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.

Some pilots, at the critical moment, switch off their targeting computer and go with their gut. Yours now tells the time — so maybe leave it on. A wireframe tunnel. Red range lines closing in. A crosshair that locks on and holds. Stay On Target turns your Apple Watch into a 1970s vector targeting display, with the time underneath in a big angular red readout. It is, technically, a clock. Spin the crown and the radio crackles — short pilot callouts, recorded for this app. Tap the date and your week scrolls away into the distance as a text crawl: today, tomorrow, and every day after that with something on it. Drag it with a finger or spin the crown to move through at your own pace. Nothing booked? It says so, and it sounds pleased for you. FOUR UNITS - ANq 3.6 — the tunnel: receding frames and rays, a twelve-second loop of range sweep, lock-on and chevrons. Amber or phosphor green. - T-s7b — the range grid: two gridded gates swinging through space, gold on crimson, a ship marker between them, contacts curving past. The gates fill with your rings. - DS-1 — the orbital approach: a red planet edge to edge, a green moon coming out from behind it as your Move ring fills, stars lighting with Exercise, a reticle filling with Stand. Close everything and it locks on. - YV-4 — the base tracker: the war room's plotting table. A planet dead centre, a tracker coming round it with a flashing red cone of sight that eats into the green as your Move ring fills, until it lands on your moon. Stand lights the rim scale, Exercise grows the moon. Long-press for SYSTEMS to switch units. KEY shows what each readout means. ON IPHONE TOO The iPhone app is the console the display is mounted in: each unit on its own screen shape, with the date, clock, ring bars and your next appointment around it. Turn it sideways for the full console, or press FULL and keep only the display. The Mission Briefing crawl plays across the whole screen. One purchase covers both. TWO GAMES Tap GAMES on the iPhone console. Both are included. Dust Runners: haul relief cargo across a desert world on a hover speeder. Twenty runs over a day shift and a night shift. Keep right, dodge the haulers, hop the rocks, blind raiders with dust and deliver on time. Three speeders, a garage of upgrades, three stars on every run. Pilot training simulator: take the controls. Twenty short missions: dogfights, convoy escorts, carrier strikes and low runs down a narrow channel, each with its own sky and its own twist. Earn up to three stars on every mission, replay for the ones you missed, and open the next. The cockpit's targeting computer is the ANq 3.6 from this app. WHAT IT DOES - Always-on display: the clock keeps time while the animation rests - Amber or phosphor green on the tunnel — tap to switch cockpits - Radio callouts on the crown — every unit has its own, and two of them read the dial to you — silenced with one tap when you're in a meeting and your wrist starts talking - Mission Briefing: your week's appointments as a receding crawl — drag or spin to scrub through it - Rings, steps, resting heart rate and last night's sleep, read straight off the watch - Countdown timers on the watch: turn the crown to set, tap the clock to start - 12 or 24 hour, whichever way you were trained - The watch app runs on its own; the iPhone app is optional. No account, no setup - Collects nothing. We genuinely have no idea who you are Tip: Settings → General → Return to Clock → 1 hour. Now it stays up like a real watch face every time you raise your wrist. Don't get cocky. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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.
