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.

Calendar notifications are easy to miss. CalAlarms fixes that by turning your upcoming events into real device alarms that cut through silent mode and Do Not Disturb — just like your morning alarm. HOW IT WORKS CalAlarms reads your iPhone calendar and automatically schedules alarms before each event. No manual setup. No forgetting. Your phone wakes you up for what matters. 1. Pick which calendars to monitor 2. Set how far in advance you want to be alerted 3. CalAlarms handles the rest REAL ALARMS, NOT NOTIFICATIONS This is the key difference. CalAlarms uses Apple's AlarmKit to schedule actual device alarms — the same kind that wakes you up in the morning. They ring even when your phone is on silent. No more missed meetings because a notification got buried. BUILT FOR VIDEO CALLS Filter your alarms to only fire before events with video call links. CalAlarms detects Zoom, Google Meet, Microsoft Teams, and WebEx links in your events automatically. Get an alarm before every call, skip everything else. LIVE ON YOUR LOCK SCREEN When an alarm fires, a Live Activity appears right on your Lock Screen with event details. See what's coming up and dismiss when you're ready — no need to unlock your phone. STAYS IN SYNC CalAlarms syncs automatically in the background: - When you open the app - When your calendar changes - On a regular background schedule - When you move between locations Your alarms always match your latest calendar. FULL CONTROL - Choose alarm offset: 1 to 60 minutes before each event - Schedule alarms up to 30 days in advance - Toggle individual alarms on or off - Include or exclude all-day events - Filter by specific calendars - iCloud sync across your devices PRIVACY FIRST CalAlarms reads your calendar data on-device. Nothing leaves your phone. No accounts to create, no data collected.

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.
