Generating… usually about a minute.
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.

Stop overpaying for shipping. PackShip finds the perfect box, compares UPS, USPS, and FedEx rates instantly, and shows you exactly how to pack it in 3D, so every shipment goes out at the lowest price possible. Built for eBay flippers, Mercari sellers, Etsy shop owners, Poshmark resellers, and anyone who ships from home. Stop guessing box sizes. Stop overpaying for dimensional weight fees. Ship smarter in seconds. WHY PACKSHIP • The average reseller overpays 2 to 7 dollars per package because they use the wrong box. Multiply that by 50 shipments a month and you are leaving 100 to 350 dollars on the table every single month. PackShip closes that gap. • Most shipping apps just show you prices. PackShip optimizes the entire shipment, from the item you are sending all the way to the carrier you ship it with. SMART BOX FINDER • Tell PackShip what you are shipping. The app picks the smallest box that fits, so you avoid dimensional weight charges that quietly eat into your margin on every order. No more grabbing whatever box is in the corner of the room and hoping for the best. AI ITEM SCAN • Just type the item name. PackShip pulls accurate dimensions and weight in seconds. No measuring tape, no calipers, no guessing. If you are listing fast and shipping faster, this is the feature that gives you your time back. AR MEASURE • Shipping something obscure with no standard size? Point your camera at it. PackShip measures length, width, and height in real time, right in the app. Works on anything from a vintage lamp to a stack of trading cards. 3D PACKING PREVIEW • See exactly how every item fits inside the box before you tape it shut. No more wondering if it will fit, repacking three times, or upgrading to a larger box at the last minute. The 3D preview shows you the optimal arrangement up front. LIVE RATE COMPARISON • Real-time UPS, USPS, and FedEx prices, side by side. Ship with whoever is cheapest for that exact box size and destination, every single time. Carriers do not always win on the same routes, and PackShip catches the difference automatically. SHIPPING LIBRARY • Save every package you have shipped. Sold the same item again? PackShip remembers the box, the dimensions, and the cheapest carrier. One tap to reship. Perfect for resellers who move the same inventory categories week after week. BUILT FOR RESELLERS • If you sell on eBay, Mercari, Poshmark, Depop, Etsy, Whatnot, or Facebook Marketplace, PackShip pays for itself in one shipment. The app is designed around the specific shipping patterns of resellers, not enterprise logistics teams or warehouse operations. PERFECT FOR • eBay sellers and flippers • Mercari, Poshmark, and Depop resellers • Etsy shop owners • Whatnot live sellers • Small e-commerce stores • Home-based shipping operations • Gift senders and occasional shippers • Anyone tired of overpaying for shipping SAVE ON EVERY SHIPMENT • Avoid oversized package fees. Skip the wrong-box markup. Stop accepting whatever rate the first carrier shows you. PackShip puts the best decision for every single shipment in your pocket, in seconds. Pack smarter. Ship cheaper.

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.
