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.

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.
Hypothesis 1
Implement real-time traffic overlays and alerts.
Assumption to check: Navigation apps often struggle with real-time traffic updates
Validate with people who use this workflow before building.
Hypothesis 2
Provide offline maps for downloaded trails.
Assumption to check: Users face issues with offline map availability
Validate with people who use this workflow before building.
Hypothesis 3
Enhance voice navigation with better TTS and lane guidance.
Assumption to check: Voice navigation can be unclear or inaccurate
Validate with people who use this workflow before building.
Hypothesis 4
Include a recommendation feature based on user preferences.
Assumption to check: Limited discovery of nearby trails
Validate with people who use this workflow before building.

App Store description
Off trail. In the brush. Still know the way back. You’re bushwhacking for that next spot, ducking under branches and pushing through undergrowth. No clear path—just you and the woods. When you’re deep in and the canopy’s thick, “which way did I come from?” gets real. ShroomLoop keeps your route on the map so you can wander without the worry. One tap starts tracking. Your path shows as a line—every detour, every crawl, every spot you checked. Share it with someone in a tap so they know where you are. When you’re ready to get out, turn on Follow Back and the map guides you along your own breadcrumb line to the start. Drop pins and photos at your finds; they’re saved with the route. Pull up any past day to see the full path and your spots again. Compass and reverse compass are there when you need to reorient in the thick stuff. ShroomLoop is for going off trail and coming back—route tracking for when the only path is the one you’re making.

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.
