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

DFB is the award-winning app that lets you force any one of 100 items in a list. DFB X is the extreme version of DFB, bringing many more powerful features, settings and integrations, including: - Completely rewritten from ground up - Based on DFB, DFB X is a brand new app from the same developer, rewritten with modern features - New, more accurate Input Screen - Icons highlight on touch - Pull down for search - Fully customisable - Light and dark text colour - Set your own icon badges - Option to add background blur to imported wallpaper - Can toggle visibility to hide/show icons to match your setup - Prediction Notes - Use DFB for a brand new effect: Reveal multiple out predictions with DFB. - Instead of moving a list item to a location, swap out the entire note to just show the item at the input number. - Set prepended text that will appear before any reveal. - Comes with Mnemonica and other simple examples. For example: inputting “10” could reveal “I knew you would choose the two of spades” or “I knew I would meet someone born in October” - Brand new input methods - “Search Input” covert typing input using the familiar DFB 3x3 grid but on the keyboard - Customise to use any keys to suit your language - “Input flip” mode - auto swap digits entered for second input - “Web Control” input - share a URL to have an accomplice control your DFB X input number and text locally or remotely - “Voice input” - set the number in DFB X with your voice - Manual and gyro text inputs - dynamically update your force or any list item with input text - PeekSmith number recognition input - Clipboard input support - DFB X AI - In a pinch? Use DFB X AI to quickly generate lists for almost anything - DFB X AI can also generate dynamic list items for existing lists - For example, inputting “Oppenheimer” in performance with a list that has “Director of $$$” will cause that item to become “Christopher Nolan” - Uses AI credits - some free credits included, with more credits available for purchase - Badge Peek - Peek icon swipe inputs in a natural display. Perfect for filmed performances, or when mirroring your phone display to a large screen - Improved Classic Peek - Choose when it displays: either on every page or just to confirm on the last page - Peek numbers sent via input methods - Integrations - AWP Pro Mode integration - write any number or word to have DFB X auto update - WikiTest integration - automatically replace text in a note with what’s searched for on WikiTest - Earworm integration - use Earworm’s popular covert typing web search and notes input to automatically update specified text in any list - PeekSmith integration - number and text input through apps supported by PeekSmith - Third party app integration - works with any other app with API support - URL scheme to integrate with Shortcuts and more - Bluetooth remote input support - Supports the Atom remote, with more remote support planned - Number can be input whilst on any performance screen to instantly change the force location - Dummy notes enhancements - Dummy notes can now be placed anywhere for more realism - Can easily add/remove/hide dummy notes at will - More comprehensive settings - Hide list numbers - Lists can now appear more natural with no numbers displayed, ideal for shorter lists - Adjust reveal note font size settings to be more legible for parlour and stage performances - Option to show lists with the force item hidden - Quickly hide/show any note before performance - Swipe up from bottom to return to DFB X icon input home screen - no more tapping small buttons - Set language settings to match your region

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.
