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
Swing, flip and twist through a physics playground built for calisthenics, gymnastics, parkour and freerunning moves. Noomi is a ragdoll gymnast you control one move at a time. Tuck, pike, arch or lay out in mid-air, add twists, let go of the bar and catch the next one. It's all real physics: momentum and spin carry through every move, so no two runs play out the same. FEATURES • 18 maps: 12 bar maps, from Classic and Trampoline to City and Workout Park, plus 6 tumbling maps with boxes, ramps, platforms and moving blocks • Moves: tuck, pike, arch, layout, squat, twists both ways, flash kicks, stuck landings and bar regrabs • Slow motion to nail your timing • Replays: scrub through your best runs and save them to Photos as videos, with your taps shown on screen if you like • Make the controls yours: move and resize every button • Unlock skins with regrabs, or buy them with NoomiCoins • Back up your progress with an optional sign-in • Play in 17 languages Made by a solo developer in Unity.

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.
Hypothesis 1
Add more diverse game types and regular updates.
Assumption to check: Limited variety of mini-games
Validate with people who use this workflow before building.
Hypothesis 2
Implement friend invites, chat features, and challenges.
Assumption to check: Lack of social features
Validate with people who use this workflow before building.
Hypothesis 3
Focus on rigorous testing and quality assurance.
Assumption to check: Occasional bugs during gameplay
Validate with people who use this workflow before building.
Hypothesis 4
Implement a more user-friendly ad system, like rewarded ads or fewer interruptions.
Assumption to check: Ads interrupt gameplay
Validate with people who use this workflow before building.
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.

BUILD KIT DIFFICULTY
Intermediate
From the Build Kit assessment.
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.
