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

Most yarn project trackers count one project at a time. Yarnify counts every piece - sleeves, body, hood - each with its own row count, pattern repeats, and starting offset, all tucked into one project. So when you come back to your work after a coffee break (or a three-week break), you pick up exactly where you left off. Yarnify is built for knitters and crocheters and syncs over iCloud across iPhone and Apple Watch, so your counts follow you wherever you craft. A PROJECT, BROKEN INTO PIECES A sweater isn't one count - it's a body, two sleeves, maybe a collar. In Yarnify, you create each piece inside the project with its own type (rows or rounds), pattern repeat, and starting row. The app shows your live count and how many pattern repeats you've completed, so you can stop doing arithmetic in your head. BIG COUNTERS THAT JUST WORK Every piece gets its own large, color-tinted counter, easy to tap one-handed while your other hand is busy. No squinting, no fiddling, no fear of losing your place. FINISH WITH A FLOURISH When you've woven in the last end, tap "Mark as Complete" to send your project off with a burst of confetti and a satisfying haptic high-five. Completed projects move to their own list, sorted by the day you finished them, with counters locked so you can't bump a row on finished work. AT A GLANCE, FROM ANYWHERE New widgets bring your works-in-progress to your Home Screen, Lock Screen, and Apple Watch: - Project Progress shows the most recently updated piece of any project, in the project's color. - Project Icon is a quick launcher tinted to match its project. - Yarnify Logo is a brand-colored shortcut into the app. Tap any widget to jump straight to the right project or piece. REMEMBER WHAT YOU USED Which needles did you reach for? What weight was that yarn? Save the details right alongside your counts - the needle or hook sizes you're using, the yarn weight, the size you're making, and free-form notes for everything else. Yarnify speaks both metric and US sizing and converts between them, so "4.0 mm" and "US 6" are just two names for the same needle. SEE EVERYTHING YOU'VE MADE Open Stats from Settings for a celebration of your craft: every project, piece, row, and round you've ever counted, your favorite needle and hook, and a breakdown by category. Your sheep sits in a ring that fills as you finish projects, carrying you up cozy milestones from First Stitch to Legendary Sheep. EVERYTHING IN ONE PLACE - Track every project piece by piece - sweaters, socks, blankets, amigurumi, and anything else on your needles or hook - 28 project categories, from sweaters and socks to baby booties, coasters, doilies, and pet sweaters - 13 project colors to match your stash, your yarn, or your mood - Pattern repeat tracking with automatic repeat counting - Custom starting row offsets, so you can pick up a project that's already underway - Save each project's needles or hooks, yarn weight, size, and notes - so you always know what you used and can pick the project up cold - Multiple needle or hook sizes per project, in metric and US, with automatic conversion - show your preferred system (or both) from Settings - Mark projects complete with confetti, haptic feedback, and a dedicated Completed Projects list - An Overall Stats screen with lifetime totals, your favorite needle and hook, and cozy milestones to reach - One-tap project duplication - perfect for second socks, matching mittens, and color variations - Home Screen, Lock Screen, and Apple Watch widgets that deep-link to your work - iPhone and Apple Watch app with iCloud sync - count from your wrist while you craft - Built-in unit converters for inches/centimeters and yards/meters - Reference tables for knitting needle and crochet hook sizes (US and metric) - Fully localized in English and German Yarnify is a small, thoughtful tool for people who'd rather spend their time making than keeping track. Get started - we'll keep your place.

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.
