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

Know exactly what your overtime is worth, before the check arrives. Overtime Tracker turns every extra hour into a clear picture of your earnings. Start the timer when you begin OT, and watch your net pay climb in real time — right on your Lock Screen and Dynamic Island. No more guessing what that extra shift was worth. REAL-TIME EARNINGS TRACKER Built around a simple start/stop timer that calculates your net and gross pay down to the second. Your personalized rate is calculated from your actual pay stub, so the numbers you see are the numbers you take home. LIVE ACTIVITIES & DYNAMIC ISLAND See your earnings update live on your Lock Screen and Dynamic Island while you work. No need to open the app — your overtime pay is always visible at a glance. PAY STUB IMPORT Scan or photograph your pay stub and the app extracts your gross pay, net pay, and hours automatically. Works with Cal Employee Connect and other pay stub formats. Your exact net and gross hourly rates are calculated for you — including your effective tax rate. BILLS & GOALS Assign your overtime earnings before they arrive. Add bills like rent or a car payment, and savings goals like a vacation or new purchase. The app funds bills first in your priority order, then allocates the rest toward goals. Drag to reorder priorities anytime. Unfulfilled bills and goals automatically roll over to the next pay period — only the remaining balance carries forward, since the funded portion is assumed paid from that check. CTO TRACKING Track Compensatory Time Off alongside cash overtime. Log CTO hours, set a target balance, and watch your time bank grow across pay periods. Choose between Cash or CTO every time you start a session. PAY PERIOD CALENDAR Sessions are automatically organized into pay periods. See days remaining in the current period, your next pay date, total hours, and a full breakdown of earnings — all in one place. GUIDED SETUP A friendly onboarding walks you through importing your pay stub, setting your CTO balance, and creating your first bills and goals. You'll be fully set up in under two minutes. ALL YOUR STATS View all-time totals for net earnings, gross earnings, total OT hours, and CTO hours accumulated. Track your progress period by period or across your entire history. PRIVATE & OFFLINE All data stays on your device. No accounts, no servers, no tracking. Your pay information never leaves your phone.

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.
