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

SpellRBoard is a simple, effective, and accessible digital letterboard app designed to help individuals who are unable to communicate reliably using their voice. Whether due to speech impairments, neurological conditions, or other challenges, SpellRBoard allows users to spell out words and phrases using an alphanumeric letterboard. Paired with text-to-speech technology SpellRBoard offers an easy-to-use platform for those in need of an AAC (Augmentative and Alternative Communication) solution. SpellRBoard removes the clutter of ads, pop-ups, and ongoing payments so that users can focus solely on what matters most: communication. Key Features: • Ad-Free, No Additional Costs: SpellRboard is a one-time purchase with no hidden fees, no ads, and no in-app purchases. All features are included at the time of purchase, offering a hassle-free experience. No registration is required. • Alphanumeric Letterboard: SpellRboard uses a digital alphanumeric letterboard that includes all the letters of the alphabet, numbers, and commonly used symbols. The letterboard is easy to navigate and designed for fast and reliable spelling, allowing users to create complete thoughts by selecting individual letters. • Text-to-Speech (TTS) Output: Using Apple’s proprietary Text To Speech synthesizer. • Save/Copy Options: Easily save your spelling sessions to other apps like the Notes app. • Customizable Speech Settings: Choose from a variety of voices and adjust speech speed, pitch, and volume to ensure the voice output meets individual preferences and needs. • Offline Functionality: SpellRboard works without requiring an internet connection, ensuring that users have reliable access to the app at all times, whether at home, on the go, or in settings where internet access is unavailable. Currently we support the following languages: • English TTS Voices with English Alphabet. • French TTS Voices with English Alphabet • Spanish TTS Voices with Spanish Alphabet • Dutch TTS Voices with English Alphabet • Greek TTS Voices with Greek Alphabet Note From Developer: I designed this app originally for my younger brother, who has autism and is non speaking. My family has been helping him learn to communicate using a letteboard, where he points to each letter, spelling out whatever he wants to say. I realized that I could create a digital version of a letterboard so he could spell independently. I was encouraged to publish the app and refine it, so that it could be accessible to all. SpellRBoard- because everyone has a voice and deserves to be heard.

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.
