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

Whisper Notes turns meetings, lectures, interviews and voice memos into accurate text with speaker labels, 100% offline on your iPhone and iPad. One-time purchase, no subscription. Trusted by 70,000+ journalists, researchers and professionals. ■ Record and import - Record from the Lock Screen, widgets, Control Center, the Action button, Apple Watch, or "Hey Siri". - Import from WhatsApp, Voice Memos, Photos or Files, several at once. ■ Transcribe - 101 languages through Whisper, detected automatically, even when speakers mix languages. - Choose your on-device model: Parakeet, Whisper (OpenAI's open-source model) or SenseVoice, plus Apple Speech on supported devices with iOS 26. - Speaker labels (speaker diarization) show who said what. Rename each speaker. ■ Edit and export - Double-tap any paragraph to fix a word. - Export TXT, Markdown or SRT subtitles with timestamps and speaker labels. Works for videos too. - Auto-save every new transcript to Files or iCloud Drive. ■ Private by design Your audio never leaves your device. Turn on airplane mode and Whisper Notes works exactly the same, which matters when the recording is an interview, a client meeting, or anything you wouldn't put on someone else's server. ■ One-time purchase No subscription, no in-app purchases, no ads. Not satisfied? Settings → Request Refund. ■ Quick answers Does Whisper Notes work completely offline? Yes. It transcribes on your iPhone or iPad, so it works in airplane mode. The built-in Parakeet model covers 25 European languages offline from the first launch; for other languages, download Whisper or SenseVoice once in the app. Can it transcribe WhatsApp voice messages? Yes. Share a voice message to Whisper Notes and it is transcribed offline. Does it identify speakers? Yes. Tap ⋯ on a note → Detect Speakers, and each passage is labeled by speaker. Which model is best for Chinese, Japanese or Korean? SenseVoice, built for Chinese, Japanese, Korean and Cantonese. Is there a time limit? Each recording can be up to 24 hours long. Which iPhones are supported? Whisper Notes needs iPhone 12 or newer. Your notes live only on your device, so deleting the app deletes them. Export what matters. Questions?

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 advanced natural language processing to improve accuracy

Assumption to check: Inaccuracy in speech recognition

Validate with people who use this workflow before building.

Hypothesis 2

Add more languages and dialects for transcription

Assumption to check: Limited language support

Validate with people who use this workflow before building.

Hypothesis 3

Simplify and streamline the note management experience

Assumption to check: Cluttered interface for managing notes

Validate with people who use this workflow before building.

Hypothesis 4

Enable offline note-taking and storage capabilities

Assumption to check: Lack of offline functionality

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.

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.
