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.

24us is a quiet sanctuary for two. every hour of the day you both get one slot — share a photo, or share many, then the hour closes and the moment lives there forever. no feed, no followers, no likes. only the partner you paired with can see your album. there is no public profile. there is no algorithm. — how it works — · every hour, your moment. share as many photos as you like, hour by hour. when the hour closes, the slot is sealed. · just the two of you. a paired sanctuary — no third person can ever see what you share. the album lives between you and one other. · a year of small days. the shared calendar quietly glows brighter as the days pass. no leaderboards, just memory. · keep the streak alive. consecutive days where both partners shared build a streak. miss a day and it resets. quiet motivation, never pressure. · widgets on your home screen. your partner's most recent hour stays one tap away, even when the app is closed. — privacy first — we collect only what's needed to deliver the app. photos are stored behind short-lived signed URLs that only your pair can read. there is no analytics platform watching what you do. there are no third-party ads. we do not train any model on your photos. when a pairing ends, the entire shared album is permanently deleted within 30 days — for both of you. nothing about 24us survives the relationship if you don't want it to. — what 24us is not — it is not a feed. there is no scroll-forever timeline. it is not a social network. there is no friending, following, or DMs. it is not free. 24us is a one-time paid purchase — no subscriptions, no in-app purchases, no advertising. 24us is the place you put the small, real moments — the ones nobody else needs to see. requires ios 16 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.
