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

The DST (Dementia Screening Test) is the only dementia test which is a medical device as per regulatory requirements. The DST very effectively detects early dementia risks, and can reliably distinguish between the different dementia risk levels. It is therefore suitable for dementia screening, as well as for risk severity monitoring / therapy control over time. Additional functions include: - a reminder to redo the test after 3-6 months, for medical monitoring - continued engagement for prevention, through regular Dementia News - tracking of the dementia risk over time, visualized in a graphic - option to e-mail and/or print the test results (e.g., for documentation purposes) To date, there is no effective treatment for advanced dementia stages. Therefore, effective screening is essential to begin treatment before the brain damages become irreversible. Because for early dementia stages, there are already effective treatment options that can significantly delay or even prevent disease progression. With special tests, dementia risks can be detected 18 years and more prior to the first symptoms. The Dementia Screening Test (DST) is the only such test which is a Medical Device for dementia screening as per the regulatory requirements. The good news is: for most people the test can give the all-clear! The DST in short: - Easy to perform, also for medical laypersons. - Reliable: more than 96% sensitivity of the algorithm shown in clinical trials, probably the highest value worldwide for such tests. - Safe: no registration required, no storage of personal data, works without internet connection, no advertising. - Medical Device as per regulatory requirements. - Works with all dementia subtypes (Alzheimer's dementia, vascular dementia, fronto-temporal dementia, Lewy-body dementia, secondary dementia, hybrids / other forms). - Engaging: provides you with the latest research results on a regular basis, and reminds to retake the test regularly. - Documents changes in dementia risk over time. - Supports research and public awareness for dementia patients and relatives. The DST as such, like any medical test, does not provide or replace a diagnosis. Therefore, please seek a doctor’s advice in addition to using this app and before making any medical decisions. Take the test now, and become a superager!

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.
