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

"...a true notepad experience that may help you make a clean break from the pencil-and-paper era." -New York Times. Users describe Mental Note as "the only notepad app... that's actually better than, and as simple as, a pen and paper." It's "the future of note taking", and "a big sketchpad... [to] free associate and put stuff down in any format". Turn your iPhone into a digital notepad. Combine photographs, voice recordings, drawings and text - all on the same page, in any order you choose. An idea... a flash - a moment of genius. When a thought hits, and you have to remember it, why limit how you record it? The more context and sensory details you can capture, the clearer the idea can be put down. Use photographs, audio, sketching and text together on the same page... a digital page that can be shared with anyone. Mental Note allows you to capture ideas as they happen: use photographs, dictate, add text, sketch on anything. Ideas clarified. Creativity captured. FEATURES - Draw with your finger using multiple colours and widths on top of photographs, text, or anywhere else on the page. Zoom in to sketch fine details. - Take a photo or choose one from your album and add it to the page. - Add audio to the page by recording with your microphone. Continue to edit your note while recording. - Organize your notes using tags. - Password protect your private notes and flag your important ones. - Attach Calendar events to your notes. - Undo, redo anything in the note by shaking the device. - Delete note sections using the toolbar button or by swiping any note section. - Move a note section by swiping and then dragging it to its new location. - Length of a note is limited only by device memory. - Export in a variety of formats including PDF, text, Mental Note format, and more. Send using email, iCloud, Dropbox, and more. * Send a note in Mental Note format so the note may be imported into another person's Mental Note app. * Using email, export a complete note directly from Mental Note as either a PDF document or a picture (each audio recording is attached to the email as a separate file). You can also email just the text from your note. - Export your notes and backups to your iCloud and/or Dropbox account. - Share a note with your friends using most installed apps. - Map the location a note was created at (if location services are enabled). - Change the size and font of the text in your notes. - Change the color and background of your notes. - Numerous other configuration options. THIS VERSION IS OPTIMIZED FOR iPhone. FOR iPad, PLEASE SEE Mental Note for iPad. Read more: www.zymbiotic.com X @zymbiotic facebook.com/zymbiotic

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.
