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

For summer 2026, we have added NFC functionality. You can write an NFC tag with your guest feeding URL. Anyone with a smart phone can then scan the tag and run your guest feeding site. The Bluetooth BLE discovery has been cleaned up to you won't see 2 names for the same device - after you have renamed one of your feeders or clickers. This is a limitation of iPhone where the bluetooth remembers a device the first time you "discover" it. So if you change its name (through our messages or BLE) the iPhone still thinks it's the old name. But the advertisement has the new name. So I figured out how to cache the new name and use it instead of the old (remembered) name. Hopefully this cleans up things. Support for 26.3. 2026 is the year of IoT control for my #Abilities users. Kona Currents, LLC offers a unique Remote Education and IoT processing app for creation, collection, processing, search, and messaging of optical visual markers we call Semantic Marker (R). An innovative text and optical search engine is included, along with an API for processing optical labels, barcodes and two-dimensional codes. These optical image and data files are downloadable for internal and external use. This app interacts through published API's with Cloud Computing services. The app will communicate via MQTT messaging among a suite of IoT devices, as well as using Bluetooth Low Energy (BLE) directly to devices, which is especially useful to set credentials such as WIFI passwords for the IoT devices (ie. ESP 32 devices). See SemanticMarker.org for more on the abilities use. - We have one user using Eye Tracking to send messages to reward his service dog over our IoT framework! #Ability Now for Summer 2025, is the support for Space and Time of your Semantic Marker(R). This includes GPS and Time that is extracted from the meta-data of your markers. The Map will now show the markers in their geospatial location. See the map above where the optical visual markers, which represent music artifacts, are placed at where the concert was recorded. The date of the events are also tagged - and stored in the photo for sharing outside the Semantic Marker(R) framework. Now think of real-estate or other location based artifacts: tag with a Semantic Marker(R) and the marker is much more valuable. https://semanticmarker.org/users/common/MusicMatrixSM.png

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.
