Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
Trackalot helps you log repeatable events the moment they happen. Create folders for areas of life like Health, Pets, Work, or Routines. Add trackers inside each folder, then tap any tracker to save a timestamped entry immediately. Long-press when you want to add a note or value, and swipe into a tracker report when you want to understand the pattern. Trackalot is built for quick everyday logging: - One-tap trackers for fast timestamped entries - Optional notes and numeric values for extra context - Folders to keep related trackers organized - Per-tracker charts for 7 days, 30 days, 90 days, or 1 year - Stats for total count, today, this week, and current streak - Entry history with edit and delete controls - Home Screen widgets for frequent one-tap logging - CSV and JSON export for analysis, backup, or archiving - Manual backup and restore support - Light, dark, and system appearance options - Optional haptics and sound effects Use Trackalot for habits, routines, symptoms, medication, pet care, focus blocks, meals, hydration, chores, workouts, mood checks, or anything else you want to count without friction.

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.
