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.

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
Implement a review system for guides to build credibility.
Assumption to check: Lack of user reviews and ratings can make it hard for users to trust the content.
Validate with people who use this workflow before building.
Hypothesis 2
Add features like in-app messaging or community forums.
Assumption to check: Limited features may lead to user disengagement.
Validate with people who use this workflow before building.
Hypothesis 3
Enhance navigation with clearer labels and tooltips.
Assumption to check: Navigation could be confusing without clear labels.
Validate with people who use this workflow before building.
Hypothesis 4
Consider a freemium model with additional features for premium users.
Assumption to check: Single payment model may limit user acquisition.
Validate with people who use this workflow before building.

App Store description
Stop guessing. Start leveling. CamperLeveling turns your iPhone into a precision leveling tool for your campervan or motorhome. Place your phone in the vehicle, and the app instantly reads the tilt sensors to tell you exactly how many centimeters — or your preferred unit — each wheel needs to come up. No bubble levels, no guesswork, no getting in and out to check. Features: - Per-wheel leveling values — see the exact height adjustment needed at each corner, front and back - Live pitch & roll display — longitudinal and lateral tilt shown at a glance - Audio guidance — beeps speed up as you approach level, so you can focus on driving onto the chocks instead of watching your phone - Apple Watch support — mirror all values on your wrist while you move around the vehicle - Compass & altitude — always know your heading and elevation at camp - Sensor calibration — correct for your phone's mounting position or case - Customizable settings — set your wheelbase, wheeltrack, and preferred unit once and forget it

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.

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.
