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
Sikum brings two Hebrew audio workflows into one private workspace: turn speech into editable text, and turn text or documents into speech. SPEECH TO TEXT Record a conversation, meeting, lecture, interview, lesson, or idea—or import an existing audio file. Sikum transcribes Hebrew directly on your device, with optional speaker identification, timestamps, speaker renaming, and full transcript editing. TEXT TO SPEECH Paste text or import PDF, DOCX, and TXT documents. Review and edit the extracted text, choose between the bundled Noga and Ari voices, then generate audio locally. Pause or resume generation, listen with playback controls, and export the result in M4A, WAV, CAF, or AIFF. ONE ORGANIZED LIBRARY Keep transcriptions and narrations together. Search titles and content, add labels, mark favorites, edit your work, delete items, and share or export only when you choose. BUILT FOR IPHONE AND IPAD Use the focused phone experience or an adaptive two-column iPad workspace that keeps your library and selected content side by side. PRIVATE BY DESIGN There is no account and no server processing. Speech recognition, speaker processing, pronunciation, and speech generation use models bundled with the app. Your recordings, imported documents, pasted text, transcripts, generated speech, and labels remain on your device unless you deliberately export or share them. Works without an internet connection after installation. Hebrew and mixed Hebrew/English text are supported for narration.

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 a feedback system to improve recognition over time.
Assumption to check: Voice recognition accuracy can vary based on pronunciation
Validate with people who use this workflow before building.
Hypothesis 2
Add categorization and tagging features for summaries.
Assumption to check: Users may lose track of summaries if not organized
Validate with people who use this workflow before building.
Hypothesis 3
Include more formatting options for text input.
Assumption to check: Limited text input options may frustrate users
Validate with people who use this workflow before building.
Hypothesis 4
Introduce cloud storage features for user data.
Assumption to check: No cloud sync or backup options
Validate with people who use this workflow before building.
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.
