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

A quick and simple way to calculate a number of common grazing related equations used by dairy and beef farmers. This app is the brainchild of a dairy farmer, who wanted a fast and easy way for him and his workers to be able to do grazing related calculations, and was designed and developed in collaboration with his sister, with input from other farmers and farm advisors. Designed to be used out on the farm and on the go, this app makes it quick, easy and simple for anyone working on a dairy or beef farm - regardless of their level of experience and knowledge - to get the numbers they need, when they need them. About the calculators (visit our website for more detailed descriptions): ● Days in Paddock - Work out the approximate number of days to leave a specific number of cows in a paddock using either: ◦ kgDM/cow or lbDM/cow allocation, paddock size, cover and residual. ◦ m2/cow/day or yd2/cow/day allocation and paddock size - These results can then be used to calculate approximately where to put the break fence in a paddock. ● DM/Cow/Day - Work out approximately how many kgDM/cow/day or lbDM/cow/day you will get from a paddock based on paddock size, cover, residual, number of cows and number of days. - This result can then be used to calculate approximately where to put the break fence in a paddock ● Crop Allocation - Work out the approximate area of crop to allocate and the approximate number of days you can leave the cows in a paddock based on yield, the number of cows, the kgDM/cow/day or lbDM/cow/day required and paddock area. - This result can then be used to calculate approximately where to put the break fence in a paddock ● Pre-Grazing Cover - Work out the approximate target pre-grazing cover or the paddock trigger level based on stocking rate, intake, round length or rotation and the optimum residual. ● Average Pasture Cover - Work out the approximate average pasture cover for your farm based the pre-grazing cover and optimum residual. Enter the values directly or use the result from the Pre-Grazing Cover calculator. Other Features: ● Choose to do the calculations in Metric or US system of measurement. On first installing the app will be promoted to choose from using either the Metric or US system of measurement. You can change the selected units at any time via the Settings. ● Share the result of the calculation using any of the available options off your device. ● Settings options for the shared content: - send answer only, or send the answer and variables - include or don't include units - always edit before sending, never edit or choose each time whether edit or not ● Add a note after completing the calculation e.g. paddock or mob name. This note will be included in the shared content. ———————————————————————— Thanks to everyone who has given feedback and suggestions! It has been very useful in helping us improve the app. We are always looking for ways to make the app better, so please contact us if you have any feedback or suggestions.

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.
