A product spec, screen plans, and build steps for your coding agent.

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.

``` Face Scanner turns the TrueDepth camera on your iPhone into a facial measurement tool. Capture a 3D scan of your face in seconds, then explore every reference measurement used by plastic surgeons, oculoplastic clinicians, and facial aesthetics researchers. WHAT YOU CAN MEASURE • Interpupillary distance (IPD) • Intercanthal and outer canthal distance • Palpebral fissure length and height (per eye) • Canthal tilt (per eye and average) • Alar base width • Nasal length and Goode tip-projection ratio • Nasolabial and nasofrontal angles • Philtrum length, lower-face height, thirds ratio • Ricketts E-line upper- and lower-lip offsets • Bizygomatic width, bigonial width, FWHR • Orbital vector (cornea vs infraorbital rim) • Secondary ratios used in modern aesthetic analysis (IPD : bizygomatic, alar : IPD, philtrum : lower face, and more) 3D OVERLAY SYSTEM Every measurement can be toggled as a graphic overlay on your 3D scan. Angles show clear reference lines, arcs, and vertex anchors. Distances show landmark dots and a connecting line. Ratios show two distinct segments side-by-side. Tap multiple measurements to compare them on the same model, each in its own color. HISTORY AND TRENDS Every scan is saved locally on your device with its measurements. The history view lets you pick which measurements to track and see them across scans in a table or a line chart over time. Watch real progress without any guesswork. AESTHETIC-TARGET RATINGS Section-level ratings compare your measurements to documented aesthetic targets from Farkas's anthropometric norms, neoclassical canons, Ricketts' E-line, Peck & Peck's lower-third analysis, Goode's tip-projection ratio, and Powell & Humphreys' aesthetic face angles. Sources are cited in the Instructions screen so you always know which reference a number is compared against. PRIVACY FIRST Every scan stays on your device. Nothing is uploaded. Nothing is shared. No account required. WHAT'S FREE • Unlimited 3D face scans • Every visual measurement overlay • In-app instructions with references WHAT UNLOCKS WITH PREMIUM ($4.99, one-time) • Numeric values for every measurement • Aesthetic-target rating per section • Saved-scan browser • Multi-scan history and trend charting • One-time purchase — no subscription IMPORTANT Face Scanner is a measurement and tracking tool for personal reference and education. It is not a medical diagnostic device. Aesthetic target ranges are references, not goals. The app does not generate an "attractiveness score" and the developers intentionally avoid that framing. Requires an iPhone or iPad with a TrueDepth camera (Face ID capable).

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.
