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.

These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.

Hypothesis 1

Add interactive quizzes or gamified learning to engage users.

Assumption to check: Limited interactivity with elements, mainly static information.

Validate with people who use this workflow before building.

Hypothesis 2

Implement offline caching for element data.

Assumption to check: No offline access to data.

Validate with people who use this workflow before building.

Hypothesis 3

Allow users to customize themes and notification preferences.

Assumption to check: Lack of customizable user settings.

Validate with people who use this workflow before building.

Hypothesis 4

Enhance search with filters and advanced search options.

Assumption to check: Basic search functionality.

Validate with people who use this workflow before building.

App Store description

Atoms To Go is your go to source for chemical and nuclear data on the elements, much like a periodic table of the elements. In addition to the usual information found in such programs, it also contains a wealth of nuclear information on each isotope, including half life, decay mode, and daughter products. Data is displayed for the following physical properties: Density Heat of Vaporization Heat of Fusion Specific Heat Thermal Conductivity Linear Expansion Coefficient Melting Point Boiling Point Atomic Radius Covalent Radius Bulk, Shear, Young's Modulus Poisson Ratio Brinell, Mohs, and Vickers hardness data Magnetic Susceptibility Electrical Resistivity Electron Affinity Electric Dipole Polarizability State (gas, liquid, solid) Photoelectric Work Function Electronegativity Crystal Structure Abundance in Earth's Crust Abundance in Earth's Sea Abundance in Earth's Atmosphere Abundance in Solar System Number of Isotopes Number of Naturally Occuring Isotopes Number of Stable Isotopes Photon Interactions Magnetic Dipole Moment Electric Quadrupole Moment Nuclear Spin For each isotope, the following information is available: Decay mode Half life Abundance Atomic mass Mass excess Binding energy Q value Nuclear spin Magnetic moment Electric moment Alpha radiation energy Beta radiation energy Electron capture radiation energy Number of protons Number of neutrons Daughter produce Possible parent(s)

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.
