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

Not sure which knot you need? Knot IQ helps you choose the right one, then shows you how to tie it in true interactive 3D. Built by The Bear Essentials, Knot IQ is a practical knot-tying guide with 300+ knots for fishing, camping, climbing, boating, bushcraft, rescue, arborist work, scouting, and everyday rope work. Download the enhanced 3D knots you need and keep learning offline. CHOOSE WITH KNOTFINDER Start with the job, not the knot’s name. Answer a few quick questions about what you are doing. KnotFINDER narrows the choices, explains why each recommendation fits, and helps you compare your options. CONTROL EVERY STEP IN TRUE 3D Rotate the knot freely, zoom in, scrub through every step, reverse the sequence, pause, and change the playback speed. Adjust the rope colours for better visibility or switch to left-handed mode. LEARN WHERE AND WHY A KNOT WORKS Go beyond memorizing an animation. Review practical uses, strengths, trade-offs, and related knots. Interactive scenes show where knots belong in real situations: tap a task to see what to tie and where. 300+ KNOTS, ORGANIZED YOUR WAY Search by name, browse by activity or knot type, filter your library, save favourites, and build custom lists. Use the Downloaded filter to find the 3D knots you have saved for offline learning. Explore fishing and fly-fishing knots; camping and bushcraft knots; climbing, rescue, and firefighting knots; boating, sailing, and marine knots; arborist, hoisting, and rigging knots; scouting knots and lashings; plus necktie knots, shoelaces, household, utility, decorative, and specialty ropework. Learn essentials such as the Bowline, Clove Hitch, Figure Eight, Sheet Bend, Taut-Line Hitch, Trucker’s Hitch, Prusik, and Munter Hitch—plus hundreds of specialized bends, bindings, friction hitches, lashings, loops, splices, stopper knots, and quick-release knots. KEY FEATURES • 300+ knots and growing • True interactive 3D knot models • Rotate, zoom, scrub, reverse, pause, and change speed • Guided KnotFINDER recommendations with explanations • Offline access to downloaded 3D knot resources • Interactive scenes and practical use guidance • Rope-colour controls and left-handed mode • Favourites, custom lists, search, filters, and related knots • Expert guides and video tutorials from The Bear Essentials • One-time purchase with no ads or subscriptions • No data collected • Apple Family Sharing Made for beginners and experienced knot tyers alike.

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.
