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
SkyDroid - Golf GPS gives you your distance to every green on the course and more. Golf GPS that is easy to use, has a beautiful design, and there are no subscription, usage or course download fees. We have over 30,000 courses available, with new courses being added every day of the year. You can view the entire course list on our website: www.skydroid.net. Add new courses (if yours is missing) to our system using our web based Course Mapper tool (see skydroid.net for details and tutorial). Feel free to contact us with questions ([email protected]) Note: See our usage note below for help on searching for courses. FEATURES: • Clean and Clear design • Distances to the front, center and back of every green on the course • Distances to course features (water hazards, bunkers, target points) • Satellite image of every green and course • Shot Tracking: Track the distance of your drives! • Find your distance to ANY point on the course. • GPS Accuracy indicator (tap at anytime to find your exact accuracy) • Distances in yards or meters • Auto Hole advance • Works Internationally!! • Audio updates to the center of the green. A great hands-free way to use SkyDroid. • Book discounted tee times directly through SkyDroid. No other fees are involved, and you can download as many courses you want without any other charges. With SkyDroid – Golf GPS, our simple-to-use design will have you spending your time on your golf game, not on clicking buttons. View all our courses at www.skydroid.net/courses.php View our FAQ at www.skydroid.net/faq.php USAGE NOTES: • SEARCHING for Courses: When searching for courses by name, you can just search for "Aug" instead of "Augusta National Golf Course" (leave out the quote marks). • SEARCHING for Courses: Radar button will find Mapped courses within 25mi/40km of your current location. • To save battery power, click your power button to turn off the screen when not in use. • Set your GPS Keep Alive in the SkyDroid settings to control how long GPS stays active when SkyDroid is in the background. Continued use of GPS running in the background can dramatically decrease battery life. • GPS accuracy can vary over time (click the GPS signal strength icon at any time to see your accuracy). • Before playing a course preview its mapping by clicking the link for the course name at www.skydroid.net/courses.php (best done using a large screen). Let us know of any mapping issues, or make changes yourself. • If we don’t have your course, you can add it as long as there is a satellite image of the course available in Course Mapper. • Change distance measurement (yards/meters) in the app Settings available on the in-app Menu. • While playing golf you will only incur data usage while using the Satellite View screen. Course downloads can be done at home over Wi-Fi and are small in size. Enjoy your round!!

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.
