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.

Cine Meter II measures light and color, so you can light and shoot and know what you'll get. “Cine Meter II is an essential app for every cinematographer.” — Jon Fauer, ASC “[T]he perfect app to have with you at all times.” — Roberto “Ganzo” Schaefer, ASC, AIC It's a zoomable spotmeter with an RGB waveform monitor and a false-color picture. It's an incident meter using a Lenny Hat or other diffusion, or Lumu™ Lite attachment, with lux and foot-candle readouts. (Lumu Power is NOT supported, and flash metering is NOT possible.) It's a color meter, showing color temperature and green/magenta tint, and giving you corrections to or from your target color. Measure more than just shutter-priority or aperture-priority: calculate shutter speed, shutter angle, aperture, ND, or ISO directly. • The exposure meter shows your stop as a decimal value (for cameras with EVF iris readouts) or as a full stop and fraction (for cine lenses with marked iris rings). Cine Meter II lets you use shutter angles – ideal for Digital Bolex and Blackmagic cameras – as well as speeds, and you can dial in ND filters and arbitrary exposure compensations. The spotmeter is zoomable up to 15x magnification (on devices that support camera zooming), using either the front or back camera. • The waveform monitor shows you how light levels vary across a scene. You'll see how smooth and even the lighting is on a greenscreen or background, and find subtle hotspots and shadows at a glance. The waveform’s RGB mode shows you color imbalances in the image and gives you a handy way to check color purity and separation for chroma-keying. • False-color mode lets you define allowable contrast ranges, and see instantly which shadows are underexposed and what highlights risk clipping. _______________________ READ BEFORE YOU BUY: Cine Meter II is NOT a flash meter; it can't measure strobes. Cine Meter II does NOT work with Lumu Power (the Lightning port Lumu), only Lumu Lite (the headphone jack Lumu). Cine Meter II gives you *absolute* light meter readings, but *relative* picture and waveform monitor levels: Cine Meter II’s picture and waveform monitor do not use the *exact* exposure shown by the light meter (they are close to the meter reading, but can differ from it slightly). The picture and waveform monitor show you *relative* levels within a scene, not *absolute* levels based on the meter reading. Shutter speeds, apertures, and ISOs shown in Cine Meter II are for metering purposes only and do not control the shutter speed, aperture, and ISO of the iPhone camera. The iPhone camera uses whatever exposure settings it needs to capture a reading. Cine Meter II is a light and color meter only; it is *not* a camera simulator.

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.
