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.

Welding Symbols Pro is the only dedicated welding symbols app on the App Store. A complete chart of the basic weld symbols, a live symbol builder that reads any symbol back in plain English, and a quiz that drills you for the print and for the test. Pay once. Works offline forever. THE BUILDER IS THE DECODER Set what you see on the print: system, weld type, side, size, depth and throat, groove angle, root opening, length and pitch, contour and finish, weld all around, field weld, melt through, tail reference. The symbol draws itself live, and below it the app speaks the exact sentence a welder would say. No camera, no AI, no guessing. Illegal combinations are blocked with a one-line reason, so you also learn what a symbol can never say. THE FULL CHART, ONE TAP DEEP All 16 basic weld symbols: fillet, square, V, bevel, U, J, flare V, flare bevel, scarf, plug and slot, spot and projection, seam, stud, back and backing, surfacing, and the A2.4:2020 edge symbol. Plus every supplementary symbol, the finish letters C, G, H, M, P, R and U, and a map of where each dimension goes. Every symbol opens a detail view with a plain-English meaning and a cross-section of the finished joint. Search for "bevel", "flag", "G" or "pitch" and go. AWS AND ISO, BOTH Symbols in AWS A2.4 style and in ISO 2553 System A and System B: the dashed identification line, a and z fillet sizes, inches and millimeters. Built for prints that cross the ocean. QUIZ FOR THE TEST Read mode shows a symbol and four sentences. Build mode shows a sentence and four symbols. Ten-question rounds, a streak counter, and a timed 90-second warmup for CWI Part A. Every question is generated from the same engine that draws the chart, so all 16 basic symbols come up. BUILT FOR THE TRADE · 100 percent offline. Nothing to sign in to, nothing to sync. · One price. No subscription, no ads, no account. Anonymous usage statistics only, never what you build. · Fractions first: 1/4 in reads as 1/4 in, not 0.25. · Share any symbol as a clean image card for an apprentice or a group chat. · iPhone and iPad. WHO IT IS FOR Welders and fitters reading shop drawings. Fabricators, ironworkers and boilermakers. Welding students in every blueprint reading class. CWI candidates warming up for Part A. THE FINE PRINT Educational reference. The drawing and its notes govern; when in doubt, ask the engineer of record. This app never gives welding procedure, machine settings, or strength advice. Notation semantics follow AWS A2.4:2020 and ISO 2553:2019, explained in the app's own words and drawings. Not affiliated with AWS or ISO.

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.
