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.

Reminders & Calendar Widget brings your reminders, calendar events, and to-do lists together in one beautifully designed app with compact, information-dense widgets for your Home Screen. REMINDERS View all your Apple Reminders organized by status — overdue, upcoming, and anytime. Tap any reminder to edit its title, due date, priority, or list. Swipe to mark as done. Everything syncs with the built-in Reminders app. CALENDAR A full calendar view with a monthly date picker. Tap any date to see that day's events from all your calendars. Tap any event to open the native Apple event editor — edit title, time, recurrence, alerts, and more. Create new events directly from the app. TO-DO LIST A simple, focused to-do list stored locally on your device. Add items with optional due dates and priorities. Check them off from the app or directly from the widget. No account needed — your data stays on your device. SMART WIDGETS Three widget families — Reminders, Calendar, and To-Do — each available in Small, Medium, Large, and Extra Large sizes. Widgets adapt intelligently to your content: - Fewer items? Larger, more readable text with full sentences - More items? Compact layout that fits everything - Mark items as done directly from the widget - Customize background colors with 18+ theme presets - Configure how many items each widget size displays ADDITIONAL FEATURES - Live Activity support for reminders on Lock Screen and Dynamic Island - Dark, Light, and Automatic theme options - Guided onboarding to get started quickly - Full Spanish localization - Pull to refresh on all screens - Haptic feedback on actions Remi Calendar Widget nders & respects your privacy. Reminders and calendar data come from Apple's EventKit — we never collect or transmit your data. To-do items are stored locally on your device.

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.
