubleshoot a batch and review possible adjustments • Offline Access – Reopen saved recipes when the online recipe library is unavailable • Home Machine Support – Built for popular countertop frozen-drink and slushie machines • No Subscription Fees – Download SlushIQ and use its features without an ongoing subscription Whether your mixture is too soft, too icy, too sweet, or will not freeze, SlushIQ gives you a smarter way to adjust the complete batch before wasting more ingredients. SlushIQ is an independent app and is not affiliated with or endorsed by Ninja, SharkNinja, Iceman, or other frozen-drink machine manufacturers. Brand names are used only to describe compatibility.

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.
