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

Twenty-five evidence-based clinical calculators for neonatal intensive care, designed for the bedside. Built by an Australian neonatal clinician for fellow NICU professionals. CALCULATORS INCLUDED Respiratory & Physiology • Alveolar-arterial O₂ gradient • Altitude physiology • Base excess • Low-flow O₂ delivery • Mean airway pressure • Nitric oxide delivery • Oxygenation index (with ECMO threshold alert) Fluids & Nutrition • Dextrose infusion preparation • Glucose infusion rate (GIR) • Fluid & feeds rate Survival & Outcomes • Extreme preterm outcomes • Diaphragmatic hernia survival probability • ECMO risk in diaphragmatic hernia Resuscitation & Procedures • Apgar clock & CPR metronome • ET tubes & umbilical catheters • Partial exchange transfusion (polycythaemia) • Percutaneous long lines Gestation Calculators • Corrected gestational age • Gestational age at birth Converters & Measurements • Weight converter • Bilirubin units (μmol/L ↔ mg/dL) • Glucose units (mmol/L ↔ mg/dL) • Pressure units (kPa ↔ mmHg) • Body surface area • Percentage weight loss DESIGNED FOR THE BEDSIDE • Works offline — no data leaves your device, ever • iPad-adaptive layout shows sidebar + calculator side by side • System-wide search via Spotlight • Haptic feedback on clinical warnings • Dark mode and pressure-unit preferences sync across all calculators • In-app Algorithm and References dialogs explain the maths and cite primary sources where applicable CLINICAL DECISION SUPPORT ONLY Nicutools is a reference tool for qualified healthcare professionals. All calculations must be independently verified against your local protocols and your patient's circumstances. Not a substitute for clinical judgement. The free web version is at nicutools.org. This iOS app adds native iOS conveniences — Spotlight search, iPad split-view, haptics, true offline support, and no analytics.

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.
