A product spec, screen plans, and build steps for your coding agent.

Your first Build Kit is free with a verified email.
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.

When did you last change the sheets? Clean the coffee machine? Feed the houseplants? Little Duties gives recurring chores a home of their own, without cluttering your calendar or to-do list. See what needs doing at a glance, get an optional reminder when it’s due, and check it off when it’s done. SEE WHAT NEEDS DOING Get a clear view of what’s overdue, due today and coming up. From weekly laundry to those once-in-a-while jobs, know what needs your attention and what can wait. DO IT. TAP IT. DONE. The next reminder counts from the day you finish. Wash your towels every seven days? Whether you wash them early or a few days late, they’ll be due again seven days after you check them off. Tapped by mistake? Undo is right there. KEEP IT ON YOUR HOME SCREEN Small, medium and large interactive widgets give you a quick overview of due and overdue chores. Mark them done without opening the app. REMEMBER THE USEFUL DETAILS See when you last completed each chore and add notes to its history. Keep the details you’ll want next time, from which filter you used to where you put the spare descaling tablets. MAKE IT YOUR ROUTINE Choose how many days to leave between each chore and organise them with your own tags. Filter by room, garden, personal care or whatever makes sense to you. A NUDGE WHEN IT’S TIME Get an optional notification at 9 AM on the day a chore is due, with overdue follow-ups if you want them. Turn reminders on or off for each chore. YOUR CHORES, YOUR SPACE No separate account to create. Your data is saved on your device, with private iCloud sync when available. No ads or tracking. Export a readable backup to Files whenever you need one. Less to remember. More getting done. Requires iOS 26 or later. iCloud sync requires an Apple Account with iCloud enabled. This version supports backup export; backup import is not yet available.

Hypothesis 1
Assumption to check: No offline mode
Validate with people who use this workflow before building.
Hypothesis 2
Assumption to check: Sync issues
Validate with people who use this workflow before building.
Hypothesis 3
Assumption to check: Feature bloat
Validate with people who use this workflow before building.
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.
Not assessed in a Build Kit yet.
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.
