Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
Welcome. We hope Acuhealer gives you the quiet nights you deserve, away from that irritating tinnitus. After trying all of the apps out there, we decided to build one ourselves that's the simplest, most affordable, and useful that makes you actually use it and get some good sleep masking that annoying tinnitus with it. Enjoy some engineered sounds that mask tinnitus. Acuhealer is the simplest app for covering the ringing in your ears and falling asleep in peace. Pick Hush, Pure, or Drift, hit play, and let the ringing fade into the background. Set the timer, put your phone on the nightstand, and the app turns itself off while you sleep. No subscriptions, no accounts, no ads. One-time purchase, yours forever. THREE SOUNDS, ENGINEERED FOR TINNITUS • Hush — soft static sound we designed that covers the ringing without tiring your ears. • Pure — a clean tone adjustable to 1, 4, or 8 kHz so you can match it to the exact pitch of your tinnitus. • Drift — a warm pink-noise-style flow sound we designed, ideal for falling asleep. Try all three and keep the one that helps you most. BUILT FOR SLEEP Acuhealer understands how you sleep when your ears won't stop ringing. The timer fades the audio out and releases the screen so it can turn itself off. No jolt awake to a tone cut short in the middle of the night. Playback keeps going even when your phone is locked. ONE-TIME PURCHASE Pay once, relief forever. Zero subscriptions, zero in-app purchases, zero accounts to create. What you pay is what you get. HONEST BY DESIGN Acuhealer is not a medical device and does not cure tinnitus. It's a sound-masking tool that many people use to rest better while living with the ringing. If your symptoms are new or getting worse, see your audiologist or ENT. WHO IT'S FOR • You, if the ringing in your ears keeps you up at night. • Anyone who wants a simple app — no subscriptions, no personal data. • Anyone who prefers to set the phone down and let the app do its quiet work. Welcome. We hope Acuhealer gives you the quiet nights you deserve. Privacy policy: https://acuhealer-mobile.replit.app/privacy Terms of use: https://acuhealer-mobile.replit.app/terms

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
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.
