Evidence scope: No current overall US chart position is available. Category-chart positions shown in discovery are a separate scope. Revenue is a directional model estimate, not verified earnings.
A product spec, screen plans, and build steps for your coding agent.
First kit free with a verified email
Combine features and design from your favorite apps.
Your first Build Kit is free with a verified email.
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.

Ever held something and wondered, what is it worth? Primo Worth turns your camera into a pocket appraiser. Snap a photo and get a real-world estimate in seconds. WHAT YOU CAN VALUE - Antiques, art, furniture, ceramics, silver and clocks - Jewelry and watches, with metal, karat and hallmark details - Coins, banknotes, bullion and tokens - Collectibles and vintage finds - Everyday items you are ready to sell FOUR SCAN MODES - Item: value almost anything you own - Jewelry: jewelry and watches, plus metal, karat, hallmark and era clues - Antique: antiques, art and furniture, plus era, origin, material and maker marks - Coin: coins and banknotes, plus denomination, date, mint mark and composition HOW IT WORKS 1. Pick a mode and take a photo 2. AI identifies the item, brand, category and condition 3. We compare it against real eBay sold listings from the last 90 days 4. You get an estimated value, a price range and the actual comparable sales behind it When there are no recent sold listings, Primo Worth falls back to a careful web-based estimate, so you are never left guessing. WHY PRIMO WORTH - Real sold prices, not hopeful asking prices - See the comparable sales, so you can trust the number - Private by design: no account needed, and your photos are sent for analysis but never stored on our servers - Choose your currency: USD, EUR or GBP - Your scan history stays on your device Whether you are clearing an estate, sorting an inheritance, hunting at a flea market or just curious about a drawer full of odds and ends, Primo Worth gives you a fast, honest starting point. Estimates are for guidance only and are not a certified appraisal. Point, shoot and find out what it is really worth.

Hypothesis 1
Assumption to check: Limited item identification accuracy
Validate with people who use this workflow before building.
Hypothesis 2
Assumption to check: Slow loading times for image processing
Validate with people who use this workflow before building.
Hypothesis 3
Assumption to check: Lack of detailed item information

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.
Not assessed in a Build Kit yet.
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.
