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.
Point your camera at anything second-hand and see what it actually sells for.

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.

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.

Point your camera at anything second-hand and see what it actually sells for. Not an estimate. Not an AI's opinion. The number comes from real completed sales of the same item, and every one of those sales is listed underneath so you can check the work yourself. WHY THIS IS DIFFERENT Most valuation apps ask a language model what something is worth. We tested that approach against real market data: asked directly, the model was right about 3 items in 12. Priced from actual sold listings, the same photos got 5 in 12 — and the misses were far closer. When a model guesses a price it usually guesses low, which is how people end up selling a $3,000 watch for $50. Worthsy uses the model for one job only: working out what the object is. The price comes from sales that already happened. WHAT YOU GET • The median of what buyers actually paid, not what sellers are asking • Every comparable sale listed, each one opens the original listing • A chart showing where sales landed — the middle half, the outliers, the top end • Damaged and working items priced separately, so a broken one doesn't drag down your figure • Eight marketplaces, each in its own currency. We don't convert, because a converted price isn't what a local buyer pays WHEN WE CAN'T PRICE IT Sometimes the honest answer is "not enough data". If fewer than three real sales exist, we show no number at all — a price built on one sale isn't a price. And when your item looks like a genuine antique or a piece of fine art, we say so plainly: those sell at auction houses, not on the general resale market, and the listings we can find are usually reproductions. You'll see the number and exactly what it describes. BUILT FOR PEOPLE WHO SELL Every scan is saved, searchable, and works offline. Export the lot as CSV whenever you want. No account, no sign-up, nothing to remember. TRY IT FIRST Three free scans. No card, no trial that charges you later, no weekly plan hidden in small print. Worthsy Pro gives you 300 scans a month for $79.99/year or $19.99/month. Prices in your local currency are shown before you buy. The subscription renews automatically unless cancelled at least 24 hours before the period ends; manage or cancel it any time in your Apple ID settings, or from inside the app in one tap. Prices are estimated market data drawn from completed sales. They are not a formal valuation or appraisal. Terms: https://getworthsy.com/terms Privacy: https://getworthsy.com/privacy

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.

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.
