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

In today's hectic life it seems that everybody is living by the count of each minute. But do you really need such exact times as 3:03 p.m. or 10:39 a.m. in your everyday life? Wouldn’t ‘just after three’ be entirely sufficient? And 14:54 and 15:12 seem very different while it’s not. It makes you think too much about something that is fluid and paced and pushed along the same speed always: time.  Lucas’ Clock in short: # Clock without minute hand # Clean, minimal interface, easy to read at a glance from a distance # Tap to show minute hand for precise time reading (slowly disappears after 15 seconds, unless you tap again to make it disappear immediately) # Works on all orientations and screen sizes # No settings, No ads, No alarm # 4 different colors included (swipe left or right to change) This app makes time more real. Don’t think this is not precise enough, it takes a little getting used to. Ultimately your sense and estimation of time will improve. Perceiving time in this way comes actually from a historical perspective. Until the late eighteenth century tower clocks only had one hand, which showed the full hour. In fact, while measuring time was already important, the pace of life was definitely less frenetic compared to nowadays. Moreover, clocks had to be readable in the distance. With just one hand there was no risk to mix up hours and minute. This app follows just this design principle: it makes it easy to read at a glance from a distance. My grandfather Lucas made a beautiful clock. His clock was decorated with stars and the sun and only had one hand to indicate the hours. It inspired me to share this clock with you. Enjoy!

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.
