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
Save every place you find on TikTok, Instagram and Google Maps to one map you'll actually use. You screenshot the restaurant. You save the Reels. You paste the address into your notes. Then the trip comes around and it's all gone. Step fixes that. Share a post to Step and the places land on your map, tagged and sorted by city, waiting for you when you get there. IMPORT FROM ANYWHERE TikTok. Instagram posts and Reels. Google Maps links. Screenshots. Even the running list in your Notes app. Send it to Step and we pull the place, the address and the details. No copy-pasting, nothing lost. BUILT AROUND CITIES Your saves organise themselves by city automatically. Land in Lisbon, open Step, see every place you've been collecting for months. RECOMMENDATIONS FROM PEOPLE, NOT ALGORITHMS Follow friends and Step's Culture Curators, a network of writers, chefs, designers and travellers who publish guides to the cities they know best. Build a personally curated map of the world, populated by the people you love, respect, and admire. MADE TO BE LOOKED AT Step is designed like a magazine, not a directory. Clean typography, real editorial, none of the review-farm noise. WHAT PEOPLE USE STEP FOR - Collecting places from social media before a trip - Rescuing a years-old list of recommendations out of Notes - Keeping a running map of their own city - Sharing a list of recommendations with a friend in one link - Following creators they trust instead of trawling review sites Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Hypothesis 1
Expand partnerships with local providers for a broader range of activities.
Assumption to check: Limited activity options in certain destinations
Validate with people who use this workflow before building.
Hypothesis 2
Implement a more robust review verification system.
Assumption to check: Inconsistent user reviews and ratings
Validate with people who use this workflow before building.
Hypothesis 3
Simplify navigation and categorize activities more effectively.

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
Expert
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.
