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

With Unit Price Calculator you can easily choose the most economical package size. Calculator calculates unit price, shows the better offer and how much you can save. Need to know the product price per unit, weight, volume, length or area? Not sure you are getting the best deal? For example, is it better to buy eight 5-oz items for $9.50 or twelve 4-oz items for $12.50? With unit price calculator you can easily calculate the unit price. The unit price calculator lets you compare unit prices for similar products measured by weight, volume and products sold by the item: - price per unit (piece, package, etc) - price per weight (price per oz, lb, kg, 100 g, gram) - price per volume (price per fl oz (US), gal (US), fl oz imp, gal imp, ml, cl, dl, liter) - price per length (price per in(′), ft(″), yd, mm, cm, dm, meter) - price per area (price per sq in, sq ft, sq yd, sq, mm², cm², dm², m²) Simply enter the prices, quantities and sizes for comparable products and tap Calculate. To calculate the price with the Sales Tax, just set it in the Settings window. Unit Price Calculator shows you the better deal and your savings. With Unit Price Calculator you can even calculate how much you can save per month or per year choosing the more economical package size. For example, if you know your average consumption of sugar, water, apples, meat, milk, etc per week, month or year, just enter it in the "Calculate price for" and the app shows you how much you can save. You can enter any amount of units, ounces, pounds, liters, gallons, etc. you want to calculate the price for. For example, you can select to calculate the price per 1 fl oz, 5 lbs, 10 gal, 100 kg, 3 cl, etc. If you leave the field empty, the price will be calculated per one unit of measurement. You can compare products in US, imperial and metric unit measurement systems. Unit price calculator allows you to compare sale prices with or without discounts. You can enter discount percentage or discount amount. Note: to enter discounts, you need to rotate your device to landscape orientation. The app supports rounding to the specified number of decimal places from 0 to 3. By default, the app displays 2 decimal places. To round results to the nearest whole number, select 0 decimal places. Unit Price Calculator makes calculations in one of 21 supported currencies. Unit Price Calculator keeps calculation history so you can easily view and compare your recent calculations. You can easily share your results via email. The calculator supports both portrait and landscape orientation.

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.
