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.

Most task apps wait to be asked. This one speaks first. It holds your commitments and your todos, works out what deserves your attention right now, and follows up afterwards to find out what actually happened. THE DAY, NOT THE LIST The home screen is what's left of today, drawn to scale: the time you still have, set against everything you still owe. When a meeting runs long, it recomputes. When you say you're spent, it surfaces the work that doesn't ask much of you. COMMITMENTS AND TODOS ARE DIFFERENT THINGS A commitment occupies a block of wall-clock time. You can be in only one at once, and two of them can conflict. A todo comes due at a moment but reserves no time, so todos never conflict and can pile up. Calling someone at 8pm is a todo. Dinner is a commitment. Collapse the two into "tasks" and you lose the ability to say when a day simply will not fit. When something has been carried for weeks without moving, promote it — give it real time on the calendar, with a find-a-time flow that works around what is already there. CHECK-INS: WHAT ACTUALLY HAPPENED At the end of a commitment or a todo, you get one question. Did this happen? Done, partly, didn't happen, still going. One tap, answerable from the Lock Screen. Your answers are the only thing the app treats as fact. Nothing is inferred from your location, your motion or your Focus mode. And when check-ins go unanswered, it says so — that today's plan is built from intentions rather than facts — instead of showing you a stale day and calling it accurate. IMPORTANCE AND URGENCY ARE NOT ONE AXIS Importance is how much follows from something not happening. You declare it, and it holds. Urgency is how close something is to being too late — read from the clock, never declared, always current. Kept apart, so "quiet but consequential" and "loud but trivial" never look alike. Add energy level, place and category, and you can ask the question that actually comes up: what can I do at my computer, in twenty minutes, while I'm tired? TWO KINDS OF REPEATING Fixed recurrence comes from the calendar alone — the last Friday of every month, whether or not you did the last one. Completion recurrence measures from when you actually finished: two weeks after the grass was last cut. Finish late and the next one moves late. They are different machines, and they behave differently. CAPTURE THAT DOESN'T INTERROGATE YOU Speak or type. It never stops mid-sentence to ask a clarifying question. It makes a guess, then shows you the guess, labelled, so you can correct it later at no cost. "I guessed the time." Nothing reaches your calendar without your confirmation first. IT INTERRUPTS ON A BUDGET There is a limit to how much of your attention it will spend on its own initiative each day. That budget contracts when you stop responding and expands when you engage. Nothing it declines to interrupt with is discarded — it waits somewhere that costs you nothing, and you can always ask why a given thing didn't fire. When one prompt goes unanswered, it grows more persistent rather than louder: a notification, then time-sensitive, then a Live Activity pinned to your Lock Screen until you answer it. PRIVATE BY CONSTRUCTION No account. No login. No server. Your data lives on your device and syncs only across your own devices. There is no team, no sharing, no collaborators and nothing to sign up for. Your history is yours to delete at any time, and deleting it won't break your recurring items. Commitments are written into your system calendar, so they appear on your Watch, in CarPlay and anywhere else you already look — always after you've confirmed it, and always saying why. Requires iOS 26 or later. iPhone only.

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.
