Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
Track the time you mean to spend. Most time trackers answer "where did my hours go?" OwnTime answers a better question: which of the things you care about are you neglecting right now? You define a small set of priorities — the parts of your life that actually matter — and give each one a daily budget. Then you start and stop sessions as the day unfolds. At a glance you see what still has time left and what you've been ignoring. IPHONE AND APPLE WATCH OwnTime works on its own on iPhone — start, stop, and log sessions, get budget alarms, and follow the live session on the Lock Screen and Home Screen. Add an Apple Watch and it becomes a first-class second surface, built for the next two seconds of intent: start, stop, glance. Your priorities and sessions sync directly between your own devices, and neither one needs the other nearby. BUDGETS, NOT TIMESHEETS Each priority has a daily budget, so neglect is visible at a glance — no spreadsheets, no billing, no projects. Optional alarms warn you before a budget runs out. YOUR DATA, IN A FILE YOU OWN One tap exports your complete history as a standard SQLite database — the same file the app itself uses. Open it with any tool you like, or keep it as a backup. No export format to decode, no account to request it from. PRIVATE BY DESIGN OwnTime has no server and no account. Your priorities and sessions live on your iPhone and Apple Watch and sync directly between your own paired devices over Apple's WatchConnectivity — never through us, never to the cloud. No analytics, ever. ALSO INCLUDED • Home Screen widgets (small and medium) with your remaining budget at a glance • Live Activity on the Lock Screen and Dynamic Island • Start, stop, and log past sessions with Siri and Shortcuts • Quick edits on iPhone or Apple Watch — name, daily budget, colour • Light and dark appearance OwnTime is for personal attention, not invoicing. If you want to see whether you're actually living by your priorities — not just logging hours — this is the tracker for you.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

Intermediate
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.
