What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

MacroDuo is macro tracking built for two. Log your meals, hit your protein, carb, and fat goals, and stay motivated with the person you care about most. Most diet apps make you go it alone. MacroDuo links you with your partner so you can see each other's progress, keep your streaks alive, and send a cheer when one of you crushes the day. WHY MACRODUO • Built for couples — link with your partner using a simple code and tackle your goals together. • Fast meal logging — search foods, scan barcodes with your camera, and save your go-to "quick adds." • Macros that make sense — set calorie and macro targets and watch your daily rings fill up. • Streaks that stick — build your own logging streak and a shared "together" streak you keep alive as a team. • Cheers — send your partner a little encouragement when they're on track. • Apple Health sync — bring in your weight, body fat, steps, and active calories, and send your logged nutrition back out. GOALS THAT FIT YOU Onboarding builds your daily calorie and macro targets from your age, sex, height, weight, and activity level. Pick Weight Loss, Maintenance, or Muscle Gain — or set fully custom macros. Make the app yours with light and dark themes and custom accent colors. LOG IN SECONDS Search a food, scan a barcode, or tap a quick add. Adjust servings and the macros scale automatically. MacroDuo keeps the foods you eat most right at your fingertips, so logging takes seconds — not minutes. REACH YOUR GOALS, TOGETHER Once you're linked, you'll see your partner's daily progress, recent meals, streaks, and an overall progress total. Send cheers, chase a shared streak, and take on the daily challenge to both hit your goals. PRIVACY YOU CAN TRUST Your partner sees a shared progress view — daily macros, streaks, and an overall progress total — never your raw weight history or body-fat readings. Your health data is only ever used to power features inside the app. It is never sold and never used for advertising. SUBSCRIPTION MacroDuo offers a 7-day free trial, then a subscription to unlock the full experience: • Single (monthly) — full access for you. • Partner (monthly) — covers you and your linked partner on one subscription. • Couple (annual) — the same partner coverage, billed yearly at a discount. Payment is charged to your Apple ID at confirmation of purchase. Your subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your App Store account settings. Any unused portion of a free trial is forfeited when you buy a subscription. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://macroduo.replit.app/privacy Whether you're cutting, bulking, or just trying to eat better as a team, MacroDuo turns tracking into something you do with someone — not something you do alone. Download MacroDuo and start your streak today.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
