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

Maybe the best offline transcription app — 70,000+ journalists, researchers, and professionals seem to think so. Turn meetings, lectures, and voice memos into accurate text with speaker labels — fast, 100% offline, on your device. No subscription. One purchase, yours forever. ■ Core Features - Record voice memos and capture ideas instantly—from the Lock Screen, widgets, Action Button, or just say "Hey Siri" - Import audio and video from any app (WhatsApp, Photos, Voice Memos, etc.)—even extract subtitles - Turn meetings, lectures, and interviews into transcripts with speaker labels—see who said what, rename speakers, no length limits - 101 languages, auto-detected (optimized for English)—three models (Parakeet, Whisper, SenseVoice), switch freely - Export as SRT, VTT, or TXT—timestamps and speaker labels included ■ Privacy & Speed Because everything runs on your device, there is nothing to upload—and nothing to leak. Turn on airplane mode before you record and leave it on: Whisper Notes works exactly the same. That matters when the recording is an interview, a client meeting, or something you would never put on someone else's server. Transcribing 5 minutes of audio on iPhone 15: ~18 seconds with Parakeet, ~1 minute with Whisper. SenseVoice is much faster than Whisper and strongest for Chinese, Japanese, and Korean. Each model has its strengths—choose freely based on language and use case. Older devices are slower but work fine. ■ Honest Pricing Because transcription runs on your device, we have no server costs—so there is nothing to charge you monthly for. Most similar apps charge $100+/year; we charge once. No subscriptions, no in-app purchases, no ads. Not satisfied? Tap Settings → Request Refund. ■ Common Questions Does it work completely offline? Yes. Your audio never leaves your device. Works on flights, in remote areas, anywhere. Can I transcribe WhatsApp voice messages or videos? Yes. Share or save audio/video from WhatsApp to Whisper Notes and transcribe offline. Perfect for extracting subtitles without uploading to cloud services. Is there a recording time limit? No limit. Record for hours if you want. Longer recordings just take more time to transcribe on your device. Does it support real-time transcription while recording? Not during recording, but yes during transcription—after you finish recording, you'll see the transcript appear in real-time as it's being generated. Do you support speaker labels (diarization)? Yes—fully offline. Tap the speaker icon on any transcript to see who said what, right on your device. We keep improving accuracy and speed. Where is my data stored? Only on your device. We have zero access. Note: If you delete the app, your recordings are deleted too (because we don't keep secret backups). Please export important files regularly. Can I summarize a transcript? Yes — copy it into whichever AI tool you prefer. Whisper Notes itself never uploads anything; your audio and text stay on your device. Why does transcription stop when I switch apps? iOS limits background GPU usage for third-party apps. Just return to the app and tap "Re-transcribe"—it will restart. Which devices are recommended? iPhone 12 and newer. Older devices (iPhone 11, iPhone SE 2nd gen) are not recommended—the app will not function properly on these devices. What languages are supported? English, Español, Français, Deutsch, Português, Italiano, Nederlands, 简体中文, 繁體中文, 日本語, 한국어, Hindi, Arabic, Русский, Türkçe, Polski, Українська, Tiếng Việt, Thai, Tagalog, Bahasa Indonesia, Svenska, Norsk, Dansk, Suomi, Čeština, Greek, Hebrew, Română, Magyar, Persian, Urdu, and 65+ more languages. ■ Contact Questions?

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.
