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

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

“Awesome!!! The best speed app on iphone” 5 Stars by kurtonic Speed Box is a Speedometer and GPS app for both your iPhone and iPad. It displays your current speed, distance, direction and altitude along with your top speed and average speed. The app also keeps a record of the speed and altitude for the last few hours. Now including trip logging to log location, speed and more data for individual trips! MAIN FEATURES ======================== * MPH, KM/H and KNOTS * Show decimal speed (e.g. "45.7 mph") * One app for both the iPhone and iPad * "Speak speed" - Tap screen to have the speed spoken to you * 11 Analog and digital speedometers * Map view * Maximum and average speed * Altitude * Digital compass * HUD display to see speed in windshield * Odometer to measure distance traveled * Chart of the traveled speed and altitude * Warning signal when driving too fast * Export last 3 hours of data * Change maximum displayed speed on speedometer * Swipe finger over chart to display historic data * Display GPS accuracy by tapping the indicator in the top left corner USER REVIEWS ======================== 5 Stars by Darekakuta "Just what I needed. My '58 chev's speedo doesn't work. This did the trick." 5 Stars by Rawd "Great My 79 Firebird speedo only goes to 140 kmh. ;). This worked perfectly." 5 Stars "Within 1 mile per hour +/- Great Job!" SpeedBox was one of the very early Speedometer Apps for the iPhone. Take advantage of my experience and the refined algorithms that can get a much greater accuracy from the iPhone then a lot of other apps. I regularly update my application to make it even more accurate and usable. Users have already used our application to verify the accuracy of their car's speedometer or they tried measuring the speed they achieved while skiing. Can you come up with more ideas? How about measuring the speed of the airplane you travel with? USAGE NOTES ======================== The "GPS strength" indicator in the top left corner should display a green dot. You can tap this indicator to display the current GPS accuracy. Please allow the application up to a minute to find enough satellites to work correctly. If you get a message to enable GSP, please go to ”Settings > General > Location Services“ on your iPhone and check if the little switch is set to "On" for Speed Box as well as for "Location Services" in general. ATTENTION iPod touch users! Unfortunately this app doesn't work very well on the iPod touch and the iPad WiFI (without 3G) since these devices are missing a GPS! FEEDBACK ======================== If you've got any wishes or suggestions for new features, please let me know with the contact form on this application's website (see link below). I am already working on the next update!

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.

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.
