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
Sweet Spot is the drip counter for PuckPuck cold brew, and any cold dripper. Tap along with every drop and it reads your drips-per-minute in real time, so you can dial in the slow, even rate that makes cold drip taste sweet instead of sour. A one-time 99c purchase. No account, no subscription, no tracking. Built for the PuckPuck cold-drip adapter on your AeroPress, and just as happy with a Kyoto-style tower or any slow dripper. Cold drip is simple but fussy, and the whole cup rides on the drip rate. Too fast and it comes out thin and sharp; too slow and it stalls. Sweet Spot gives you a steady read on that rate and tells you the moment you have found the sweet spot. TAP EACH DROP Tap the big circle on every drop you see. Sweet Spot works out your rate from the rhythm, scores how steady your hand is, and reacts in plain language: SLOW, WHOA, or BANG when you land it. YOUR SWEET SPOT Set the target range you are aiming for with a simple slider and see the brew time it works out to. Sweet Spot remembers your range for next time. TWO BREW GUIDES PuckPuck (the cold-drip adapter for your AeroPress) and a dedicated cold-drip tower are different rigs, so each gets its own recipe and steps: dose, grind, water, ice, drip rate, and time. A SHORT LIST OF NEVERS No account or sign-in. No subscription. Bought once, yours for good. No ads, no tracking, no nudges. Tap along, walk away, and come back to a sweeter cup. Bonus points for a dehydrated orange wheel.

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.
