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

Necrophonic is an ITC app used for spirit communication and EVP research. 8 Sounds Banks: The audio has been mastered in a way to bring out various sound properties . Using Pro Tools I was able to enhance high, mid, and low range frequencies. I also applied other filters to create unique sound characteristics to help layer the audio and create an environment suitable for spirit communication. The audio itself is made up of phonemes, partial words, reverse audio, foreign languages, and other parts of speech that can help spirits communicate. Besides some basic phonetic sounds such as na, no, da, do, di, ma, may, etc. there are no real words of phrases contained in the banks. These sounds banks play in a similar way to that of my other app "Spiritus Ghost Box" but instead of 4 sound banks Necrophonic has 8 active sound banks. White Noise Sound Bank: This app also has an optional 9th sound bank called "White noise". This bank can be used alone or with the other 8 giving you a total of 9 sound banks. This audio is taken for the internal sounds of the famous DR60 recorder that is known as the "Holy Grail" of EVP recorders. This is not a White Noise Generator, this is a normal sound bank like the others but this one contains white noise from the DR60. Audio Effects: This app does contain Echo and Reverb audio effects. These have been proven to be the best effects to apply to ITC sessions. The echo can create audio that can be manipulated within the echo itself. Echo can also help in live, real time communication by repeating the audio and allowing you to better hear whats coming through. Reverb can be applied to the audio to create a spacious sound environment that will enhance audio manipulation.

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.
