Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Sherlock is a reverse image search for faces. Add a photo of yourself and see where that photo appears across publicly available sources on the web — the same idea as a reverse-image search, applied to a face. WHAT YOU CAN DO • See where your photo appears online — social posts, blogs, news, and other public pages. • Spot stolen or reused pictures of you. • Find accounts that use your photos to impersonate you, so you can report them. • Check your own public image footprint. HOW IT WORKS 1. Add a clear photo of yourself. 2. We run a visual-similarity (reverse image) search across public web sources through our search provider. 3. You get a list of matching images and the source pages where they appear, ranked by visual similarity. WHAT SHERLOCK IS NOT Sherlock does not build, store, or maintain any profile, dossier, or database of any person. It does not identify people, reveal names, or compile personal information. Every search returns only image matches and their public source links — nothing more — and results are never saved. PRIVATE BY DESIGN • We don't store the photos you search. • Your photo is sent only to our third-party search provider (FaceCheck.ID), with your explicit in-app consent, solely to run the search — and is deleted by the provider within 24 hours. • No ads in the app. Advertising attribution is used only as described in our Privacy Policy and follows your iOS tracking choice. RESPONSIBLE USE You must be 18+. Search only your own face, or a photo you have explicit permission to search. Do not use Sherlock to identify, profile, monitor, harass, or stalk anyone, to upload photos of minors, or for employment, housing, credit, insurance, or other FCRA-covered decisions. Results are based on visual similarity, can be incomplete or inaccurate, and never confirm anyone's identity. Subscriptions auto-renew until cancelled; manage anytime in your Apple settings.

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.

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.
