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

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

DayBlocks turns your upcoming calendar events and reminders into countdowns you can actually see. Time can feel slippery. "In three weeks" might as well mean "never" — until suddenly it's tomorrow and you're scrambling. DayBlocks changes that. Each upcoming event and due reminder becomes a row of colored blocks, with one block for every day remaining. Everything is sorted by what's coming next. As the date gets closer, the blocks shift from green to orange to red. It's a simple way to make time feel real. — FEATURES — - Reads events from calendars already connected to Apple Calendar, including iCloud, Google, and Outlook. There's no second calendar to maintain. - Works with Apple Reminders. Reminders with due dates appear alongside your calendar events as countdown blocks, so important deadlines don't slip past. - Shows glanceable countdowns for today and the next 30 days. Events further away appear automatically when they enter the 30-day window. - Uses color-coded urgency: red for today and tomorrow, orange for the next seven days, and green for later. The blocks tell you "soon" before you even read the event name. - Includes Home Screen widgets in small, medium, and large, plus Lock Screen widgets. See what's coming without opening the app. - Configure each widget individually. Long-press any widget to choose exactly which calendars and reminder lists it shows — keep a work widget on one page and a family widget on another. - Lets you choose which calendars and reminder lists appear. Toggle family, work, holidays, and other lists on or off so DayBlocks only shows what matters to you. - Designed for people who experience time blindness. No extra notifications, no clutter, and no productivity guilt. Just a clearer view of your time. — PRIVACY — DayBlocks accesses your calendars and reminders only to display your countdowns. Your calendar and reminder data is processed on your device. DayBlocks does not upload it to external servers, sell it, or use it for tracking. No account or login is required. — PERFECT FOR — - Anyone with ADHD or time blindness who needs to see time, not just count it - Parents keeping track of birthdays, appointments, and school events - Students whose deadlines often feel further away than they really are - Anyone who has ever forgotten a vehicle registration renewal or another important deadline

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.

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.
