Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
Pass your electrician exam in any state, journeyman or master, with prep that feels like a game, not a textbook. Sparky is the study app built for electricians: smart drills, a skill tree mapped to the real exam blueprint, and streaks that keep you coming back every day. ALL 50 STATES Sparky offers study prep for all 50 states. Select your state and pass your journeyman or master electrician exam: Sparky automatically matches the NEC edition your state tests on, so every code reference lines up with your book. WHY IT WORKS • 1,087 practice questions mapped to the actual exam blueprint: calculations, NEC code lookup, theory, and safety • Smart Review: 10-question mixed drills that automatically target your weak spots • Practice hints: stuck on a question? Tap Hint to get the formula, or the exact NEC section to look up (practice mode only, never in the timed exam) • 33-subtopic skill tree: level up across every section of the exam • Timed full-length practice exam that simulates test day • NEC formula sheets (2017–2026 editions) built right in • Streaks, XP, and daily goals that make consistency automatic BUILT FOR REAL EXAMS Whether you're going for your journeyman license or leveling up to master, Sparky trains the skill the exam actually tests: finding answers in the NEC codebook fast, under time pressure. Every question builds codebook fluency, not memorization. START FREE Try a free 10-question Smart Review, no signup needed.

Opportunities
AI-GENERATED OPPORTUNITY HYPOTHESES
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.
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.
